An international team of astronomers has detected a new kilonova associated with a nearby gamma-ray burst (GRB) known as GRB 211211A. The finding, reported in a paper published April 22 on arXiv.org, could improve our understanding ...
Researchers have provided the first plausible explanation to why one of the most massive black hole pairs observed to date by gravitational waves also seemed to merge on a non-circular orbit. Their suggested solution, now ...

When two neutron stars spiral into one another and merge to form a black hole—an event recorded in 2017 by gravitational wave detectors and telescopes worldwide—does it immediately become a black hole? Or does it take ...
