Unformatted text preview: 39 W between 10 MHz and 100 GHz. The radio emission is due to the synchrotron process . The observed structure in radio emission is determined by the interaction between twin jets and the external medium, modified by the effects of relativistic beaming . The host galaxies are almost exclusively large elliptical galaxies . Radio-loud active galaxies are interesting not only in themselves, but also because they can be detected at large distances, making them valuable tools for observational cosmology . Recently, much work has been done on the effects of these objects on the intergalactic medium , particularly in galaxy groups and clusters ....
