Abstract
We present a new sample of northern isolated galaxies, which are defined by the physical criterion that they were not affected by other galaxies in their evolution during the last few Gyr. To find them we used the logarithmic ratio, f, between inner and tidal forces acting upon the candidate galaxy by a possible perturber. The analysis of the distribution of the f-values for the galaxies in the Coma cluster lead us to adopt the criterion
for isolated galaxies. The candidates were chosen from the CfA catalog of galaxies within the volume defined by
km s-1, galactic latitude higher than
and declination
.
The selection of the sample, based on redshift values (when available), magnitudes and sizes of the candidate galaxies and possible
perturbers present in the same field is discussed. The final list of selected
isolated galaxies includes 203 objects from the initial 1706. The list contains
only truly isolated galaxies in the sense defined, but it is by no means complete,
since all the galaxies with possible companions under the f-criterion but with
unknown redshift were discarded. We also selected a sample of perturbed galaxies
comprised of all the disk galaxies from the initial list with companions (with
known redshift) satisfying
and
km s-1; a total of
130 objects. The statistical comparison of both samples shows significant differences
in morphology, sizes, masses, luminosities and color indices. Confirming previous
results, we found that late spiral, Sc-type galaxies are, in particular, more
frequent among isolated galaxies, whereas Lenticular galaxies are more abundant
among perturbed galaxies. Isolated systems appear to be smaller, less luminous and
bluer than interacting objects. We also found that bars are twice as frequent among
perturbed galaxies compared to isolated galaxies, in particular for early Spirals
and Lenticulars. The perturbed galaxies have higher
/
and
/
ratios, but the atomic gas content is similar for the two samples.
The analysis of the luminosity-size and mass-luminosity relations shows similar trends
for both families, the main difference being the almost total absence of big, bright
and massive galaxies among the family of isolated systems, together with the almost
total absence of small, faint and low mass galaxies among the perturbed systems. All
these aspects indicate that the evolution induced by interactions with neighbors
would proceed from late, small, faint and low mass Spirals to earlier, bigger, more
luminous and more massive spiral and lenticular galaxies, producing at the same time
a larger fraction of barred galaxies but preserving the same relations between global
parameters. The properties we found for our sample of isolated galaxies appear similar to those of high redshift galaxies, suggesting that the present-day isolated
galaxies could be quietly evolved, unused building blocks surviving in low
density environments.
Key words: galaxies: interactions - galaxies: evolution - galaxies: spiral
Galaxies are most commonly found in aggregates of different densities. Inside these aggregates, the observed morphology and the segregation of types (Fasano et al. 2000; Dressler et al. 1997) may have been determined by the local density of matter and by the subsequent interactions between galaxies. Exchanges and interaction with its neighbors can affect the galaxies global properties and their star formation rates, as shown by the members of dense groups or pairs (Moles et al. 1994a), even if the effects, in general, are not as dramatic as they are in the strongest cases (Moles et al. 1994b; Márquez & Moles 1999).
Another way to look into the effects of interaction on the overall equilibrium of a galaxy is through the analysis of the relations found between the structural parameters for different families of galaxies. The E/S0 cluster (Faber et al. 1987; Davis & Djorgovski 1987; Jørgensen et al. 1996), and field galaxies (Treu et al. 2001) satisfy the Fundamental Plane (FP) relation, even if its form is not the same for both families. The Spiral (S) galaxies satisfy the Tully-Fisher (TF) relation. It has been indicated that the TF relation defined by isolated spiral galaxies presents a smaller scatter than non-isolated galaxies (Márquez & Moles 1996; Márquez et al. 2002; van Kannappan et al. 2002).
To find isolated galaxies, a physically grounded and operational definition of isolation has to be given. Often the term field galaxies refers to systems that are not in dense aggregates, but frequently they are still under the influence of neighboring galaxies and cannot be considered as genuinely isolated objects (see for example Márquez et al. 2002). The first systematic compilation of isolated galaxies was made by Karachentseva (1973), who used as the main criterion that they do not show companions within 20 diameters in the PSS plates. Later, Turner & Gott (1976), while searching for groups of galaxies, found that some of the galaxies could not be assigned to any of the identified groups. It was argued that they would trace a cosmological homogeneously distributed population of galaxies. This conclusion was however challenged by Huchra & Thuan (1977) who used a deeper sample (
instead of
). Vettolani et al. (1986) adopted stricter criteria to find isolated galaxies. Their conclusion was that it was very unlikely that there was a cosmological component of galaxies without any kind of clustering (at least at small redshift). But an important observation was the detection of galaxies in such poor environments that they had very probably evolved without any external perturbation, as if they were isolated. In that perspective what is needed is an operational definition of isolation that could lead to identifying galaxies that have evolved free from external influences for most of their lives, a point of view adopted by Márquez & Moles (1996) and Márquez et al. (1999). In this context, it was noticed that non-axisymmetric structures like bars, tails or plumes, which are usually explained invoking gravitational interaction with companions or satellites, can also be present in isolated galaxies, posing the problem of their origin in the absence of sizable interactions (Moles et al. 1994, 1995).
In the present work we discuss the criteria used to find isolated galaxies and build a statistically well-defined sample to analyze their properties. Due to the lack of redshift information for most of the faint, possible perturbers, the final sample is by no means complete, our main goal being to keep only truly isolated galaxies, discarding all the suspect systems. In the last section we compare the properties of the family of the isolated galaxies with those of confirmed perturbed galaxies.
We also consider the similarity of some of the properties of present-day isolated systems with those reported for the presumed building blocks in the distant Universe (Trujillo et al. 2003; Ferguson et al. 2003). Stellar systems situated in regions of very low density would have evolved differently from galaxies in aggregates without a significant contribution from the surroundings and, therefore, they might be similar to those original building blocks.
From an operational point of view, we will consider a galaxy to be isolated when its evolution in terms of structure and stellar content has been dominated by internal forces for most of its life. Or, in other terms, when the external forces are judged to be unable to have produced noticeable changes in at least the last
years. As found by Athanassoula (1984) and Byrd & Howard (1992), an external interaction can only have influence on the structure of a given system when the corresponding tidal force amounts to
1% of the internal force.
The results of numerical simulations of encounters between
galaxies can be described in terms of a tidal
perturbation parameter (see Byrd & Howard 1992).
This gives the ratio between the tidal force exerted by the
perturber, P, on the primary galaxy, G, and the internal
force per unit mass in the outer parts of the primary. Given
a galaxy of mass
and size R, and a perturber
of mass
with a closest approach pericenter distance given by b, that ratio is
Regarding the pericenter parameter, b, Icke (1985), when studying the influence on the gas in the disk of a galaxy of the flyby of another galaxy, found that the maximum pericenter distance still able to trigger star formation in the gas disk is given by
Since the pericenter parameter b cannot be directly estimated, we adopted instead
the projected distance
between the galaxy and the perturber on the plane of
the sky at the primary's distance. Thus, the final expression for the perturbation
parameter is
In fact
can be greater than the impact parameter, b, depending on the orbit type, the orientation of the line of nodes with respect to the observer and the position of the perturber on its orbit around the primary, all quantities totally unknown. In those cases a galaxy would be judged more isolated (i.e., smaller f-values) than it really is, which would compromise our selection criterion. The error in f assuming
instead of b is
.
As we will see, given that we are going to make a statistical use of f, and the restrictive limits we impose in order to consider a galaxy as isolated, the adopted criterion is robust enough and only in very extreme (i.e. very improbable) cases, a perturbed system might be considered as isolated.
The theoretical results by Athanassoula (1984), Byrd & Howard (1992) and Icke (1985) consistently show that values of
are required to produce sizable effects on a given disk galaxy. However, before fixing the limit f-value to consider a galaxy isolated, we must consider the fact that we are using rather rough estimates for the masses of the galaxies and for the pericenter distance. Thus, systems with f-values now observed to be smaller than -2 could had have presented larger values in the past, depending on the details of the orbit and of the reaction to the interaction.
To evaluate the typical f values existing in well defined galaxy aggregates, we studied their distribution for the galaxies of the Coma Cluster. As far as it can be considered to be in a stationary state, the range of f-values we find at a given moment should be statistically representative of the values it can have over time, and it would be possible to extract conclusions that are valid for the whole duration of the stationary state. Therefore we took data from Godwin et al. (1983), and considered all the galaxies in Coma with photometry in the B and R bands, a total of 4075 objects. They cover a wide range of magnitude and size. The distribution of the f-parameter values is presented in Fig. 1. The median value of the distribution is -2.7 and, as it can be seen in the figure, there are no galaxies with f < -4.5.
In view of these results for Coma, it seems safe to adopt the formal criterion 4.5 to select what we will call isolated galaxies.
From the preceding considerations it is clear that the f cut-off value is probably too strict for situations where a candidate galaxy has only a few possible companions at most. Thus it is robust enough to cope with probable errors in the different observable parameters entering the definition and ensure that all the selected objects are actually isolated. From expression (3), it is simple to verify that errors of 20% in size and/or luminosity translate into errors of only a few tenths in f at most, still very far from critical values. Similarly, even a ratio between the projected distance and the pericenter distance as large as /b = 3 would produce an f-value greater than the
true value by 1.4 units, still far from critical values. Only for very eccentric orbits, and when the perturber is around the apocenter, our criterion would fail and could select
false isolated galaxies.
Another aspect to consider is the possibility of inducing biases in the family of the selected objects, given the dependency of f on the luminosity and size. A galaxy might have a different probability of being taken as isolated for a fixed population of possible companions. However, given a direct relation
between size and luminosity, we expect only a small net effect on f. Thus, considering
,
the difference in the f-values produced by a given perturber on galaxies with luminosities of the ratio 1/1.5 would amount to only 0.17, well inside the uncertainties in
M/L or any other parameter, and unable to approach critical values.
Given the preceding considerations we do not expect strong biases in the family of selected isolated galaxies.
Karachentseva (1973) considered a galaxy of diameter
as isolated when there were no companions with size,
,
between 1/4 and
,
within
.
To compare this with our criteria we have to assume that the luminosity is proportional to some power of the size, say
.
It is easy to verify that both criteria are similar. However, Karachentseva's criterion does not exclude the possibility of small, faint perturbers that could have some effect if they are close enough to the primary galaxy.
Márquez & Moles (1996) defined a galaxy as isolated if there are no companions within a projected radius of 0.5 Mpc, and with a relative redshift less than 500 km s-1. They also made a visual inspection of the POSS images to search for faint companions. Applying the f-value criterion to their data, we find that over 90% of the galaxies considered isolated by Márquez & Moles (1996) are also isolated using our criterion.
Vettolani et al. (1986) considered as isolated the galaxies without companions with
14.5, within a radius that varies with the distance to the galaxy to keep constant the probability of finding a galaxy in a given volume. The work was complemented with a search for fainter companions in the POSS plates, without a clearly stated objective criterion. We found that 15 out of the 43 galaxies in their sample have faint companions. We applied our f-parameter selection method to the other 28 galaxies, to find that only 2 of them would be considered as isolated with our criterion. This is a clear illustration of the problems that can be encountered when the difference between field and isolated galaxies is not clearly stated.
The starting point of our search was the CfA catalog of galaxies (Huchra et al. 2000). Our aim was to build a volume-limited, statistically meaningful sample of isolated spiral galaxies. To that end we first selected all the galaxies classified as disk galaxies (Spiral and Lenticular), with
km s-1. Only objects at high galactic latitudes,
,
were retained, to avoid problems with the extinction correction. Finally we considered only objects with declinations north of
.
1706 galaxies satisfy all these conditions. The properties of these galaxies were extracted from the LEDA database (Paturel et al. 1997). The distances were calculated using the LEDA kinematical distance modulus, corrected for extinction and Virgocentric flow.
Each galaxy was then searched for companions in the same LEDA catalog, complete to m = 18. The identification of the CfA objects with LEDA objects is not always straightforward since offsets in the coordinates up to 1' are not infrequent. When there was a possibility of misidentification we decided after visual inspection. Once all the CfA objects were identified in LEDA, we started the search for companions. The searching field was limited to that defined by the maximum distance at which a bright (massive) galaxy with M = -23 would produce a value of f=-4.5. Special care was taken to avoid confusion with extended objects that are not galaxies, and with double or distorted star images that were taken as galaxies in the preliminary version of the catalog we used.
We also imposed two more restrictions, on size and luminosity, to eliminate as many background objects as possible. The suspected companions were retained only if, at the distance of the parent galaxy, they would be larger than 2 kpc in diameter, and brighter than
.
For some faint galaxies present in the
search field no magnitudes were listed in the LEDA catalog. In these cases we calculated the apparent magnitude that those objects would have to produce f =-4.5, and we compared it with the estimation from visual inspection. Only companions found brighter than that value were retained. Using those restrictions we could reject most of the possible companions. For the doubtful cases the central galaxy was taken as perturbed. In a final step we discarded all the companions for which the (known) redshift is different from that of the primary galaxy by more than 500 km s-1. The f values for all the possible perturbers within the search volume were computed, and only those with f > -4.5 and satisfying the conditions on size and luminosity were finally taken as possible perturbers. The above selection process reduced the list of candidate galaxies to 329.
We then examined the DSS data looking for the presence of possible perturbers with
.
The process was only applied to the volume where those faint galaxies would still produce
.
The size and magnitude of all the possible perturbers were measured, and the size and luminosity criteria applied. More than 100 galaxies were found to have companions. At the end of the process a list of 203 isolated S and S0 galaxies was produced. This represents less than 12% of the initial sample. We insist that the list is not complete since all the galaxies with faint companions (
and
)
without known redshift were discarded. Besides that catalogue of isolated galaxies we selected another sample of non-isolated galaxies containing systems having companions with f > -2, and
km s-1. A total of 130 objects were extracted from the original sample. This sample will be used as a comparison for the properties of isolated galaxies. In the text, we shall refer to this sample as perturbed galaxies.

The database we used for the properties of the galaxies is the LEDA Catalogue. The identification and main properties of the isolated and perturbed galaxies are presented in Tables 1 and 2 respectively.
The data presented in these tables have been extracted from various sources, as described in the following. To standardize the information contained in our catalogue we extracted from the LEDA (Paturel et al. 1997) catalogue for each galaxy: PGC number, morphological type code t, the geometrical parameters at the 25 mag arcsec2 isophote log D25 and log r25, the corrected colors (U-B)0 and (B-V)0. the mean surface brightness at the same isophote ,
the kinematical parameters W20 (the 21-cm line width at 20% of the peak), log
(velocity dispersion), log
(the maximun rotational velocity), the redshift cz, the kinematic distance modulus
,
the blue corrected absolute magnitude
,
the far infrared magnitude
and the 21-cm line magnitude m21. The distance moduli are mainly derived from redshifts, corrected for Virgocentric inflow and adopting H0 = 70 km s-1 Mpc-1. When redshift was not available, we used the photometric distance modulus, if present in LEDA. The absolute values were calculated using these distance moduli. The entry coded as FIR-B in Table 1 corresponds to
.
Information lacking in LEDA for some galaxies was completed using the ADS bibliographic archive, the NED database or the SIMBAD service of the Strasbourg Centre of Données Stellaires (CDS), as indicated in the references of Table 1. They are:
The first aspect we considered was the distribution of the galaxies in both samples by morphological types (Fig. 2). The differences between the isolated and perturbed galaxy distributions are apparent. Given the clear non-normality of the distributions, we applied the Mann-Whitney U-test. The results indicate that the two distributions are different with a significance level >99.5%. The largest differences are found for Sc galaxies, that are more abundant among isolated galaxies (in agreement with earlier results by Márquez 1994; Márquez & Moles 1996; Márquez et al. 1999), and for S0 galaxies, that are more abundant among perturbed galaxies (see also Table 3).

To compare all the other properties of isolated and perturbed galaxies we grouped them into three morphological categories, S0 (
), early Sp (
)
and late Sp (t > 3.5).
It appears that barred galaxies are far more abundant (about twice) among perturbed galaxies. The difference is very marked for Lenticular and early Sp types, whereas there is no difference for late Sp galaxies (see Table 3). We also compared all the other catalogued properties of the two samples. The differences were tested with the Mann-Whitney U-test. We found that the two samples are different at a highly significant level (>99.5%) in all the main catalogued properties, including the absolute blue magnitude, ,
the infrared luminosity normalized to the B luminosity,
,
the size, D25, the color indexes (U-B) and (B-V), the mean surface brightness within the isophote 25,
,
the maximum velocity rotation of the gas,
,
the stellar central velocity dispersion,
,
and the 21-cm line width at 20% of the peak, W20. In Table 3 we give the median values of those properties for the different families.
The only property that appears to be similar for both samples is the amount of atomic gas as measured by
.
Looking at the different morphological bin there is a hint of a possible difference for lenticular galaxies.
It can be seen that the isolated galaxies are smaller, less luminous and bluer than the perturbed systems. We also notice the consistency of the results regarding the dynamical variables. ,
and W20 are smaller for the isolated galaxies. They also present lower FIR luminosity and molecular gas content. Notice that the same trend is seen in all the morphological bins we considered, even if the largest and more significant differences are found in most cases for the lenticular and early Sp galaxies.
Since the content of molecular gas is not given in LEDA we searched the literature using the same references and approach as Bettoni et al. (2003, the references are given in the Notes of Tables 1 and 2). We found data for only 21 isolated and 20 perturbed galaxies. We found that the perturbed galaxies have
higher
values, the difference being statistically significant at >99.5%. Notice that the difference arise only in the late SP morphological bin.
We analyzed the relation between global structural parameters. We found that both families satisfy the same Luminosity-Size relation (Fig. 3). We notice the almost absence of bright and large isolated galaxies, together with the almost absence of small and faint perturbed galaxies. This tendency cannot be due to the selection criteria, based on f values, and depending on sizes and luminosity as in Eq. (3). More massive and less extended systems are less subject to perturbations by the surrounding galaxies. One may expect that galaxies selected on the basis of a lower f could be biased toward smaller but brighter systems. On the contrary, isolated galaxies in our sample appear smaller, i.e. producing smaller f-values, but fainter, i.e. producing higher f-values.
In Fig. 4 we present the M versus L relation. The masses have been estimated using a central, point-like mass model, with
(v, from LEDA, in km s-1 and R25 in kpc). It can be seen in the figure that both families, isolated and perturbed galaxies, define very approximately the same relation, and share an important region in the diagram. The differences arise because there are no isolated galaxies with high mass (and luminosity), whereas there are no perturbed galaxies with low mass (and luminosity).

The Tully-Fisher relation for S galaxies in both samples is presented in Fig. 5. Even if both families follow the standard TF relation (Tully & Pierce 2000), the scatter is important and no conclusion about possible differences can be extracted before more homogeneous and accurate data are available. Apparently the presence of bars does not have any influence on the position of a galaxy in the T-F diagram, in agreement with the results reported by Courteau et al. (2003).

We used a well-defined, physically meaningful criterion to define isolated galaxies.
We performed a search for isolated galaxies using as the parameter the logarithmic
ratio f between the internal and tidal forces at the outskirts of a given galaxy.
The adopted limit, f < -4.5, was checked with results from numerical simulations
(Byrd & Howard 1992), and with data from the Coma Cluster. Similarly, a sample of perturbed galaxies was defined comprising galaxies with confirmed companions satisfying 2.
Comparison of the properties of the galaxies in both samples was made using the Mann-Whitney U-test. The first result to notice is the significant differences in morphological types, with Sc types being more abundant among isolated galaxies, whereas S0 galaxies are significantly more abundant among perturbed systems. We also found that barred galaxies are more frequent (about twice) among perturbed than among isolated galaxies except for late type Spiral galaxies.
They also differ in all the properties we have examined, except in atomic gas content, with similar values of the ratio
/
.
The isolated galaxies appear to be smaller and fainter, with bluer color indices. They also have less molecular gas and smaller FIR luminosity per unit of blue luminosity. The
dynamical parameters are also consistently smaller for isolated galaxies. Even if the differences are appreciable for all the families (S0, early Sp and late Sp), the biggest differences are for S0 and early Sp. The exception is in molecular gas content, for which the maximum difference is found for late-type Sp galaxies.
The M-L and M-size relations consistently show the absence of large, luminous and massive systems among the isolated galaxies. Moreover, we also found the almost complete absence of perturbed systems with small sizes, low luminosities and low masses. We also found that barred galaxies do not occupy a particular region of the T-F diagram.
In view of these results it is tempting to consider the differences as arising from the different evolutionary conditions. Our results indicate that the gravitational interaction in aggregates would produce evolution from late Spiral, relatively faint and low mass galaxies, toward earlier more luminous and massive Spiral and Lenticular types. This would also favor the formation of bars in early-type Spirals and Lenticulars. However, the relations between global parameters are similar for both families, even if they tend to occupy different regions in the corresponding plots (see Figs. 2-4)
Since the isolated galaxies would not have had the opportunity
to accrete other systems and grow in the way the hierarchical models predict, they would still be similar today to the high redshift systems supposed to be the building blocks for the formation of larger galaxies. This view is consistent with the results reported by Ferguson et al. (2003) showing that the sizes of galaxies at
are smaller than nearby luminous galaxies. If, as it is generally assumed, cannibalism and accretion in the early phases of galaxy evolution are important to fix the final global properties such as size, luminosity and mass, then present day isolated galaxies would be the left-over fragments in that early process of galaxy formation.
