No mountains detected yet on millisecond pulsars
A recently released pre-print by the LIGO Scientific Collaboration and Virgo Collaboration reports the most sensitive test yet of the ellipticity of millisecond pulsars. Researchers in the gravitational-wave astrophysics group at UBC played a key role in new results for five known pulsars using data from the most recent LIGO and Virgo observing run. “This […] Read More
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 […] Read More
UBC gravitational wave astrophysics group participates in the #Strike4BlackLives
The UBC gravitational wave astrophysics group joins the American Physical Society, the AAAS, the LIGO Scientific Collaboration, the journals Science and Nature, and the arXiv in participating in the strike organized on June 10, 2020. Patrick Brady, the LIGO Scientific Collaboration spokesperson, said of the strike: It’s a call to set aside our usual scholarly […] Read More
UBC GW astrophysics group research continues remotely
The UBC gravitational-wave astrophysics group has been researching remotely since March 16, 2020. Zoom and slack have been invaluable tools to keep us connected with each other and with our colleagues in the LIGO Scientific Collaboration, as well as Virgo and KAGRA. Robert Beda, a UBC student studying Mathematical Physics, has remotely joined the group […] Read More
LIGO-Virgo ends third observing run early
In response to the COVID-19 pandemic, LIGO and Virgo decided to suspend their third observing run (O3) roughly a month ahead of schedule. The observing run will end on March 27th instead of the original planned end date, April 30, 2020. From a statement released by the LIGO Laboratory on ligo.caltech.edu: In spite of the early […] Read More
Detector characterization at LIGO Livingston
Group members 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. Jess led the meeting, which focused on plans for LIGO detector noise studies and supporting validation of event candidates in the remainder of the current LIGO-Virgo […] Read More
