Active and Passive Galaxies in Deep ROSAT Surveys
Abstract
ROSAT deep survey X-ray sources have been identified with active galaxies (Active Galactic Nuclei and Narrow Emission-Line galaxies) and also with early-type, ``passive galaxies''. In this paper we discuss preliminary results of the galaxy content, both early-type and emission-line galaxies, of 5 ROSAT fields.
