Physics Theory Seminar with Andrew Steiner on Multi-Messenger Astronomy

Multi-messenger astronomy is a boon for the astronomical sciences, but it is also a boon for nuclear physics -- in particular the physics of hot and dense strongly-interacting matter. In this talk, I will begin by describing how the combination of electromagnetic and gravitational wave observations which to constraints on neutron star masses and radii constrain the equation of state of cold dense matter. I will proceed to using neutron star observations to constrain the composition and the extent of superfluidity in dense matter. Future multi-messenger observations of neutron star mergers, via both photons and gravitational waves, will continue to be an important laboratory for nuclear physics. This progress will, however, only be possible through a combined effort between nuclear physicists and astrophysicists -- including those who simulate neutron star mergers.

Post-docs and students' Q&A with the speaker starts at 2:15 pm.
