597445 external_news 1508171164 1508178003 The Aug.17, 2017, detection of gravitational waves and light from the merger of two neutron stars set off a race against time around the globe. Astronomers scrambled to confirm data that could be seen by telescopes and measured by gamma-ray, x-ray and radio wave detection equipment before they all faded away. Laura Cadonati, associate professor in the School of Physics and LIGO Scientific Collaboration deputy spokesperson, explains how these gravitational waves lasted longer than those from four previous incidents caused by black hole collisions. Cadonati is a member of the Center for Relativistic Astrophysics.
