This research paper investigates the radial profiles of dark matter, intra-cluster gas mass, and galaxy mass within a composite of 59 rich galaxy clusters. The study reveals that the dark matter and galaxy mass profiles exhibit similar distributions, whereas the intra-cluster gas mass profile is found to be less centrally concentrated. These findings are then compared against the predictions of various cosmological models. The data was compiled and analyzed for the BDMH 2004 conference, focusing on Baryons in Dark Matter Halos, held in Novigrad, Croatia, from October 5th to 9th, 2004. The publication details are provided, including its origin from SISSA and a link to the full proceedings. This scientific abstract summarizes a key study in astrophysics concerning the distribution of matter in galaxy clusters and its implications for cosmological theories.

The relative distributions of Dark Matter and Baryons in Galxy Clusters

Using a composite of 59 rich galaxy clusters, we determine and compare the radial profiles of dark matter, intra-cluster gas mass, and mass in galaxies.
