context_page_description: Marat Arsen Arakelian was a Armenian astronomer. Arakelian was a specialist in theoretical astrophysics and extragalactic astronomy. He is most noted for his catalog of “Galaxies of high surface brightness”, a list of 621 objects with surface brightness at least 22.0 magnitude from an area of 1 sq. arc second. The Arakelian catalog has become a source in the study of active galactic nuclei.
context_section_description: From 1957 to 1959, Arakelian combined his work with a senior teacher position at the Department of Astrophysics at Yerevan State University. Aralekian was a junior researcher and lectured at the Leningrad State University from 1960 to 1966. After being awarded the title of Associate Professor in 1966, Arakelian again joined the staff at Byurakan Astrophysical Observatory, combining his research with a position as lecturer at Yerevan. Together with L.V. Mirzoyan, A.T. Kalloghlian, and H.M. Tovmassian, he was the co-author of the textbook Astronomy for secondary schools (three editions in 1970, 1971, and 1973). In 1967, he became a senior researcher at the Byurakan Astrophysical Observatory. In 1977, Arakelian defended his second doctoral thesis "Spectral observations and statistics of galaxies with active nuclei" at Moscow State University (MSU) and became a Doctor of Sciences. In 1982, he was elected the Chair of the Department of Astrophysics and Theoretical Physics of the Armenian State Pedagogical University named after Khachatur Abovian. Arakelian wrote an extended review on “Clusters of galaxies” in the book Problems of Extragalactic Astronomy (1981).
  Prior to his death at the age of 54 on 20 January, 1983 in Moscow, Arakelian devoted himself to research, publishing over 80 articles.
