The distribution of dark matter and intracluster gas in galaxy clusters
We present the temperature radial profiles of intracluster gas, and the radial profiles of density and mass for dark matter and intracluster gas for five galaxy clusters: Abell 1413, Abell 1204, Abell 2744, Abell 223 and CL 0024+17 observed by Chandra X-ray Observatory. These profiles were obtained...

We present the temperature radial profiles of intracluster gas, and the radial profiles of density and mass for dark matter and intracluster gas for five galaxy clusters: Abell 1413, Abell 1204, Abell 2744, Abell 223 and CL 0024+17 observed by Chandra X-ray Observatory. These profiles were obtained based on the well-established fact, that the X-ray observed surface brightness of clusters are described well with the Navarro-Frenk-White density profile of the underlying dark matter distribution. We have found that density and mass profiles for all considered clusters have the same shape. Temperatures, masses and densities of these clusters lie within the ranges 5−10 keV, ∼ 10¹⁴ − 10¹⁵ Mꙩ and ∼ 10⁻²³ − 10⁻²⁵ kg/m3 respectively. We also determined the values of R₂₀₀ and M₂₀₀ for the clusters and estimated the fraction of gas and dark matter in total mass of each cluster to be ∼ 10 − 20% and ∼ 80 − 90% respectively. |
