When Two Massive Black Holes Merged And Went Flying Across Cosmos
The researchers propose that this ejection resulted from the collision of two galaxies, causing their central black holes to merge into a larger one.

Gravitational Waves Reveal Black Hole Ancestry Through Spin Analysis
A study published in Physical Review Letters explores how gravitational waves reveal the ancestry of black holes. By examining 69 black hole mergers, researchers found that spin shifts indicate repeated collisions in dense star clusters. This insight supports models suggesting black holes grow through sequential mergers. Observatories like LIGO and...

Scientists Develop New Approach to Capture Gravitational Wave Memory from Supernovae
A study published in Physical Review Letters highlights new methods to detect the gravitational wave memory effect, a unique phenomenon predicted by Einstein's general relativity. Core-collapse supernovae (massive stellar explosions) generate these low-frequency gravitational waves, offering a rare glimpse into stellar interiors. Despite their weak...

Black Hole Mergers Explained: What Happens When Two Black Holes Collide in Space?
Black hole mergers are among the most energetic events in space. Two black holes gradually lose energy through gravitational interactions, drawing them closer until their event horizons stretch and merge. Gravitational waves released during the process are some of the most powerful forces in the universe, with part of the black holes' mass converti...

Indian Researchers Spot Rare Triple Black Hole System In Nearby Universe
In a rare occurrence, a merger of three supermassive black holes from as many galaxies in our nearby universe was spotted by a team of Indian researchers, said the Ministry of Science and Technology.

Astrophysicists Detect Black Hole-Neutron Star Mergers For The First Time
Astrophysicists say that the newly observed phenomena will allow them to better understand the formation of binary star systems and how often they merge, something that has never been measured before.

Scientists Spot Light Flare From a Black Hole Collision for the First Time Ever
A team of international astronomers believe that they might have detected light from a black hole merger, for the first time ever. This unprecedented event was noted by scientists at Caltech' Zwicky Transient Facility (ZTF) in California after studying gravitational waves and electromagnetic radiation from the collision of two black holes.

Observatory For Gravitational Waves Back Online, Set To Detect More Waves
The twin detectors of LIGO - which made the first ever direct detection of gravitational waves - have been restarted and scientists expect to detect more black hole mergers from farther out in the universe.

Gravitational Waves Detected for Second Time, Say LIGO Researchers
Researchers announced they had found the waves a second time in December, produced by the collision of two black holes some 1.4 billion years ago.

The World's Most Sophisticated Science Machines: LIGO
The machines that gave scientists their first-ever glimpse at gravitational waves are the most advanced detectors ever built for sensing tiny vibrations in the universe.

Physicists Detect Gravitational Waves From Violent Black-Hole Merger
Scientists announced Thursday that, after decades of effort, they have succeeded in detecting gravitational waves from the violent merging of two black holes in deep space. The detection was hailed as a triumph for a controversial, exquisitely crafted, billion-dollar physics experiment and as confirmation of a key prediction of Albert Einstein's Ge...
