The LIGO-Virgo-KAGRA Collaboration unveiled several studies that shed important new light on the nature of gravitational waves. They include a “census” of gravitational wave events to date and a new catalog of results from the second half of its third observing run.

For the first time, scientists detected gravitational waves caused by mergers between black holes and neutron stars. Researchers from RIT’s Center for Computational Relativity and Gravitation (CCRG) helped identify key characteristics about the merger events.

The National Science Foundation recently awarded researchers at RIT, the University of Illinois at Urbana-Champaign, Louisiana State University, Georgia Tech and West Virginia University grants totaling more than $2.3 million to support further development of the Einstein Toolkit, a community-developed code for simulating the collisions of black holes and neutron stars, as well as supernovas and cosmology.
