13 mag 2024 · 3C 48. quasar, an astronomical object of very high luminosity found in the centres of some galaxies and powered by gas spiraling at high velocity into an extremely large black hole. The brightest quasars can outshine all of the star s in the galaxies in which they reside, which makes them visible even at distances of billions of light-year s.
Blazars are important topics of research in astronomy and high-energy astrophysics. Blazar research includes investigation of the properties of accretion disks and jets, the central supermassive black holes and surrounding host galaxies, and the emission of high-energy photons, cosmic rays, and neutrinos .
Main character (s) Wendell Vaughn. Quasar is the name of several fictional superheroes appearing in American comic books published by Marvel Comics. They are noted for having worn the Quantum Bands, advanced ancient alien technology that grants the wearer manipulation of quantum energy.
Apparent magnitude (V) 17.62 [1] Other designations. 2C 26, LEDA 2817473 [1] See also: Quasar, List of quasars. 3C 9 is a lobe-dominated quasar [1] [3] located in the constellation Pisces . In 1965, it was the most distant object discovered at the time of discovery. This was the first object with a redshift in excess of 2.
Superluminal motion. In astronomy, superluminal motion is the apparently faster-than-light motion seen in some radio galaxies, BL Lac objects, quasars, blazars and recently also in some galactic sources called microquasars. Bursts of energy moving out along the relativistic jets emitted from these objects can have a proper motion that appears ...
16 nov 2023 · Some of the largest known quasars are estimated to consume “matter equivalent to 600 Earths” every minute (Wikipedia.org). At this rate, average quasars are believed to live anywhere from a hundred million years to several billion years.
In astronomia, oggetto extragalattico di aspetto stellare, estremamente lontano e luminoso. Il nome q. fu inizialmente attribuito a sorgenti radio intense che avevano nel visibile un aspetto stellare. In seguito, però, si individuarono altri corpi, assai più numerosi, che non erano forti emettitori di onde radio, ma avevano le stesse ...
