Observation of reactions of super-hot gas by a CSIRO radio telescope verified the existence of the 1st noted “middleweight” black hole.
Called HLX-1 (“hyper-luminous X-ray source 1”), the black hole is situated in a galaxy known as ESO 243-49, around 300 million light-years apart.
Prior to discovery, astronomers had great data for just supermassive black holes - all those a million to a billion times the mass of the Sun-and “stellar mass” ones, 3 to 30 times the mass of the Sun.
“This is the 1st object that we are truly sure is an intermediate-mass black hole,” said Dr. Sean Farrell, an ARC Postdoctoral Fellow at the University of Sydney and a member of the research team, that involved astronomers from France, Australia, the UK and the USA.
