The scenario that two fundamentally different types of neutron star-neutron star mergers exist — separated by a direct-to-black-hole mass threshold — is a viable, intriguing possibility ...

“The lack of a supernova accompanying the long GRB 191019A tells us that this burst is not a typical massive star collapse,” said study coauthor Jillian Rastinejad, a doctoral student of ...

April 25, 2019 was an exciting day for different groups of astronomers. The second-ever detection of a neutron star collision was reported, being picked up by one of the two LIGO detectors. Two ...

Described in February 2022, the fast radio burst was found within a cluster of stars, called a globular cluster, on the outskirts of galaxy Messier 81, located 12 million light-years from Earth.

But then a radio burst came in from a little closer to home. Before 2007, the next closest source detected was at a distance of 490 million light years away from Earth. This radio signal was ...

Now, astronomers must consider that not all fast radio bursts come from younger galaxies and stars. The powerful burst was also traced to an unprecedented 130,000 light-years from its associated ...
