Scientists used changes in the supermassive black hole M87*'s accretion disk to infer its orientation, size and turbulence ...

The 2018 observations confirmed the luminous ring seen in 2017, with a diameter of about 43 microarcseconds, matching theoretical predictions for the shadow of a 6.5 billion solar-mass black hole. The ...

The new observations, taken with the Event Horizon Telescope (EHT), provide the most detailed, real-time look yet ... computer models of the black hole's accretion disk. They noticed that the ...

Twin jets erupt from a supermassive black hole in Draco, offering new insights into black hole activity and evolution.

Observations from 2017 and 2018 by the Event Horizon Telescope have enhanced understanding of the supermassive black hole M87*, focusing on its turbulent accretion flow.

The 2018 observations confirmed the luminous ring seen in 2017, with a diameter of about 43 microarcseconds, matching theoretical predictions for the shadow of a 6.5 billion solar-mass black hole. The ...

Strange x-ray pulses hint at a surprisingly long-lived white dwarf orbiting precariously close to a supermassive black hole ...

The interferometer team, led by Steve Ertel, associate astronomer of Steward Observatory, observed several phenomena ...

Using observations from 2017 and 2018, the Event Horizon Telescope (EHT) Collaboration has advanced our understanding of the supermassive black hole at the centre of Messier 87 (M87*). This study ...

Studying it may help scientists figure out how particles behave near black holes. Matter falling toward a black hole forms an accretion disk — a hot, swirling ring of particles that appears like a ...

A large international team of scientists observed a rare event in real time: a dramatic increase in radio emission and the ...
