Abstract:

We have carried out a number of studies to reveal radio properties of active galaxies, namely AGN and Starbursts. A major work was related to the cross-correlation of NVSS and FIRST radio catalogues and revelation of variable radio sources. Most probably, most of them are extragalactic ones; AGN and Starbursts. We have carried out spectroscopic classification of 6301 of these objects and revealed many Seyferts, LINERs and Starbursts. We have also studied radio properties of VCV-13 AGN, Markarian galaxies and Blazars. One of the aims of our studies is to establish the radio/opt flux ratio limit between normal galaxies detected in radio and radio loud active galaxies. The ultimate goal of these studies is to combine results obtained from radio studies and derived radio properties of active galaxies with gammaray, X-ray, UV, optical, IR and submm/mm to have the overall multiwavelength understanding on these objects.

General note:

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
