Astronomers at the Indian Institute of Astrophysics (IIA), an autonomous institute of the Department of Science and Technology, have recently detected iron Lines in X-rays from a well-known binary ...

Iron Lines in X-ray have been detected from a well-known binary black hole system in the radio galaxy 4C+37.11 750 million light years away from the Earth, making way for study of the properties of ...

In a groundbreaking discovery, astronomers have detected iron K spectral lines in X-ray emissions from the binary black hole system in the radio galaxy 4C+37.11, located 750 million light-years from ...

Black hole ASASSN-22ci consumed a star from a binary system A rare double-flash TDE was observed, with two flares 720 days apart A third flare is predicted in 2026, offering insights into TDE ...

In a galaxy 408 million light-years away, the black hole ASASSN-22ci consumed a star from a binary system, producing a rare double-flash tidal disruption event (TDE). First observed in February ...

In an article published in Physical Review Letters on Thursday, scientists carried out an innovative study testing the ...

New evidence that outbursts from black holes can help cool down gas.

Once black holes are close enough together to form a binary as they whirl around one another, this constant acceleration (acceleration is a change in speed and direction, so circular motion ...

This double-flash Tidal Disruption Event (TDE) could result from the black hole catching binary stars ... Asteroid Terrestrial Impact Last Alert System (ATLAS), ASASSN-22ci surprised them by ...

Over time, this process can bring the black holes closer together, ultimately leading to their merger. Many stars in the universe don’t exist in isolation. Unlike our Sun, many have a stellar ...

If a star orbits a black hole, it will appear from a distance to be orbiting empty space. Gaia projects the star’s orbit on a ...
