LIGO, gravitational waves and the new astronomy (Free Astronomy Public Lectures)

On September 14, 2015, gravitational waves from the merger of two black holes rippled through the Laser Interferometer Gravitational-wave Observatory (LIGO). The measurement of these ripples would ultimately lead to the first direct detection of gravitational waves, the first observation of a binary black hole, and the birth of an entirely new field of astronomy. In this talk, Dr Eric Thrane from Monash University, will trace the history of gravitational waves from Einstein to the LIGO detection. Dr Thrane will describe how LIGO works and how we are using it to learn about black holes and other interesting objects. He'll also discuss the future of gravitational-wave astronomy in Australia and around the world. Presented on 16 December 2016.
