Assuming that the clusters are in hydrostatic equilibrium, masses can be estimated from temperature and density profiles of the clusters. In order to produce temperature and density profiles we performed data reduction, spectrum extraction, fitting of multiple observational spectra, and deprojection procedures. Density and temperature profiles were fitted with a single beta model and an exponential model respectively. We determined masses of the clusters enclosed by R2500, which is the radius where the density equals to 2500 times the critical density of the universe. We compare our results with other mass determinations employing different methods, i.e. Sunyaev Zeldovich Effect (SZE) and lensing, where available and found that within uncertainties they are in a good agreement.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Critical density,Density profile,Exponential models,Hydrostatic equilibrium,Mass determination,Sunyaev-Zeldovich effects,Temperature profiles,X ray satellites[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1742-6596/1354/1/012014[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
