The Evolution of Galaxies and Active Galaxies with Cosmic Epoch

1998
Over recent years, there has been a deluge of data concerning changes with cosmic epoch of essentially all classes of extragalactic object. Evidence for strong evolutionary changes with cosmic epoch was first found in the 1950s and 1960s as a result of surveys of extragalactic radio sources and quasars.
