As gas falls towards a super-massive black hole its gravitational potential energy can be converted to heat and light, in some instances producing the most powerful sustained energy sources in the ...

From their search the team identified an astonishing 2,500 candidate dwarf galaxies hosting an active galactic nucleus (AGN ... black hole candidates, arranged in increasing order of stellar ...

In the modern universe, for galaxies close to our own Milky Way, supermassive black holes tend to have masses equal to around 0.01% of the stellar mass of their host galaxy. Thus, for every 10,000 ...

Intermediate mass black holes are so fascinating to scientists because they seem to exist within the vast mass gap between stellar mass black holes, which have masses up to 1,000 times that of the ...

In stellar clusters - groups of stars that can contain as few as a dozen to as many as millions - binary black holes can collide with massive stars. This collision can cause an explosion ...
