Gravitational waves expel black hole from galaxy centre
... 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...

"Impossible" black hole found in our Galaxy
... 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...

Mass of black holes determines star formation history
... 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...

First inactive stellar-mass black hole found in a globular cluster
...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...

Hubble uncovers black hole that shouldn't exist
... 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...

A new way to 'weigh' extragalactic black holes
...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...
