Title: Explosive Transients in the Multimessenger Era

Speaker: Prof. Eric Burns, Louisiana State University

Abstract: Gamma-ray bursts and supernovae arise from explosions caused by the creation, evolution, and death of compact objects. These events are studied across the electromagnetic spectrum and often through other messengers, particularly gravitational waves and neutrinos. For gamma-ray bursts we will highlight the prototypical examples of those arising from neutron star mergers, magnetar giant flares, and collapsars, including recent extraordinary events. For supernovae we'll discuss SN1987A as the exemplar for core-collapse events and, if time permits, how gamma-ray diagnostics of type Ia supernovae may help resolve tensions in the standard cosmological model.
