| dc.description.abstract | We investigate the relationship between the environment and the galaxy main sequence (the relationship between stellar mass
and star formation rate), as well as the relationship between the environment and radio luminosity (P1.4 GHz), to shed new light on
the effects of the environment on galaxies. We use the VLA-COSMOS 3-GHz catalogue, which consists of star-forming galaxies
and quiescent galaxies (active galactic nuclei) in three different environments (field, filament, cluster) and for three different
galaxy types (satellite, central, isolated). We perform for the first time a comparative analysis of the distribution of star-forming
galaxies with respect to the main-sequence consensus region from the literature, taking into account galaxy environment and
using radio observations at 0.1 ≤ z ≤ 1.2. Our results corroborate that the star formation rate is declining with cosmic time, which
is consistent with the literature. We find that the slope of the main sequence for different z and M∗ bins is shallower than the
main-sequence consensus, with a gradual evolution towards higher redshift bins, irrespective of environment. We see no trends
for star formation rate in either environment or galaxy type, given the large errors. In addition, we note that the environment
does not seem to be the cause of the flattening of the main sequence at high stellar masses for our sample. | en_US |
