Astrophysical Lessons from Gravitational-wave Detections
ZoomSharan Banagiri, Northwestern University
The last decade has seen the rapid rise of gravitational-wave astronomy, made possible by the astonishingly sensitive LIGO and Virgo gravitational-wave detectors. The number of gravitational wave detections has skyrocketed and each year seems to promise something new. Sharan will give a brief introduction to gravitational-wave astronomy and then will describe the latest discoveries and what they tell us about the universe; including the first intermediate-mass black holes ever detected and the first potential neutron star black-hole binaries. Sharan will then give an outlook for the future and what new things we can expect over the next decade.
