A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of ...

How did supermassive black holes get big so fast? Astrophysicist Souphie Koudmani tells us how she and her colleagues are finding out.

“The cosmic web of dark matter is a solid prediction of our cosmological model of the Universe, and it can be described in detail using numerical simulations,” says co-author says Elia ...

Astronomers used the James Webb Space Telescope to detect ancient lonely quasars with murky origins. They appear to have few cosmic neighbors, raising questions about how they first emerged more than ...

Astronomers studying the aftermath of a supernova explosion have located the original star, a celestial body that should have ...

computer simulations suggest that up to 70% of the mass of the BCG — and others like it in all clusters — comes from material that has become caught up in their cluster's gravitational web and ...

Space experts from the Massachusetts Institute of Technology (MIT) have made a big discovery from close to the beginning of time concerning supermassive black holes and dark matter. Using the $10 ...

A third, tenuously held companion to the known binary V404 Cygni may signal that at least some black holes form "gently." ...
