X-ray study of the merging cluster of galaxies AS0592
Abstract
In this talk, I will present the results of our study of the AS0592 massive cluster by using 100 ks Chandra observations. AS0592 is a binary merger, at redshift of 0.22, with a global gas temperature of 9.7 keV. The two merging components are clearly visible as surface brightness peaks in the X-ray image. The primary system harbors a strong cool core (kT 4 keV), which shows signs of sloshing induced by the merger event. We detected other merging signatures such as the bullet-like morphology of the secondary, the shock front found in the vicinity of secondary and a central region of dense gas with significantly higher temperature compared to the ambient medium. I will discuss the thermodynamic properties of the AS0592 cluster and how the observed merging characteristics were used to constrain a merging scenario for this system.
