  Abstract:
Canada-France-Hawaii Telescope Legacy Survey optical photometry has been used to study the galaxy luminosity functions (LFs) of 14 X-ray selected clusters from the XMM Large Scale Survey (XMM-LSS) survey. These are mostly groups and poor clusters, with masses (M500) in the range 0.6 to 19 � 1013Msolar and redshifts 0.05 <= z <= 0.61. Hence, these are some of the highest redshift X-ray selected groups to have been studied. Lower and upper colour cuts were used to determine cluster members. We derive individual LFs for all clusters as well as redshift-stacked and temperature-stacked LFs in three filters, g',r' and z', down to M = -14.5. All LFs were fitted by Schechter functions which constrained the faint-end slope ...
