1992ApJ...397..438R HIGH-ENERGY X EMISSION FROM THE COMA CLUSTER YOEL REPHAELI Center for Astrophysics and Space Sciences, University of California at San Diego, La Jolla, CA 92093 AND OLEG GOLDSHMIDT Raymond and Beverly Sackler Faculty of Exact Sciences, School of Physics and Astronomy, Tel Aviv University, Tel Aviv, 69978, Israel Received 1991 December 9; accepted 1992 April 6 ABSTRACT A detailed assessment is given of conflicting high-energy X measurements of the Coma cluster region. Various considerations lead to the conclusion that the recent detection of intense emission in the band 18-130 keV is very unlikely to be diffuse intracluster emission from the Coma cluster. Therefore, the detection of diffuse intracluster emission would require detector sensitivity better than a few x 10^-6^ cm^-2^ s^- 1^ keV' in the few tens of keV range. If the observed emission originates in the Seyfert galaxy X Comae, its implied X luminosity would make it one of the strongest currently known high-energy X sources.
