Evolution of AGN Space Densities and the Fanaroff-Riley Dichotomy
Abstract
We focus on a comparison of the space densities of FR I and FR II extended radio sources at different epochs, and find that FR I and FR II sources show similar space density enhancements in various redshift ranges, possibly implying a common evolution.
