Abstract:

We present the galaxy optical luminosity function for the redshift range0.05 < z < 0.75 from the AGN and Galaxy Evolution Survey, aspectroscopic survey of 7.6 deg2 in the Boötes field ofthe NOAO Deep Wide-Field Survey. Our statistical sample is composed of12,473 galaxies with known redshifts down to I = 20.4 (AB). Our resultsat low redshift are consistent with those from Sloan Digital Sky Survey;at higher redshift, we find strong evidence for evolution in theluminosity function, including differential evolution between blue andred galaxies. We find that the luminosity density evolves as (1 +z)(0.54 ± 0.64) for red galaxies and (1 + z)(1.64± 0.39) for blue galaxies.
