"Einstein, Gravitational Waves, Black Holes and Other Matters," is the lecture topic presented by Gabriela González, PhD, Louisiana State University, for the LIGO Scientific Collaboration and the Virgo Collaboration.
Professor González is one of the leading figures in what is now becoming an entirely new kind of astronomy.
Abstract: More than a hundred years ago, Einstein predicted that there were ripples in the fabric of space-time traveling at the speed of light: gravitational waves. On September 14, 2015, LIGO detectors in the US — Livingston, Louisiana, and Hanford, Washington — registered for the first time ever a loud gravitational wave signal traveling through Earth, created more than a billion years ago by the merger of two black holes.
Several other gravitational waves from black holes were detected since then, including one by LIGO and the Virgo detector in Europe, produced by two neutron stars giving birth to a black hole, generating also electromagnetic waves (light!) detected by many telescopes and helping us understand the origin of gold.
Professor González will describe the history and details of the observations, and the gravity-bright future of the field.
