Gravitational-Wave Catalog

Black Holes

Black holes of ‘all shapes and sizes’ in new gravitational-wave catalog

On November 7, 2021, the LIGO-Virgo-KAGRA Collaboration released the largest catalog ever of collisions involving black holes and neutron stars.
Gravitational waves, ripples in spacetime, from these collisions were picked up by a worldwide team of scientists using the international gravitational-wave observatory network.
As detailed in several papers published on the ArXiv, the team has detected a further 35 gravitational wave events since the last catalog release in October 2020, bringing to 90 the total number of observed events since gravitational-wave observations began.
The Gravitation & Astrophysics group at UZH has been part of the LIGO Scientific Collaboration since 2017, with postdocs M. Haney, S. Tiwari, E. Hamilton and Ph.D. students M. Ebersold, D. Lopez contributing to the results of gravitational-wave discoveries.
