Vigen Malumian

Vigen Malumian is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Vigen Malumian rather than just read about it. In short: Vigen Malumian (Armenian: Վիգեն Հայկի Մալումյան) (Russian: Виген Гайкович Малумян) (11 March 1932 – 2 February 2013) 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 (BAO), a professor at the Faculty of Physics at Yerevan State University, and a member of the BAO Scientific Board.

Key takeaways

Vigen Malumian belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Vigen Malumian to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Vigen Malumian from memory before moving on to harder problems.

Reference excerpt

Vigen Malumian (Armenian: Վիգեն Հայկի Մալումյան) (Russian: Виген Гайкович Малумян) (11 March 1932 – 2 February 2013) 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 (BAO), 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 (IAU), the European Astronomical Society (EAS), and the Armenian Astronomical Society (ArAS).

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 (until 2013), and Division X Radio Astronomy (until 2012). Malumian died in Yerevan on 2 February 2013, at the age of 80.

Worked examples

Example 1 — a first encounter with Vigen Malumian

Start with the simplest possible case. Write down what Vigen Malumian claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Vigen Malumian before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Vigen Malumian ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Vigen Malumian

In research: Vigen Malumian appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Vigen Malumian in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Vigen Malumian is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1932 births, 2013 deaths, Armenian astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Vigen Malumian outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
