The project addresses pressing questions in the understanding of 3D core-collapse supernovae (CCSNe) and the 3D evolution of hypermassive magnetized neutron star remnants of neutron star mergers. CCSNe are explosions of massive stars. They are responsible for expelling the products of nuclear fusion into the interstellar medium the elements of life, including most of the oxygen we breathe, the carbon in our bones, and part of the iron in our blood, comes from CCSNe. They are the birth sites of neutron stars and black holes. CCSN shocks plowing through the interstellar medium provide “feedback” to galaxy evolution. They trigger or shut off star formation and expel hot gas into the intergalactic medium. Hence, understanding CCSNe is key (i) to understanding the chemical evolution of the universe, (ii) to understanding the formation of compact objects, and (iii) to understanding the cosmological evolution of galaxies and star formation.
