Probing neutron star physics with gravitational wave detections The recent detection of the binary neutron star merger event (GW170817) has marked the beginning of multi-messenger astronomy with gravitational waves. In this talk I will briefly review current findings associated with GW170817 and introduce new opportunities from future detections. In the first part, I will explain … Continue reading "CRA Seminar: Prof. Huan Yang (Perimeter Institute)"

Observational tests of general relativity with black hole inspiral, coalescence, and ringdown Prof. Lee Samuel Finn (Penn State University) Website: https://www.phys.psu.edu/people/lsf5 Abstract: As far as it has been tested, general relativity “works”; however, tests of general relativity are spotty in their coverage and - especially in the dynamical regime - leave much to be desired … Continue reading "CRA Seminar: Lee Samuel Finn (Penn State University)"
