What do optical telescopes and neutron stars have in common? They can both be used to look for supermassive black hole binaries!
How massive can stellar black holes be?
Before Galileo saw it through a telescope, most people believed that the Moon was a perfect sphere. It is fascinating today that @LIGO-Virgo are able to (correctly) identify perfect spheres over a hundred times smaller than the Moon situated over 300 light years away.
Fast radio bursts have unknown origins, but today’s guest post discusses one possibility: interacting BNS systems.
Finding some real estate for the next gravitational wave detector might not be too hard. The problem? Getting it there.
The most recent gravitational wave merger detected by LIGO/VIRGO consists of two objects with very unequal masses. But just what is the smaller object?
