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

I review the current state of numerical simulations of stellar feedback in the context of star
formation at scales ranging from the formation of individual stars to models of galaxy …

The first stars fundamentally transformed the early universe by emitting the first light and by
producing the first heavy elements. These effects were predetermined by the mass …

A new code for astrophysical magnetohydrodynamics (MHD) is described. The code has
been designed to be easily extensible for use with static and adaptive mesh refinement. It …

We present the detailed global structure of black hole accretion flows and outflows through
newly performed two-dimensional radiation-magnetohydrodynamic simulations. By starting …

The quasi-steady structure of supercritical accretion flows around a black hole is studied
based on two-dimensional radiation-hydrodynamic (2D-RHD) simulations. The supercritical …

Aims. We present a new three-dimensional radiation hydrodynamics code called
HERACLES that uses an original moment method to solve the radiative transfer. Methods …

This paper describes ZEUS-MP, a multiphysics, massively parallel, message-passing
implementation of the ZEUS code. ZEUS-MP differs significantly from the thoroughly …

Outflows driven by large-scale magnetic fields likely play an important role in the evolution
and dispersal of protoplanetary disks and in setting the conditions for planet formation. We …

Black-hole accretion systems are known to possess several distinct modes (or spectral
states), such as low/hard state and high/soft state. Since the dynamics of the corresponding …
