The exact nature of a quasar is unknown although they all seem to exist in close proximity to a black hole with the black hole providing large amounts of energy to the quasar. This is no ordinary black hole either, but an active one known as a quasar that’s surrounded by a super bright, highly energetic disk of swirling gas and dust. SS433 jet, for example, has a velocity of 0.23c. A quasar is a galaxy the gives off huge amounts of radiation, sometimes having a black hole at it's center. A black hole is a stellar remnant of a very massive star of more than 2 to 3 solar masses.
Massive central black holes in galaxies have the most powerful jets, but their structure and behaviours are similar to those of smaller galactic neutron stars and black holes.These SMBH systems are often called microquasars and show a large range of velocities. NGC 1889 was discovered in 2011 , and is suspected to have been a quasar in the past since it’s surrounded by a …
Let’s dig a little deeper. Even though the quasar is so far away and old, it is believed that the two black holes orbit round each other 1.2 years. It is thought the infall of matter into the supermassive black hole can result in very hot regions where huge energies are released, powering the quasar (i.e., producing the emitted light, etc.). Pic 1: A Black Hole exhibits Gravitational Lensing. Some people think the black hole ate all the dust and gas, leaving nothing for the quasar to have, and ceased to exist. Black holes and the quasar connection Quasar PG 0052+251 and its host galaxy. Thanks for A2A! What do quasars have to do with black holes? The central black hole is believed to be 150 million times the mass of the Sun and weigh over 4 million times the mass of the Sun.
In reality, the light comes from the accretion disk around a supermassive black hole. Located in E4 supergiant elliptical galaxy NGC 1889, or “Coma B”, this black hole retains 5,200 times more mass than the central black hole of the Milky Way galaxy! Quasars are extremely distant objects in our known universe. Blazars, like all active galactic nuclei (AGN), are thought to be ultimately powered by material falling onto a supermassive black hole at the center of the host galaxy. All known quasars are in the billions of light years away. They are the furthest objects away from our galaxy that can be seen. Astronomers using Hubble found that Markarian 231, the nearest galaxy that hosts a quasar, is powered by two central black holes furiously whirling about each other. How big are quasars compared to galaxies? The quasar 3C 273 appears starlike in this optical image taken by the Hubble Space Telescope.
