This Supermassive Black Hole May Harbor a Bizarre Star That Refuses to Die
Strange x-ray pulses hint at a surprisingly long-lived white dwarf orbiting precariously close to a supermassive black hole
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."
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,
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?
Feeding supermassive black holes are more common than thought across the universe
"If our eyes were able to detect X-rays, the sky would be full of dots. And every single one of those dots would be an accreting supermassive black hole."
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,
New research suggests more supermassive black holes than we ever knew
Most picture the night sky as an endless sea of twinkling stars. But if your eyes could see the universe in X-rays, you’d spot thousands upon thousands of bright points representing giant black holes feeding on gas and dust.
Scientists have just realised the universe has more supermassive black holes than anyone believed
According to scientists, there could be more black holes in the universe than previously thought. Researchers reckon astronomers could be missing between 30 per cent and 50 per cent of the feeding supermassive black holes,
