Most known black holes are either extremely massive, like the supermassive black holes that lie at the cores of large galaxies, or relatively lightweight, with a mass of under 100 times that of the Sun. Intermediate-mass black holes (IMBHs…
The discovery is the best candidate for a class of black holes astronomers have long believed to exist but have never found - intermediate-mass black holes formed in early stages of galaxy evolution.
Researchers from the Max Planck Institute for Astronomy and the University of Utah have discovered the closest example of a massive black hole ever found.
Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, it is the best candidate for a class of black holes astronomers have…
Scientists from Washington University in St. Louis have launched a balloon-borne telescope to unlock the secrets of astrophysical black holes and neutron stars, some of the most extreme objects in the universe.
Webb’s image of RX J1131-1231 uses gravitational lensing to explore the quasar’s black hole and dark matter, revealing details about its growth and the universe’s...
New theoretical research finds that it's impossible to form a black hole with the energy of light particles alone, poking a hole in Einstein's theory of general relativity.
