WVTICs -- SPH initial conditions for everyone
Alexander Arth, Julius Donnert, Ulrich Steinwandel +5
We present a novel and fast application to generate glass-like initial conditions for Lagrangian hydrodynamic schemes (e.g. Smoothed Particle Hydrodynamics (SPH)) following arbitra…
Simulations of the merging cluster of galaxies Cygnus A
Timo Halbesma, Julius Donnert, Martijn de Vries +1
The archetype FR-II galaxy Cygnus A lies in a moderately rich cluster about to undergo a major merger. We study the pre-merger Cygnus cluster environment using smoothed particle hy…
WENO-Wombat: Scalable Fifth-Order Constrained-Transport Magnetohydrodynamics for Astrophysical Applications
J. M. F. Donnert, H. Jang, P. Mendygral +3
Due to increase in computing power, high-order Eulerian schemes will likely become instrumental for the simulations of turbulence and magnetic field amplification in astrophysical…
Magnetic Field Amplification in Galaxy Clusters and its Simulation
J. Donnert, F. Vazza, M. Brüggen +1
We review the present theoretical and numerical understanding of magnetic field amplification in cosmic large-scale structure, on length scales of galaxy clusters and beyond. Struc…
Towards Exascale Simulations of the ICM Dynamo with WENO-Wombat
J. Donnert, H. Jang, P. Mendygral +3
In galaxy clusters, modern radio interferometers observe non-thermal radio sources with unprecedented spatial and spectral resolution. For the first time, the new data allows to in…
Deep LOFAR observations of the merging galaxy cluster CIZA J2242.8+5301
D. N. Hoang, T. W. Shimwell, A. Stroe +20
Previous studies have shown that CIZA J2242.8+5301 (the 'Sausage' cluster, ) is a massive merging galaxy cluster that hosts a radio halo and multiple relics. In this paper…
