Astronomers find hundreds of 'hidden' black holes — and there may be billions or even trillions moreBlack holes that have been obscured by clouds of dust still emit infrared light, enabling astronomers to spot them for the ...
In our study published on October 21, 2024, in the journal Physical Review Letters, we predict the existence of a new type of black hole that would be surrounded by rings similar in shape to those of ...

Dark matter might make space-time ring like a bell around black holes — and we might be able to 'hear' itThe researchers found that the emitted dark matter would ring space-time like a bell around the black hole. It would not be as strong of a signal as the ones that come from black hole mergers ...
A constellation of small satellites could help researchers view processes in close vicinity of supermassive black holes like ...
The black hole, with an official name of 1ES 1927+654, is located in the distant constellation Draco. Astronomers have been monitoring the black hole for years, primarily since 2018 when the mass ...
"For such a faint and unknown target, we were not sure if we would get any data at all — but the strategy worked." ...
But there are key distinctions. "Because Sagittarius A* is a much smaller black hole - it's around a thousand times smaller - its ring structure changes on timescales that are a thousand times ...
It was such a violent event that even the overall ring structure of the black hole itself appeared to change in relation to the flare, suggesting an intriguing relationship between the two.
