Supermassive Black Hole
"Supermassive Black Hole" is a song by British rock band Muse and is featured on their 2006 album, Black Holes and Revelations.
Supermassive Black Hole
As the name suggests, supermassive black holes contain between a million and a billion times more mass than a typical stellar black hole.

Supermassive Black Hole: A black hole that has a million or as much as a billion solar masses. Such huge black holes lurk at the centers of many active galaxies.

SUPERMASSIVE BLACK HOLE - Black holes that contain between a million and a billion times more mass than a typical stellar black hole.
Supermassive black holes at the hearts of active galaxies swallow large amounts of gas. During this feast they spill a lot of their "food," which is discharged in turbulent outbursts.
Supermassive black holes (SMBHs) exist at the very center of many galaxies, including our own Milky Way Galaxy. SMBHs usually weigh in on the order of millions or billions of times that of our Sun.

supermassive black hole A black hole with a mass much greater than the most massive stars (100 solar masses). The central regions of virtually every galaxy are thought to contain a supermassive black hole of a million solar masses or more.
Supermassive Black Hole
A black hole possessing as much mass as a million or a billion stars. Supermassive black holes reside in the centers of galaxies and are the engines that power active galactic nuclei and quasars.
Supermassive black holes containing millions to billions of solar masses could also form wherever a large number of stars are packed in a relatively small region of space, or by large amounts of mass falling into a "seed" black hole, ...
The supermassive black hole at the core of a galaxy rips apart a passing star and begins to ingest its hot gas in this artist's concept. An orbiting X-ray observatory watch this process take place in a galaxy about four billion light-years away.

Scientists think supermassive black holes formed at the same time as the galaxy they are in. The size of the supermassive black hole is related to the size and mass of the galaxy it is in.
Many galaxies have supermassive black holes at their centre. brightness A measure of the amount of electromagnetic radiation from a celestial object.
The energy is coming from an accretion disk of gas around a supermassive black hole at the nucleus of the galaxy. adaptive optics a technique that compensates for atmospheric turbulence by quickly adjusting the light path in the optics.

Motivated by such ideas, astronomers have recently searched the nuclei of nearby galaxies (including the Milky Way) for the presence of a "dead quasar" (a supermassive black hole that is presently producing little or no light).
Various astronomers have speculated that large volumes of interstellar gas collect and collapse into supermassive black holes at the centres of quasars and peculiar galaxies (e.g., galactic systems that appear to be exploding).
Some astrophysicists suggest that immense volumes of interstellar matter can collect and collapse into supermassive black holes, such as are found at the center of some galaxies.
This wouldn't be your garden variety black hole but a supermassive black hole with a mass perhaps a million times that of the sun. One of the arguments in favor of such a mass is the large velocities observed in the stars and gas at the center.
At the center of Messier 87 in the Virgo cluster lies a supermassive black hole of three THOUSAND million solar masses.
Our whole solar system, along with all the local stars you can see on a clear dark night, sit in one of our galaxy's spiral arms, known as the Orion arm, as they orbit the supermassive black hole in the dense star cluster at the center of our galaxy ...
One of the most popular hypothesis is the supermassive black hole theory. When materials surrounding the black hole fall into it, large amount of energy is released. Galaxy collision may create the supermassive black hole at the center.
It is a large galaxy with an active nucleus harbouring a supermassive black hole. It has near-perfect spiral arms. It was discovered by the German astronomer Johann Elert Bode in 1774.
In the center of many galaxies there may rest supermassive Black Holes. Around these Black Holes gigantic discs of matter falling onto them form.
Definition: microquasar: Microquasars are stellar mass black holes, that display characteristics of the supermassive black holes found at the centers of some galaxies. For instance, they have radio jets - something not every black hole has.
The article announcing the discovery (with scientific details): A Star in a 15.2 year orbit around the supermassive black hole at the center of the Milky Way, by R. Schödel et al (22 co-authors), Nature, vol. 419, p. 694-6, 17 October 2002.
The brightness of an active galactic nucleus is thought to come from an accretion disk around a supermassive black hole.
This discovery, as well as data gathered on other possible black holes, has provided stimuli not only for the belief that supermassive black holes exist at the core of galaxies, but for understanding other aspects of these entities, ...
The composition is unknown; it might consist of very low mass stars or supermassive black holes, but big-bang nucleosynthesis calculations limit the amount of such baryonic matter to a small fraction of the critical mass density.
The behavior of s(r) at small radii contains information on the degree of central mass concentration (is there a supermassive black hole?), but even here anisotropic velocity dispersion can complicate the analysis, ...
Since then, a number of star systems have been discovered where one of the stars is so massive and compact that theory cannot reasonably describe it as anything but a black hole. Supermassive black holes with the mass of millions or even hundreds of ...
