Supermassive black hole binary emits unexpected flares
SMRTR summary
A binary supermassive black hole system, AT 2021hdr, 1 billion light-years away in Cygnus, flares brightly every 60 to 90 days as the black holes orbit through a gas cloud, consuming 3-30% each cycle. This phenomenon was identified after ruling out other possibilities. The black holes are expected to merge in about 70,000 years, potentially providing new insights into such systems and their interactions with surrounding matter.
