Abstract
This paper presents a detailed study of X-ray emission from the cluster RXC J1252.5-3116, based on an analysis of the Chandra archival data. Here we present radial profiles and maps of X-ray surface-brightness, temperature, electron number density, entropy and pressure of RXC J1252.5-3116. We have also estimated the X-ray luminosity, gas mass, cooling time and mass deposition rate for the cluster. The cluster shows an extremely relaxed X-ray morphology and the radial profiles suggest a drop in the temperature of the central gas. We find an extremely small cool-core and a high mass deposition rate of 43 M⊙ per year. RXC J1252.5-3116 seems to host a possible cool core at its centre.
