Abstract Rayleigh–Taylor (RT) and Richtmyer–Meshkov (RM) instabilities are well-known
pathways towards turbulent mixing layers, in many cases characterized by significant mass …

In a single process, the merger of binary neutron star systems combines extreme gravity, the
copious emission of gravitational waves, complex microphysics and electromagnetic …

Accurate numerical solutions of the equations of hydrodynamics play an ever more
important role in many fields of astrophysics. In this work, we reinvestigate the accuracy of …

We present a numerical parameter survey of sub-Chandrasekhar mass white dwarf (WD)
explosions. Carbon–oxygen WDs accreting a helium shell have the potential to explode in …

Reacting flow simulations for combustion applications require extensive computing
capabilities. Leveraging the AMReX library, the Pele suite of combustion simulation tools …

Using simulations of non-rotating supernova progenitors, we explore the kicks imparted to
and the spins induced in the compact objects birthed in core collapse. We find that the recoil …

We consider multiphysics applications from algorithmic and architectural perspectives,
where “algorithmic” includes both mathematical analysis and computational complexity, and …

We present a new N-body and gas dynamics code, called Nyx, for large-scale cosmological
simulations. Nyx follows the temporal evolution of a system of discrete dark matter particles …

Block-structured adaptive mesh refinement (AMR) provides the basis for the temporal and
spatial discretization strategy for a number of Exascale Computing Project applications in …

High-dimensional spatio-temporal dynamics can often be encoded in a low-dimensional
subspace. Engineering applications for modeling, characterization, design, and control of …
