Structural properties of the newly discovered dwarf galaxy dw1046+1244.
| dw1046+1244 | |
|---|---|
| RA (J2000) | 10:46:45.96 |
| Dec (J2000) | +12:44:59.5 |
| mF606W (mag) | 21.92 ± 0.14 |
| reff (arcsec) | 4.2 ± 0.6 |
| μeff, F606W (mag arcsec−2) | 27.0 ± 0.3 |
| MF606W (mag) | −8.1 ± 0.3 |
| rh (pc) | 210 ± 29 |
| L* (105 L⊙) | 1.5 ± 0.3 |
| M* (105 M⊙) | 2.3 ± 0.3 |
Notes. The parameters mF606W and reff have been corrected by −0.09 mag for systematic errors calculated in our artificial galaxy tests (see text). To estimate MF606W, rh, and L*, we adopted a distance of 10.2 Mpc, as measured for M96-DF6, and M* is based on a mass-to-light ratio of 2, which is typical for dwarf galaxies (e.g., Müller et al. 2021b).
