Chandra observations of ten galaxy clusters
In the present study the X-ray properties of 10 galaxy clusters (CL0024+17, RXJ1347.5+1145, A223, A521, A611, A697, A907, A1204, A1413 and A2744) are analysed using the archival X-ray data of the Chandra observatory. The average temperature of each cluster is estimated to be ∼ 4 − 10 keV, and the ra...

In the present study the X-ray properties of 10 galaxy clusters (CL0024+17, RXJ1347.5+1145, A223, A521, A611, A697, A907, A1204, A1413 and A2744) are analysed using the archival X-ray data of the Chandra observatory. The average temperature of each cluster is estimated to be ∼ 4 − 10 keV, and the radial temperature profiles are reconstructed. Using the Navarro-Frenk-White (NFW) density pro le of the dark matter the density and mass
profiles for the dark matter and the hot diffuse gas, and also the total mass profiles are derived. The typical size of galaxy clusters and the density of the dark matter halo are estimated to be ∼ 0.1−2 Mpc and ∼ 10⁻²²−10⁻²⁴ kg/m³, respectively. The fraction of each component in the total cluster mass for the whole sample is found to be ∼ 80-90% for dark matter and ∼ 10 − 20% for intracluster gas, respectively. |
