Black Hole, X-Ray and White Dwarf

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
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 observe X-ray flashes from a nearby supermassive black hole that accelerate mysteriously
One supermassive black hole has kept astronomers glued to their scopes for the last several years. First came a surprise disappearance, and now, a precarious spinning act.
Mysterious flashes from a distant black hole puzzles astronomers
Astronomers have observed strange behaviors in a distant black hole. Plasma jets are moving fast, and X-ray flashes are increasing in frequency. They suspect a white dwarf is orbiting close to the black hole's event horizon.
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?
Astronomers Discover Supermassive Black Hole Firing a Powerful Energy Beam at Earth
Astronomers have identified a rare cosmic phenomenon: a supermassive black hole, known as J0410−0139, located 12.9 billion light-years from Earth. This black hole, with a mass equivalent to 700 million suns,
Mysterious x-ray flashes are accelerating in a black hole

First Infrared Flare-Up Detected From The Milky Way’s Supermassive Black Hole
Sagittarius A* is the supermassive black hole at the center of the Milky Way. As supermassive black holes go, it is fairly quiet. It’s not creating any galaxy-wide tantrums that should worry us. It does flare up though,
Astronomers Say the ‘Little Red Dots’ Discovered by the JWST Could Be Glowing Due to Supermassive Black Holes
LRDs, or Little Red Dots, were discovered in the first months after the James Webb Space telescope was turned on. However, since then they have perplexed scientists about what they are and what is causing the light.
