TEMPERATURE STRUCTURE IN ABELL-1367

We study the temperature structure of the rich cluster of galaxies Abe ll 1367 using two independent methods of correcting for the ASCA point -spread function. The results of the two methods are in excellent agre ement and give solid evidence of a strong and localized shock in the i ntracluster medium. Our analysis suggests that we are observing the me rger of two subclusters. We find that the lower luminosity subcluster, located to the northwest, has a higher temperature of 4.2 +/- 0.3 keV , compared to the more luminous southeast subcluster, whose temperatur e is 3.2 +/- 0.1 keV. An analysis of the ROSAT surface brightness prof iles of both subclusters is also presented. The data agree well with p redictions from numerical simulations of mergers between subcluster-si zed masses, in particular with early stages of the merger prior to the first core passage.
