Active Galactic Nuclei in the RASS

X-ray astronomy became topic of research in Hamburg with the launch of the ROSAT satellite in 1990. A larger effort undertaken is the identification of ROSAT sources on Schmidt plates of the Hamburg Quasar Survey. Other projects involve follow-up observations of selected X-ray sources with ROSAT and optical telescopes.
