"Extreme Core-collapse Supernovae in Three Dimensions"

Abstract:

Hyperenergetic type Ic-bl and superluminous core-collapse supernovae belong to the most extreme transient events in the universe and are a key factor in the supernova gamma-ray burst connection. The advent of major time-domain astronomy programs such as the Zwicky Transient Facility will revolutionize the science and our understanding of these events. In this talk I will present results from high-fidelity three-dimensional magnetohydrodynamics simulations of extreme core-collapse supernovae with an emphasis on the engines driving the explosion and their observational signatures. I will conclude by discussing how magnetic fields and turbulence as the key ingredients in these engines also play a critical role in many other astrophysical systems, for example in modeling the gravitational wave and electromagnetic emission from compact object mergers in the era of advanced LIGO.
