Cornell Physicists Contribute to Discovery of Colliding Neutron Stars
On Oct. 16, astronomers announced that they had viewed a cosmic event, the collision of two neutron stars, through both light and gravitational waves. Over a thousand scientists working with LIGO, the U.S.-based Laser Interferometer Gravitational Wave Observatory, and Virgo, an Italy based observatory, contributed to the ground-breaking discovery. Three of these researchers were Prof. Saul Teukolsky, physics and astrophysics, research associate Prayush Kumar and senior research associate Larry Kidder. Gravitational waves were first detected in late 2015.
