Core-collapse supernova simulations with CHIMERA

Unraveling the core-collapse supernovae mechanism is an outstanding computational challenge and the problem remains essentially unsolved despite more than four decades of effort. However, progress in realistic modeling has occurred recently through the availability of petascale platforms and the increasing sophistication of supernova codes. CHIMERA is a code we have developed to simulate core-collapse supernovae in one, two, and three spatial dimensions, incorporating modules for ray-by-ray neutrino transport and nuclear kinetics. In addition to this base functionality, CHIMERA includes several other features designed to provide additional capability. For example, the availability of Lagrangian tracer particles in CHIMERA allows us to produce realistic, post-processed estimates for a variety of multi-messenger observables, including supernova nucleosynthesis and gravitational wave signatures.
