At 7:00 PM, 2020 June 12, online on Zoom, the Sunshine Coast Centre of the RASC presents Dr. Jessica McIver, whose topic is: Spacetime, black holes, and cosmic collisions! Sensing gravitational waves with Advanced LIGO.
The Advanced LIGO detectors measure gravitational waves (GWs), tiny ripples in the fabric of spacetime emitted by accelerating mass. Kilometer-scale interferometers like LIGO can decode the signature of highly energetic systems that are otherwise hidden from us in the dark of deep space. In just four years, GWs have already revealed 11 black hole collisions and two neutron star mergers, one with a spectacular light counterpart signal.
Dr. McIver will summarize what General Relativity, spacetime, and gravitational waves can tell us about the Universe. She will discuss the technology of laser interferometers like Advanced LIGO and how we’re able to sense incredibly small spacetime fluctuations induced by GWs. She will also give an overview of the results from the past LIGO-Virgo observing run, and prospects for the future of gravitational wave astronomy.
Admission is free.
