Vigen Malumian

'''Vigen Malumian was an Armenian astrophysicist who specialised in radio galaxies and the radio characteristics of spiral galaxies. He was a prominent scientist at the Byurakan Observatory in Armenia, a professor at the Faculty of Physics at Yerevan State University, and a member of the BAO Scientific Board. Additionally, he was involved in the scientific council responsible for awarding degrees at the Observatory. Malumian was also a member of several international scientific organizations, including the International Astronomical Union, the European Astronomical Society (EAS), and the Armenian Astronomical Society.

Life and career

Malumian graduated in 1954 from the Faculty of Physics and Mathematics at Yerevan State University in Armenia. He began working at the Byurakan Astrophysical Observatory shortly thereafter. From 1955 to 1959, he studied in graduate school and defended his candidate dissertation at Yerevan State University in 1963. His dissertation, titled Results of Observations of Certain Galactic Radio Sources at 33 cm Using High-Resolution Radio Telescopes, was supervised by the renowned radio astronomer Semyon Emanuelovich Khaykin.
In 1991, Malumian was awarded a Doctorate of Physical and Mathematical Sciences at the Byurakan Astrophysical Observatory, following his research on Radio Emission from Moderately Active and Weak Radio Galaxies. His work focused on isolated and interacting galaxies, galaxy groups, radio galaxies, quasars, and other radio sources in multiple wavelength domains. Malumian authored more than 90 scientific papers, many of which were widely cited in international scientific literature. He presented his research at numerous international scientific conferences.
Malumian was also active within the IAU, where he participated in IAU Symposium 194. He held memberships in various IAU divisions, including Division B Facilities, Technologies, and Data Science, Commission 40 Radio Astronomy, and Division X Radio Astronomy.
Malumian died in Yerevan on 2 February 2013, at the age of 80.
