Duos of supermassive black holes tangoing throughout the universe make their own music, and astronomers may have picked up a hint of the tune.
Gravitational-wave scientists have unveiled their latest catalog of events, revealing a surprising number of massive black holes.
Gravitational-wave observatories have detected the most massive black hole merger yet, and it's challenging our ideas of black hole formation.
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.
Scientists with the Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo collaborations have announced the detection of a second pair of neutron stars that went bump in the night.
Only a month into a new observing run, gravitational-wave observatories have announced five new signals — one of which could turn out to be a black hole swallowing a neutron star.
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 massive star lost most of its mass before exploding and creating a neutron star — and a second nearby neutron star might have been the thief.
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.
LIGO’s neutron-star smashup might not have been a typical short gamma-ray burst. If true, the detection points toward a new class of gamma-ray bursts — but the jury is still out.
Spacetime ripples from the neutron star smash-up usher in the age of multi-messenger astronomy.
