In this chapter, we review some features of particle acceleration in astrophysical jets. We
begin by describing four observational results relating to the topic, with particular emphasis …

When astrophysical jets were discovered one hundred years ago, the field of numerical
simulations did not yet exit. Since the arrival of programmable computers though, numerical …

Merging neutron stars offer an excellent laboratory for simultaneously studying strong-field
gravity and matter in extreme environments. We establish the physical association of an …

The binary neutron-star merger GW170817 was accompanied by radiation across the
electromagnetic spectrum and localized to the galaxy NGC 4993 at a distance of about 41 …

We present two new Lagrangian methods for hydrodynamics, in a systematic comparison
with moving-mesh, smoothed particle hydrodynamics (SPH), and stationary (non-moving) …

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

The analysis of complex multiphysics astrophysical simulations presents a unique and
rapidly growing set of challenges: reproducibility, parallelization, and vast increases in data …

Aims. Recent observations by the Atacama Large Millimeter/submillimeter Array (ALMA) of
disks around young stars revealed distinct asymmetries in the dust continuum emission. In …

Hydrodynamic cosmological simulations at present usually employ either the Lagrangian
smoothed particle hydrodynamics (SPH) technique or Eulerian hydrodynamics on a …

We present a description of the adaptive mesh refinement (AMR) implementation of the
PLUTO code for solving the equations of classical and special relativistic …
