Abstract

We present R-band galaxy luminosity functions (GLFs) from a spectroscopic sample of six nearby rich galaxy clusters. In addition to individual cluster GLFs, extending to, in one case, MR = -14, we also present composite GLFs for cluster and field galaxies to MR = -17. All six cluster samples are consistent with the composite GLF, but there is evidence that the GLF of the quiescent population in clusters is not universal. Furthermore, the GLF of quiescent galaxies is significantly steeper in clusters than in the field. The overall GLF in clusters is consistent with that of field galaxies, except for the luminous tip, which is enhanced in clusters versus the field.
