Latest Supermassive black holes Stories
Astronomers suggest, in the Astrophysical Journal Letters, as galaxies formed in the early universe, they were accompanied by fireworks in the form of energy bursts.
NASA will host a news teleconference at 1 p.m. EDT, Wednesday, Aug. 29, to announce new discoveries from its Wide-field Infrared Survey Explorer (WISE).
Researchers from a Japanese university have discovered intermediate-mass black hole (IMBH) candidates at the center of the Milky Way.
Researchers from several American institutes and agencies have developed a new model showing how an elusive type of black hole can be formed in the gas surrounding their supermassive counterparts.
Observations with CSIRO's Australia Telescope Compact Array have confirmed that astronomers have found the first known "middleweight" black hole.
Astronomers have spotted the first known "middleweight" black hole, according to a publication in Science Express.
According to a post by the European Research Media Center, the black hole in the center of our galaxy is about to meet up with a giant gas cloud in 2013.
New evidence from NASA's Chandra X-ray Observatory challenges prevailing ideas about how supermassive black holes grow in the centers of galaxies.
Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...
Seyfert Galaxy -- Seyfert galaxies are spiral or irregular galaxies containing an extremely bright nucleus, most likely caused by a supermassive black hole, that can sometimes outshine the surrounding galaxy. The light from the central nucleus varies in less than a year, which implies that the emitting region must be less than one light year across. They are named for the astronomer Carl Seyfert, who studied them extensively in the 1940s. They are a subclass of active galactic nuclei....
Quasar -- A quasar (from quasi-stellar radio source) is an astronomical object that looks like a star in optical telescopes (i.e. it is a point source), but has a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law and that their redshift indicates that they are typically very distant from Earth; we observe them as they were several billions of years ago. Since we can see them despite their distance, they must emit more...
