Description
We aim to measure the stellar mass content and luminosity function of 6,439 X-ray selected galaxy clusters from the all-sky RASS-MCMF catalog, using WISE W1 (3.4 μm) photometric data. Our sample spans a mass range of $10^{13}M_\odot \lesssim M \lesssim 10^{15}M_\odot$ and redshifts $0.05 <z_{cl}< 0.4$. We use the unWISE catalog with a limiting magnitude of W1 ≈ 20.45 mag.
In our work, we apply corrections for spatial masking and detection incompleteness during the photometric analysis. With these corrections, we measure the luminosity function of these clusters up to the limiting magnitude of the 50% completeness. In addition, we investigate the radial dependence of the luminosity function within galaxy clusters.
We will model the stellar mass content using stellar population synthesis (SPS) models based on the measured luminosity functions.
