Astronomers think they’ve detected a flash created by the merger of two black holes.
Astronomers have caught a black hole colliding with a mysterious companion that might be either one of the most massive neutron stars or the smallest black hole ever detected.
Calculations suggest how black holes have amassed mass and predict what the black holes’ spins should be if this picture is correct.
A re-analysis of data from LIGO and Virgo brings the number of gravitational-wave detections to 11, including the most distant and most powerful black-hole merger yet discovered.
Astronomers have discovered a supermassive black hole not sitting in its customary seat at the center of its galaxy. Gravitational waves from a recent merger may have ejected the black hole.
The gravitational wave observatory has detected a second event, heralding a new era in astrophysics. The day after Christmas last year, the cosmos quietly gifted scientists with gravitational waves — ripples in the fabric of spacetime – produced in a collision between two stellar-mass black holes. It’s the second event…
