The luminosity function of field galaxies and its evolution since $\vec{z=1}$

We present the B -band luminosity function and comoving space and luminosity densities for a sample of 2779 I -band selected field galaxies based on multi-color data from the CADIS survey. The sample is complete down to $I_{815} = 22$ without correction and with completeness correction extends to $I_{815}=23.0$. By means of a new multi-color analysis the objects are classified according to their spectral energy distributions (SEDs) and their redshifts are determined with typical errors of $\delta z \le 0.03$. We have split our sample into four redshift bins between $z=0.1$ and $z=1.04$ and into three SED bins E-Sa, Sa-Sc and starbursting (emission line) galaxies. The evolution of the luminosity function is clearly differential with SED. The normalization $\phi^*$ of the luminosity function for the E-Sa galaxies decreases towards higher redshift, and we find evidence that the comoving galaxy space density decreases with redshift as well. In contrast, we find $\phi^*$ and the comoving space density increasing with redshift for the Sa-Sc galaxies. For the starburst galaxies we find a steepening of the luminosity function at the faint end and their comoving space density increases with redshift.
