We present surveys and related studies of active galaxies carried out at the NAS RA V.Ambartsumian Byurakan Astrophysical Observatory (BAO). This has been one of the main research subjects at BAO for many years since the mid-1950s, when Viktor Ambartsumian suggested the hypothesis of the activity of the galactic nuclei.

The joint catalogue of Active Galactic Nuclei selected from optical identifications of X-ray sources was created as a combination of two samples: Hamburg-ROSAT Catalogue (HRC) and Byurakan-Hamburg-ROSAT Catalogue (BHRC). Both are based on optical identifications of X-ray sources from ROSAT catalogues using low-dispersion spectra of Hamburg Quasar …
