Description
We present the first measurement of the galaxy luminosity function (LF) at 1500 Å in the range 0.2≤ z≤ 1.2 based on Galaxy Evolution Explorer VIMOS-VLT Deep Survey observations (~ 1000 spectroscopic redshifts for galaxies with NUV≤ 24.5) and at higher z using existing data sets. Our main results are summarized as follows:(1) Luminosity evolution is observed with ΔM*~-2.0 mag between z= 0 and z= 1 and ΔM*~-1.0 mag between z= 1 and z= 3. This confirms that the star formation activity was significantly higher in the past.(2) The LF slopes vary in the range-1.2≥ α≥-1.65, with a marginally significant hint of increase at higher z.(3) We split the sample in three rest-frame (B-I) intervals, providing an approximate spectral type classification: Sb-Sd, Sd-Irr, and unobscured starbursts. We find that the bluest class evolves less strongly in luminosity than the two other classes. On the other hand, their number density …
