... that around 1 - 2 billion years ago, a merger between two galaxies – each with central, massive black holes – took place. As the two black holes did not have the same mass and rotation rate, gravitational waves created as the...
... named LB-1 by the researchers. The discovery is reported in the latest issue of Nature. The discovery came as a big surprise. "Black holes of such mass should not even exist in our Galaxy, according to most of the current models of stellar evolution...
... rest of the galaxy put together. It is believed that this outpouring of radiation is a result of the accretion of matter by a supermassive black hole at the centre of its host galaxy and as the energy is dispersed, it heats and dispels the gas that...
...not able to escape from their cores due to the tremendous amount of gravity the black hole creates. Instead the primary method of detecting a black hole is through observations of radio or X-ray emissions coming from hot material around them. However...
... characteristics at very high precision. STIS was integral to effectively observing the low-luminosity region around the black hole, blocking out the galaxy’s brilliant light. The astronomers initially selected this galaxy to validate accepted models...
...from Moscow State University have found a new way to estimate the mass of elusive supermassive black holes located outside of the Milky Way. Black holes are notoriously difficult; difficult to find and difficult to study. In the past researchers have...
