Relativistic Simulations of Core-collapse Supernovae

The endings of massive stars balance the effects of magnetized fluid flow, neutrinos, relativity, and nuclear physics on a knife's edge. Depending on the conditions when the stars initially collapse, they may either brilliantly explode or implode to form black holes. Central to the supernova dynamics, neutrino properties, and compact object formation are proper treatments of relativity. In this talk, I review ongoing developments of full numerical relativity simulations of supernovae to capture supernova evolution, black hole formation, and beyond.
