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.
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.
A new finding suggests that LIGO’s neutron-star merger was a typical gamma-ray burst after all.
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.
Spacetime ripples from the neutron star smash-up usher in the age of multi-messenger astronomy.
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…
