For the first time, astronomers have observed dust being sucked directly into a supermassive black hole, evidence of “chaotic accretion” that may have helped supermassive holes rapidly gain mass in the early universe.
Astronomers have detected the most distant known radio galaxy, a surprising discovery given the supermassive black hole powering the galaxy was actively accreting gas and dust when the Universe was in its infancy.
Changes in the light emerging from active galactic nuclei, powered by supermassive black holes, may be explained by clouds of intervening dust that can dim and redden the radiation, eliminating the need for more exotic explanations.
Australian astronomers have found one of the fastest-growing super-massive black holes in the known universe, a monster 20-billion-solar-mass quasi-stellar object consuming the equivalent of the Sun’s mass every two days.
Astronomers studying emissions from a black hole have found a relationship between the strength of X-rays generated as material on the way into the hole is heated and the strength of jets blasting energetic particles back into space.
The centre of our galaxy has been intensely studied for many years, but it still harbors surprises for scientists. A snake-like structure lurking near our galaxy’s supermassive black hole is the latest discovery to tantalise astronomers.
A team of astronomers have discovered the most-distant supermassive black hole ever observed. It resides in a luminous quasar and its light reaches us from when the Universe was only 5 percent of its current age — just 690 million years after the Big Bang.
It seems like even black holes can’t resist the temptation to insert themselves unannounced into photographs. A cosmic photobomb found as a background object in images of the nearby Andromeda galaxy has revealed what could be the most tightly coupled pair of supermassive black holes ever seen.
