Another intermediate-mass black hole discovered at the centre of our galaxy


So far, only about ten intermediate-mass black holes have been discovered in the entire universe / The newly identified black hole causes surrounding stars in a cluster to move in an unexpectedly orderly way

Two conclusions can be drawn from this regular pattern: On the one hand, IRS 13 appears to interact with SgrA*, which leads to the orderly motion of the stars. This would be supported by the fact that the researchers were able to observe characteristic X-rays and ionized gas rotating at a speed of several 100 km/s in a ring around the suspected location of the intermediate-mass black hole. “IRS 13 appears to be an essential building block for the growth of our central black hole SgrA*,” said Florian Peißker, first author of the study.
