The letter, written by a team of British and French astronomers, does not state that they have found an intermediate mass black hole—one that could be termed just right—but that they have found an object where most other explanations fail to explain its behavior.More details at ARS Technica.
The object, 2XMM J011028.1-460421 or (more conveniently) HLX-1, is a source of ultraluminous X-rays near the spiral galaxy ESO 243-49. These X-rays have been postulated to be the product of an intermediate mass black hole, one between 100 and 10,000 solar masses, but to date no candidate object has been widely accepted.
Astronomers may have found first intermediate mass black hole
