(Phys.org)—The research team working with the LIGO project has proposed that the data gleaned from the discovery of gravity waves last year allows for calculating the likely level of cosmic background noise due to gravitational ...
(Phys.org)—A team of researchers working at the Astrophysical Institute of the Canary Islands has found evidence of a previously unknown structure in the accretion disk of a black hole that is part of an X-ray binary system. ...
A team of researchers from the U.S. and China has found the first evidence for a candidate planet in another galaxy. In their paper uploaded to the arXiv preprint server, the team describes their work studying the possible ...
Since the breakthrough in gravitational wave astronomy back in 2015, scientists have been able to detect more than a dozen pairs of closely located black holes—known as binary black holes—by their collisions into each ...

(Phys.org)—PKS 1302-102 is one of the few known quasars with a pair of black holes within its accretion disc. It is also a curious case for astronomers as it will produce a powerful explosion when these two black holes ...
Using data from ESA's Gaia mission, astronomers have discovered not only the closest but also the second closest black hole to Earth. The black holes, Gaia BH1 and Gaia BH2, are respectively located just 1,560 light-years ...
