Numerical solutions of partial differential equations enable a broad range of scientific
research. The Dedalus project is a flexible, open-source, parallelized computational …

Context. Computational astrophysics nowadays routinely combines grid-adaptive
capabilities with modern shock-capturing, high resolution spatio-temporal integration …

The design and implementation of a new framework for adaptive mesh refinement
calculations are described. It is intended primarily for applications in astrophysical fluid …

A common situation in galactic and intergalactic gas involves cold dense gas in motion
relative to hot diffuse gas. Kelvin–Helmholtz instability creates a turbulent mixing layer and …

We find that clouds of optically thin, pressure-confined gas are prone to fragmentation as
they cool below∼ 106 K. This fragmentation follows the lengthscale∼ cst cool, ultimately …

The cores of main sequence intermediate-and high-mass stars are convective. Mixing at the
radiative–convective boundary, waves excited by the convection, and magnetic fields …

We present Phantom, a fast, parallel, modular, and low-memory smoothed particle
hydrodynamics and magnetohydrodynamics code developed over the last decade for …

We present the black hole accretion code (BHAC), a new multidimensional general-
relativistic magnetohydrodynamics module for the MPI-AMRVAC framework. BHAC has …

This paper describes the design and implementation of our new multigroup,
multidimensional radiation hydrodynamics code F ornax and provides a suite of code tests …

We use idealized 3D hydrodynamic simulations to study the dynamics and thermal structure
of the circumgalactic medium (CGM). Our simulations quantify the role of cooling, stellar …
