Notes. For M 82 we observed the north-eastern (NE) molecular lobe at an offset position (Δα,Δδ) = ( + 13.0′′, + 7.5′′) with respect to its dynamical centre.

(a)

Distances taken from the NASA/IPAC Extragalactic Database;

(b)

systemic local standard of rest (LSR) radial velocities following the optical convention, taken from SIMBAD;

(c)

source sizes and their corresponding spatial scales for the assumed distances;

(d)

star formation rate obtained from Walter et al. (2008) for M 83; Strickland et al. (2004) for NGC 253 and M 82; Schuster et al. (2007) for M 51; Esquej et al. (2014) for NGC 1068; Genzel et al. (1995) for NGC 7469; Anantharamaiah et al. (2000) for Arp 220; Taylor et al. (1999) for Mrk 231. We note that this parameter is only meant to give a rough idea of the activity, as it was calculated for different volumes in each galaxy. e Infrared luminosities taken from Sanders et al. (2003).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
