REOBSERVATION OF MOST HIGHEST TEMPERATURE REGION IN COMA.


ABSTRACT

Coma cluster of galaxies was thought to be one of the dynamically well relaxed cluster. But recent our analysys show this cluster is just after merging. We suggest reobservation of edge of coma cluster which is 40' in north-west away from cluster center and show most highest temperature in this cluster. This highest temperature is thought to be made by shock of cluster merging. Although there are some simulations of cluster merging, but the structure of shock region is not well known by observation until now. A further observation for 90ksec (already observed for 10ksec) will make us understand the structure of shock heating region which is the key structure of cluster merging.
