The Evolution of the Star Formation of zCOSMOS and SDSS galaxies at z<0.7 as a Function of Mass and Structural Parameters

TL;DR

This study compares the evolution of specific star formation rates in massive galaxies at z<0.7, analyzing how they relate to structural parameters like surface mass density and Sersic index, using data from zCOSMOS and SDSS.

Contribution

It provides a comparative analysis of galaxy star formation evolution as a function of structural parameters at low redshift, using a large, consistent galaxy sample.

Findings

Star formation rates vary with surface mass density.

Structural parameters influence galaxy evolution.

Comparison between high-z and local galaxy samples.

Abstract

We present in these proceedings some preliminary results we have obtained studying the evolution of the specific star formation rate as a function of surface mass density and Sersic indices at z<0.7. These results are based on the consistent comparison of the properties of ~ 650 massive zCOSMOS galaxies in a mass-complete sample at 0.5<z<0.7 with a mass-complete sample of ~ 21500 SDSS local galaxies.
