The luminosity function of the NoSOCS galaxy cluster sample.

Abstract (from CDS):
We find an indication that the dwarf-to-giant ratio decreases with increasing redshift, within 0.07 ≤ z < 0.2. We also measure a trend for the stronger suppression of faint galaxies (below M*+ 2) with increasing redshift in poor systems, with respect to more massive ones, indicating that the evolutionary stage of less-massive galaxies depends more critically on the environment.
Finally, we point out that the luminosity function is far from universal; hence, the uncertainties introduced by the different methods used to build a composite function may partially explain the variety of faint-end slopes reported in the literature, as well as, in some cases, the presence of a faint-end upturn.
