Tiny diamond crystals could be used as an incredibly sensitive and small gravitational detector capable of measuring gravitational waves, suggests new UCL-led research. Predicted by…
A cutting-edge vibration sensor may improve the next generation of gravitational-wave detectors to find the tiniest cosmic waves from the background hum of Earth’s motion….
A black hole around 23 times the size of the Sun has swallowed a mysterious, much smaller astrophysical object, according to new research announced today by the LIGO and Virgo gravitational wave observatories,…
For decades astronomers have been puzzled by a gap that lies between neutron stars and black holes, but a major new discovery has found a…
Gravitational wave detectors are extremely complex instruments of precision measurement. They use interference as the physical mechanism to measure passing gravitational waves (GWs)—ripples in space-time—from…
LIGO and Virgo Find Another Surprising Binary System The harvest of exceptional gravitational-wave events from LIGO’s and Virgo’s third observing run (O3) grows. A new…
Most massive stars are born in binaries (and sometimes triples, quadruples, and so on—being single isn’t common for such rock stars!) As stars age, they…
Earlier this year, an international team of scientists announced the second detection of a gravitational-wave signal from the collision of two neutron stars. The event,…
In a study recently published in the Monthly Notices of the Royal Astronomical Society, researchers Dr. Jade Powell and Dr. Bernhard Mueller from the ARC…
Gravitational-wave researchers at the University of Birmingham have developed a new model that promises to yield fresh insights into the structure and composition of neutron…
Scientists from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) reveal an alternative explanation of the recently announce black hole merger. The paper…
Improved deformable precision mirrors could improve sensitivity of gravitational wave detectors to help scientists detect new sources of gravitational waves from deep in space. Researchers…
Gravitational-wave astronomy provides a unique new way to study the expansion history of the Universe. On August 17, 2017, the LIGO and Virgo collaborations first…
Computer models of merging neutron stars predicts new signature in the gravitational waves to tell when this happens. Neutron stars are among the densest objects…
On the 17th of August 2017, the world of astronomy bore witness to an unprecedented event: the LIGO/Virgo collaboration recorded the vibrations of a merging…
Today, team COMPAS (Compact Object Mergers: Population Astrophysics and Statistics) has announced the first public beta release of their rapid binary population synthesis code (available…
A new collaborative study with the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) reveals a possible collision of two neutron stars earlier in…
International team uses a novel approach combining gravitational-wave observations, multi-messenger astronomy, and nuclear physics to obtain the best measurement of neutron star size to date….
