  Core-collapse supernovae are among the most powerful explosions in the
Universe, releasing about $10^{53}~\mbox{erg}$ of energy on timescales of a few
tens of seconds. These explosion events are also responsible for the production
and dissemination of most of the heavy elements, making life as we know it
possible. Yet exactly how they work is still unresolved. One reason for this is
the sheer complexity and cost of a self-consistent, multi-physics, and
multi-dimensional core-collapse supernova simulation, which is impractical, and
often impossible, even on the largest supercomputers we have available today.
To advance our understanding we instead must often use simplified models,
teasing out the most important ingredients for successful explosions, while
helping us to interpret results from higher fidelity multi-physics models. In
this paper we investigate the role of instabilities in the core-collapse
supernova environment. We present here simulation and visualization results
produced by our code GenASiS.
