Observing the Universe with Gravitational Waves
Document Type
Presentation
Description
Gravitational waves were predicted by Einstein’s Theory of General Relativity as fluctuations in the fabric of space-time caused by accelerated masses. In 2015, the Advanced LIGO gravitational-wave detectors observed the first gravitational waves generated in a merger of two black holes. Since then, nearly 100 similar observations have been made, revealing objects and events that would otherwise remain hidden from traditional telescopes and other detectors. I will discuss how gravitational waves arise in some of the most energetic systems in the universe, such as binary systems involving black holes and/or neutron stars. I will describe the state-of-the-art technology used by modern detectors, such as LIGO, to observe gravitational waves. Finally, I will discuss some of the recent gravitational wave observations and some of our expectations for the upcoming observation runs. - Vuk Mandic is a Distinguished McKnight University Professor at the University of Minnesota, co-recipient of multiple awards and prizes with the LIGO Scientific Collaboration, and Fellow of the American Physical Society.
