Astronomers capture unprecedented view of supermassive black hole in action
Active galactic nuclei are supermassive black holes at the center of certain galaxies. As matter falls into these black holes, enormous amounts of energy are released, making active galactic nuclei, or AGN,
Supermassive black hole births jets, hosts orbiting white dwarf, all while astronomers watch
Since 2018, we've seen 1ES 1927+654 generate jets in real time and found it may have a lone white dwarf orbiting near the point of no return.
Astronomers Found Strange, Accelerating X-Ray Pulses Coming From a Black Hole. They Might Be a Sign of an Orbiting White Dwarf
The dense stellar remnant would, if confirmed, be the closest known object to any black hole, according to preliminary research
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?
Mysterious x-ray flashes are accelerating in a black hole
Astronomers detected X-ray flashes from the black hole that increased in frequency from one every 18 minutes to one every seven minutes.
Astronomers detect rare X-ray flares from black hole 1ES 1927+654 caused by a nearby white dwarf
The observations revealed features never before seen in real time around a supermassive black hole. Among them was the launch of a plasma jet moving at nearly one-third the speed of light.
