supermassive (comparative more supermassive, superlative most supermassive)
Extremely massive; of extraordinary mass.
After being brought together by a galaxy merger, when the supermassive black holes are very small separations, the gravitational waves that they emit carry away energy and enable the black holes to merge. Source: Internet
And Hubble is credited with helping astronomers realize that supermassive black holes are ubiquitous with centers of giant galaxies. Source: Internet
De Rosa is the lead author of a review paper published in the journal New Astronomy Reviews that looks both the history of our search for supermassive black hole binaries and puts forward a road map for future discovery of such events. Source: Internet
Do they remain in a binary, or do they combine to form an even larger supermassive black hole? Source: Internet
Consequently, the physics of matter forming a supermassive black hole is much better understood and the possible alternative explanations for supermassive black hole observations are much more mundane. Source: Internet
A tidal disruption event of this sort is when a star interacts with a supermassive black hole shredding the star, and in some cases creating a relativistic jet which produces bright emission of gamma ray radiation. Source: Internet
