Marat Arakelian
Marat Arsen Arakelian ( hy, Մարատ Արսենի Առաքելյան) () (15 January 1929 – 20 January 1983) was an 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” (named Arakelian galaxies, Akn), 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. Early life and education Arakelian was born in Goris, Syunik Province in the Armenian Soviet Socialist Republic, a Soviet republic (now the Republic of Armenia). He attended the Yerevan State University (YSU) in the Physical-Mathematical Department and graduated in 1951. He was among the first YSU students specialized in astrophysics. Arakelian was assigned to the Byurakan Astrophysical Observatory (BAO), where he worked first as assistant astronomer, and l ...

Goris
Goris ( hy, Գորիս) is a town and the centre of the urban community of Goris, in Syunik Province at the south of Armenia. Located in the valley of the Goris (or Vararak) River, it is 254 km from the Armenian capital Yerevan and 67 km from the provincial capital Kapan. Goris is the second-largest city in Syunik in terms of population. During the 2011 census, it had a population of 20,591, down from 23,261 reported in the 2001 census. However, as per the 2016 official estimate, the population of Goris was 20,300. Goris is the seat of the Diocese of Syunik of the Armenian Apostolic Church. Goris is considered one of the most important historical and cultural sites of Armenia. It is often regarded as the cultural center of Syunik. Because of this, it is a favored tourist destination for both local and foreign travelers and has a large number of hotels and inns. Following the administrative reforms in 2016, the community of Goris was enlarged to include the surrounding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armenian Soviet Socialist Republic
The Armenian Soviet Socialist Republic,; russian: Армянская Советская Социалистическая Республика, translit=Armyanskaya Sovetskaya Sotsialisticheskaya Respublika) also commonly referred to as Soviet Armenia or Armenia, ; rus, Армения, r=Armeniya, p=ɐrˈmʲenʲɪjə) was one of the constituent republics of the Soviet Union in December 1922 located in the South Caucasus region of Eurasia. It was established in December 1920, when the Soviets took over control of the short-lived First Republic of Armenia, and lasted until 1991. Historians sometimes refer to it as the Second Republic of Armenia, following the demise of the First Republic. As part of the Soviet Union, the Armenian SSR transformed from a largely agricultural hinterland to an important industrial production center, while its population almost quadrupled from around 880,000 in 1926 to 3.3 million in 1989 due to natural growth and large-scale influx of Armenian genoci ...

People From Goris
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Byurakan Astrophysical Observatory
The Byurakan Astrophysical Observatory, or Byurakan Observatory is an astronomical observatory owned and operated by the Armenian Academy of Sciences. It is located on the slope of Mount Aragats in the village of Byurakan in Armenia. History Founded in 1946 by Viktor Hambardzumyan, it was one of the main astronomy centers of the USSR. The buildings were designed by architect Samvel Safarian. The hotel, central building and structures are for astronomical instruments. The observatory has discovered special star clusters — stellar associations (1947), more than 1,000 flare stars, dozens of supernovae, hundreds of Herbig–Haro objects and cometary nebulae, hundreds of galaxies. The first conference was held in November 1951 on the topic of stellar associations. On 19 September 1956 a major meeting on non-stable stars was held. It has been the site of two major conferences on SETI, and is recognised as the regional center for astronomical research. Directors included V.A. Ambart ...

Active Galactic Nucleus
An active galactic nucleus (AGN) is a compact region at the center of a galaxy that has a much-higher-than-normal luminosity over at least some portion of the electromagnetic spectrum with characteristics indicating that the luminosity is not produced by stars. Such excess non-stellar emission has been observed in the radio, microwave, infrared, optical, ultra-violet, X-ray and gamma ray wavebands. A galaxy hosting an AGN is called an "active galaxy". The non-stellar radiation from an AGN is theorized to result from the accretion of matter by a supermassive black hole at the center of its host galaxy. Active galactic nuclei are the most luminous persistent sources of electromagnetic radiation in the universe, and as such can be used as a means of discovering distant objects; their evolution as a function of cosmic time also puts constraints on models of the cosmos. The observed characteristics of an AGN depend on several properties such as the mass of the central black hole, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
