Study of a Cold Front in a Massive Cooling Flow Cluster of Galaxies with Strong Lensing
Abstract
Using the data contained in the Chandra archive we discovered a cold front in the atmosphere of the cluster of galaxies MS1455.0+2232. The importance of this finding is related to the fact that: i) it represents the biggest edge observed so far; ii) it lies in one of the most massive cooling flow clusters known; iii) the optical image of the cluster hosts a lensed arc inside the cold front sector. Moreover the X-ray and the lensig estimates show a discrepancy of a factor 1.8. It has been argued that cold fronts may both influence the development of cooling flows as well as to induce a mass bias that could explain point iii) above. We propose a deep Chandra follow-up of MS1455.0+2232 that will shade light on the above issues.
