Teaming up with LIGO, Europe’s Virgo detector has bagged its first gravitational waves. The three-observatory detection enabled scientists to better pinpoint the merging black holes’ location.
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 detected by physicists working with…
Scientists with the gravitational-wave observatory announce another discovery, this time of a black hole merger twice as far away as previous detections.
LIGO has detected another black hole merger, raising the tally to five.
Astronomers monitoring a tight pair of supermassive black holes have observed their orbital motion.
New calculations reveal what two supermassive black holes about to merge would look like in ultraviolet and X-rays.
