X-Ray Emission as Evidence of Activity in Otherwise "normal" Galaxies
Abstract
The authors consider the normal galaxies selected in the Medium Sensitivity Survey and discuss the properties of the most X-ray luminous one. They show that this object, which has an optical spectrum lacking any evidence of nuclear activity and which has a radio luminosity typical of early type galaxies, is indeed a peculiar galaxy surrounded by a hot (>2 keV) halo extending out to a radius of 300 kpc, implying a total mass of ≡3×1013M_sun;.
