Gravitational waves announcement ushers in new era of multi-messenger astronomy

For the first time, scientists have directly detected gravitational waves in addition to light, from the spectacular collision of two neutron stars. This marks the first time that a cosmic event has been viewed in both gravitational waves and light. Cornell University physicists and experts, who played a vital role in validating the detection of […]

Cornell astrophysicists play vital role to validate detection of gravitational waves

Cornell physics and astrophysics professor Saul Teukolsky has been using supercomputers to solve Einstein’s equations for black hole mergers for much of his career. Teukolsky and the Cornell-founded Simulation of eXtreme Spacetimes (SXS) collaboration group have been calculating and completing a full catalog of theoretical solutions since 2000, when supercomputers first became capable of the […]
