Despite the planet’s seeming standstill, graduate students continue to use LIGO to identify astrophysical events. When LIGO, the Laser Interferometer Gravitational-Wave Observatory, and its European…
Study shows LIGO’s 40-kilogram (88 pounds) mirrors can move in response to tiny quantum effects, revealing the “spooky popcorn of the universe.” The universe, as…
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…
When the most massive stars die, they collapse under their own gravity and leave behind black holes; when stars that are a bit less massive…
Object lies between heaviest known neutron star and lightest known black hole. An international research collaboration, including Northwestern University astronomers, has detected a mystery object…
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…
Every year, 2 million black hole mergers are missed — Australian scientists work out how to detect them, revealing a lost 8 billion light-years of…
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…
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…
Scientists from the ARC Centre of Excellence in Gravitational Wave Discovery (OzGrav) reveal the eccentricity of binary black holes: the shape of the orbit formed…
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…
Since the breakthrough in gravitational wave astronomy back in 2015, scientists have been able to detect more than a dozen pairs of closely located black…
On April 25, 2019, the LIGO Livingston Observatory picked up what appeared to be gravitational ripples from a collision of two neutron stars. LIGO Livingston…
New instrument extends LIGO’s reach: Technology “squeezes” out quantum noise so more gravitational wave signals can be detected. Just a year ago, the National Science…
Shrouded in mystery since their discovery, the phenomenon of black holes continues to be one of the most mind-boggling enigmas in our universe. In recent…
