Scientists at RIT’s Center for Computational Relativity and Gravitation have used a novel technique to compare gravitational wave observations to their archive of nearly 1,000 simulations, obtaining more accurate information about binary black hole mergers identified in the first two observing runs of current gravitational wave detectors. The new study is published in Physical Review D. Authors include James Healy, research associate, School of Mathematical Sciences; Carlos Lousto, professor, School of Mathematical Sciences; Jacob Lange ’18 MS (astrophysical sciences and technology), ’20 Ph.D. (astrophysical sciences and technology); and Richard O'Shaughnessy, associate professor, School of Mathematical Sciences.
