Mysterious flashing seen near supermassive black hole. Astronomers have an idea what it is
A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?
Supermassive Black Hole Caught Doing Something Never Seen Before
Sgr A*, at the heart of the Milky Way and clocking in at 4.3 million solar masses, is the closest supermassive black hole we have access to. It's also on the quiescent end of the activity scale, which means we have a front row seat to small-scale black hole behavior that would be too faint to see were it taking place in another galaxy.
Mysterious black hole starts flashing – and scientists don’t know why
A mysterious black hole has started behaving even more strangely, scientists have said. The supermassive black hole has been sending out flashes that have increased in speed. The black hole is known as 1ES 1927+654,
Scientists use black-hole mergers to test symmetries of the universe
In an article published in Physical Review Letters on Thursday, scientists carried out an innovative study testing the existence of mirror asymmetries in our universe by studying the handedness of the gravitational-wave emission from black-hole mergers detected by Advanced LIGO and Virgo.
Feeding supermassive black holes may have ended the cosmic 'dark ages' billions of years ago
"Finding more supermassive black holes that are potentially hosting jets raises the question as to how these black holes grew so big in such a short timescale."
