Description
In this work, we measure and model the galaxy number density radial profiles of eFEDS clusters using HSC-SSP galaxies. The eFEDS clusters have redshift $< 1.31$ and virial masses $\mathrm{∼10^{14} M_\odot/h}$. We divide the cluster sample into 26 subsamples based on redshift and virial mass.
For each subsample, we observe the mean galaxy number density radial profile within a radius of 3 Mpc/h. These profiles are then modeled using a projected NFW profile.
From this analysis, we obtain galaxy number density radial profile as a function of redshift and virial mass. This enables us to predict the radial profile of cluster galaxies given the cluster redshift and virial mass.
