Unleashing CHIMERA: Multidimensional Supernova Simulations

Core-collapse supernovas, stars whose iron cores exceed the Chandrasekhar mass and implode under their own weight, litter the universe with most of the elements in the periodic table—all of the gold in California is the result of their demise.

They are also prodigious sources of neutrinos, gravitational waves, and photons across the electromagnetic spectrum and lead to the formation of neutron stars and black holes. Despite their importance in the universe, however, the mechanism responsible for the explosion of these supernovas is not fully understood.
