A quasar (/ ˈkweɪzɑːr / KWAY-zar) is an extremely luminous active galactic nucleus (AGN). It is sometimes known as a quasi-stellar object, abbreviated QSO. The emission from an AGN is powered by accretion onto a supermassive black hole with a mass ranging from millions to tens of billions of solar masses, surrounded by a gaseous accretion disc.

Az AGN -ek, blazárok és kvazárok fénye folyamatosan ingadozik, napos és éves, valamint évtizedes és évszázados időskálán is fényességváltozásokat mutatva. Ritkán előfordul, hogy egy kvazár kitörést produkál: hirtelen felfényesedik. A következő táblázat néhány ismertebb kvazár adatait tartalmazza.

Artist's conception of a powerful magnetar in a star cluster. A magnetar is a type of neutron star with an extremely powerful magnetic field (~10 9 to 10 11 T, ~10 13 to 10 15 G). [1] The magnetic-field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays. [2]

3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo. It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen from Earth, with an apparent visual magnitude of 12.9. [2] . The derived distance to this object is 749 megaparsecs (2.4 billion light-years).

Mar 16, 1998 · The first quasars were discovered in the early 1960s, when astronomers measured their very strong radio emissions. Scientists were subsequently surprised to see faint blue star-like points of light, rather than galaxies, when they looked at the same parts of space with optical telescopes.

В упрощенном виде можно сказать, что квазар это объект похожий на звезду размерами и наблюдаемый в оптическом диапазоне как звезда, но в то же время массой и мощностью радиоизлучения, во много раз превышающие любые звезды. Какими особенностями обладают квазары?

Možete li mi objasniti značenje pojmova kvazar i pulsar? Kvazari su objekti koji se astronomima pričinjavaju kao zvijezde (točke na fotografskoj ploči), ali su zapravo galaksije. Ime kvazar dolazi od engleskog "QUASi-stellAR object - QUASAR" - "objekt-kao-zvijezda".

Jan 20, 2021 · Najudaljeniji poznati kvazar pokreće najranija poznata supermasivna crna rupa, čija je težina 1,6 milijardi puta veća od mase Sunca. Ovaj potpuno formirani daleki kvazar, star više od 13 milijardi godina, ujedno je i najraniji do sada otkriven
