Abstract:

We measure the evolution of the stellar mass function (SMF) from z = 0-1using multi-wavelength imaging and spectroscopic redshifts from thePRism MUlti-object Survey (PRIMUS) and the Sloan Digital Sky Survey(SDSS). From PRIMUS we construct an i < 23 flux-limited sample of~40, 000 galaxies at z = 0.2-1.0 over five fields totaling ≈5.5deg2, and from the SDSS we select ~170, 000 galaxies at z =0.01-0.2 that we analyze consistently with respect to PRIMUS to minimizesystematic errors in our evolutionary measurements. We find that the SMFof all galaxies evolves relatively little since z = 1, although we do
