(Phys.org)—A team of researchers working at the Astrophysical Institute of the Canary Islands has found evidence of a previously unknown structure in the accretion disk of a black hole that is part of an X-ray binary system. ...
(Phys.org) -- Last year, astronomers discovered a quiescent black hole in a distant galaxy that erupted after shredding and consuming a passing star. Now researchers have identified a distinctive X-ray signal observed in ...
