Radio and X-Ray Emission in Early-Type Galaxies
Abstract
The radio and X-ray emission in nearby early type galaxies are compared. The results indicate that there is a correlation between the X-ray and the radio luminosities, although with a very large scatter. Part of this scatter might be reduced with better radio data, but most of it is probably intrinsic to the data, and indicates a rather complex relation between these two quantities. Sources with low radio luminosity could be effectively confined within the optical galaxy by the hot gas radiating in X-rays. For galaxies with Lr greater than 10 to the 29th ergs/s Hz confinement is no longer viable.
