Title: Eruptions, Disruptions and Explosions: Massive Stars at the End of their Lives
Speaker: Raffaella Margutti, Harvard University
Host: Vicky Kalogera
Abstract: Stellar explosions are at the intersection of several critical areas of modern Astronomy: as probes of the early Universe, as electromagnetic signposts of gravitational wave and neutrino emitters, as laboratories for extreme physics. In this talk I present the recent results from my multi-wavelength effort designed to (i) constrain the stellar progenitors and their evolution in the years before the terminal explosion; (ii) shed light on the physical mechanism that enables only a small fraction of stellar explosions to harbor and launch a relativistic jet. By taking advantage from DISCOVERY -provided by observations of the transient sky- and DEEP-INSIGTH -that only a truly multi-wavelength perspective can offer-, I show how this study paves the way to the upcoming era of multi-messenger astronomy.
