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 …

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

Fully general relativistic models of astrophysical sources are in high demand, not only since
the discovery of gravitational waves emitted from merging stellar mass black holes (Abbott et …

The topology and dynamics of the three-dimensional magnetic field in the solar atmosphere
govern various solar eruptive phenomena and activities, such as flares, coronal mass …

Einstein's General theory of relativity (GR) successfully describes gravity. Although GR has
been accurately tested in weak gravitational fields, it remains largely untested in the general …

Astrophysicists are increasingly taking into account the effects of orbiting companions on
stellar evolution. New discoveries have underlined the role of binary star interactions in a …

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

We present an asymptotically and unconditionally stable numerical method to account for
the momentum transfer between multiple species. Momentum is conserved to machine …

Computational astrophysics is a new and quickly growing discipline. In this book the authors
outline the fundamentals for computational astrophysics, focusing on the use of the …

Context. Worldwide very long baseline radio interferometry (VLBI) arrays are expected to
obtain horizon-scale images of supermassive black hole candidates and of relativistic jets in …
