We estimate the galaxy stellar mass function and stellar mass density for star-forming and quiescent galaxies with 0.210^(10.7-10.9) Msun, while the rapid evolution at the low mass end is explained by the evolution of the specific star formation rate. By deriving the global stellar mass density, we show that galaxies grow in mass twice as quickly at 1View original: http://arxiv.org/abs/1301.3157
