Isolated and group environment dependence of stellar mass and different star formation rates

Abstract

In this study, we explored the impact of isolated and group environments on stellar mass, star formation rate (SFR), and specific star formation rate (SSFR, i.e., the rate of star formation per unit stellar mass) using the galaxy dataset from the Sloan Digital Sky Survey Data Release 12 (SDSS DR12) for $z\lesssim 0.2$. To mitigate the Malmquist bias, we partitioned the entire dataset into fifteen subsamples with a redshift bin size of $\Delta z=0.01$ and examined the environmental dependencies of these properties within each redshift bin. A strong correlation between environment, stellar mass, SFR, and SSFR was observed across nearly all redshift bins. In the lower redshift bins $(z<0.1)$, the proportion of galaxies within the isolated environment exceeded that within the group environment. On the other hand, in the higher redshift bins $(z\ge 0.12)$, the isolated environment's galaxy fraction is found to be lower than that of the group environment. For the intermediate redshift bins $(0.1\le z<0.12)$, an approximately equal proportion of galaxies is observed in both isolated and group environments.
