Scientists detect 39 new gravitational wave events
(via UBC News) The LIGO-Virgo Collaboration, including UBC Department of Physics & Astronomy researchers, has confirmed 39 new gravitational wave event detections, more than quadrupling the total known gravitational wave events from 11 to 50. The results, published in four papers on arXiv, and soon to appear in Physical Review X and other journals, were […]
The most massive black hole merger detected
An international team of researchers, including scientists in the UBC LIGO group, has detected a signal from the most massive black hole merger yet observed. The discovery, outlined in papers published today in Physical Review Letters and The Astrophysical Journal, raises a slew of new questions about the nature of black-hole formation, and upends previously […]
Discovery of the heaviest neutron star, or lightest black hole, ever observed
An international team of astrophysicists, including researchers at UBC, have detected the ‘extremely loud’ merger of a black hole with a mystery compact object—the most asymmetric gravitational-wave source yet observed. GW190814, the merger of a heavy black hole with an unidentified compact object about nine times smaller, was reported today in Astrophysical Journal Letters. When […]
UBC researchers visit LIGO Livingston
UBC researchers Jess McIver, Evan Goetz, and student Katie Rink visited the LIGO-Livingston detector in Livingston, Louisiana for the LIGO Detector Characterization meeting and noise sprint in January 2020.
Glimpsing harmonics in gravitational waves
Astrophysicists, including a team at UBC, have observed gravitational waves from the collision of two black holes with distinctly different masses, dubbed GW190412. This discovery gives us a glimpse of subtle harmonics in gravitational wave signals for the first time. These harmonics not only allow improved tests of Einstein’s theory of general relativity, they also […]
