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...

Astronomers Discover Unusual X-Ray Oscillations From a Black Hole 100 Million Light-Years Away
A supermassive black hole 100 million light-years away is showing an unprecedented increase in X-ray oscillations, starting from 18-minute intervals and accelerating to 7 minutes in just two years. Astronomers believe a white dwarf, orbiting perilously close to the event horizon, is causing these flashes. The findings offer a glimpse into black hol...

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...

Arecibo Observatory Data Helps SETI Uncover Secrets of Pulsar Signals and Cosmic Distortions
Data from the now-collapsed Arecibo Observatory continues to drive major discoveries in space science. Sofia Sheikh and her team from the SETI Institute utilised archived data to investigate the signals of pulsars—dense neutron stars emitting radiation like cosmic lighthouses. Their study focused on how these signals are distorted by interstellar...

Astronomers Spot Imminent Collision Of Supermassive Black Holes In Nearby Galaxy: Report
Astronomers have detected two closely spaced supermassive black holes in the galaxy MCG-03-34-64, located 800 million light-years away.

Technology Day: PM Modi To Lay Foundation Of Gravity Observatory LIGO-India Tomorrow
Prime Minister Narendra Modi will lay the foundation stone of Laser Interferometer Gravitational Wave Observatory India (LIGO-India) on Thursday, when the country celebrates the 25th anniversary of the Pokhran-II nuclear tests.

India To Build Massive Observatory 'LIGO' To Detect Gravitational Waves
LIGO-India will significantly enhance scientists' ability to pinpoint the sources of gravitational waves -- ripples in the fabric of space and time -- and answer fundamental questions about the universe, experts say.

Dozens of Newly-Detected Gravitational-Wave Events May Help Better Understand Black Holes, Neutron Stars
Astrophysicists have found new 39 gravitational-wave events caused by collision of black holes and neutron stars far in the universe. These, along with previously observed 11 events, will help them understand the population of black holes and neutron stars across the universe.

LIGO Detects Gravitational Waves for Third Time as Two Black Holes Merge
As was the case with the first two detections, the waves were generated when two black holes merged to form a larger black hole.
-
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.
-
Second Set Of Gravitational Waves Merging Black Holes Detected
For the second time, scientists have directly detected gravitational waves created by the collision of two black holes 1.4 billion light years away, which once again confirms Einstein's theory of general relativity.
-
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.

Could Black Holes Be the Dark Matter Everyone Has Been Looking For?
Two different papers have been published recently suggesting that LIGO may have stumbled upon the solution to the enduring mystery of dark matter.
