SUNSET: 
The Challenge of Weird Black Hole Mergers
When spacetime shivers last only a fraction of a second — as in the case of the massive-black-hole merger GW190521 — astronomers struggle to uncover their origins.

What LIGO Teaches Us About Black Holes
The rising count of gravitational-wave events is giving us a new look at a once-invisible population of black holes.
Gravitational-Wave Observatories Bag Four Black-Hole Collisions
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.
Seen at Last: A Superfast Jet Streams Away from Neutron-star Smashup
A new finding suggests that LIGO’s neutron-star merger was a typical gamma-ray burst after all.
Gravitational Waves Shed Light on Neutron Star Interiors
The gravitational-wave detection last year of a neutron star merger has revealed details on neutron star structure, ruling out exotic quark matter in the objects’ cores.
LIGO Sees Smallest Black Hole Binary Yet
LIGO has detected another black hole merger, raising the tally to five.
Astronomers Catch Gravitational Waves from Colliding Neutron Stars
Spacetime ripples from the neutron star smash-up usher in the age of multi-messenger astronomy.
2017 Nobel Goes to Gravitational Waves
Three American physicists have received the Nobel Prize in physics for their contributions to the discovery of gravitational waves.
Fourth Gravitational Wave Event Detected
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.
LIGO Detects Third Black Hole Merger
Scientists with the gravitational-wave observatory announce another discovery, this time of a black hole merger twice as far away as previous detections.
LIGO Detects Second Black Hole Collision
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…
About The LIGO Gravitational-Wave Rumor. . .
Gossip is racing around the physics and astronomy community: has LIGO finally heard its first black-hole merger? Here’s the reality.
