SUNSET: 
The Black Hole Files with Camille Carlisle
Third Gravitational-Wave Catalog Released
The latest results from LIGO, Virgo, and KAGRA bring several key revelations, including that black holes tend to come with certain masses.
Jumping the Gap to Probe Large Black Holes
Gravitational-wave detectors should be able to locate a population of huge black holes soon. A new study predicts when we'll find them, and what they'll teach us.
Redefining a Heavy Collision
Could the biggest — literally — gravitational-wave discovery yet be something other than what it initially seemed?
Pulsars Show Hint of Gravitational-wave Background
Duos of supermassive black holes tangoing throughout the universe make their own music, and astronomers may have picked up a hint of the tune.
How to Warn of Imminent Neutron Star Collisions
What if gravitational-wave observatories could send out alerts right after — or even before — receiving signals of neutron star collisions?
Big Black Holes Dominate New Gravitational-Wave Catalog
Gravitational-wave scientists have unveiled their latest catalog of events, revealing a surprising number of massive black holes.
Record-breaking Signal Reveals New Population of Black Holes
Gravitational-wave observatories have detected the most massive black hole merger yet, and it's challenging our ideas of black hole formation.

Gravitational Wave Detectors Find Mystery “Mass Gap” Object
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.
What Kinds of Black Hole Partners Merge?
New research on black hole mergers reveals that the black hole pairs tend to have similar masses — suggesting that they start out as massive stellar pairs.
Mismatched Black Holes Merge
For the first time, the LIGO and Virgo gravitational-wave detectors have "heard" gravitational waves from an unequal pair of black holes.
Gravitational Waves Put Ruler to Neutron Stars
Scientists have combined observations of gravitational waves from a neutron star collision with nuclear theory to shed light on the size and nature of neutron stars.
Gravitational Waves from Second Neutron-star Collision Observed
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.
More Black Hole Mergers Found in LIGO Data
Analysis by an independent team has ferreted out seven candidates for gravitational-wave events from merging black holes.
Listen Up: Get Gravitational-wave Alerts
The Laser Interferometer Gravitational-wave Observatory (LIGO) will soon begin a new round of observations. Now you can find out about the discoveries as they happen.

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.
Astronomers Catch Gravitational Waves from Colliding Neutron Stars
Spacetime ripples from the neutron star smash-up usher in the age of multi-messenger astronomy.
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.
