This analysis was performed for clusters in the redshift range [0.1, 0.8] and in the mass range [10<SUP>13</SUP> M<SUB>⊙</SUB>, 10<SUP>15</SUP> M<SUB>⊙</SUB>]. <BR /> Methods: To compute LFs, we binned the luminosity distribution in magnitude and statistically subtracted the background. Then, we divided the cluster sample in bins of both redshift and richness/mass. We stacked LF counts in each 2D bin for the total, red, and blue galaxy populations; finally, we fitted the stacked LF with a Schechter function and studied the trend of its parameters with redshift and richness/mass. <BR /> Results: We found a passive evolution with z for the bright part of the LF for the red and total populations and no significant trends for the faint galaxies. The mass/richness dependence is clear for the density parameter Φ<SUB>⋆</SUB>, increasing with richness, and for the total population faint end, which is shallower in the rich clusters.STAMPAenArticle10.1051/0004-6361/2020392592-s2.0-85098127867http://arxiv.org/abs/2011.05131v1https://www.aanda.org/articles/aa/full_html/2021/01/aa39259-20/aa39259-20.html2021A&A...645A...9PFIS/05 - ASTRONOMIA E ASTROFISICA
