Abstract The Particle-In-Cell (PIC) method has been developed by Oscar Buneman, Charles
Birdsall, Roger W. Hockney, and John Dawson in the 1950s and, with the advances of …

The combined study of the flaring of active galactic nuclei (AGNs) at radio wavelengths and
parsec-scale jet kinematics with Very Long Baseline Interferometry has led to the view that …

Neutron star mergers are unique laboratories of accretion, ejection, and r-process
nucleosynthesis. We used 3D general relativistic magnetohydrodynamic simulations to …

The present review concerns the relevance of collisionless reconnection in the astrophysical
context. Emphasis is put on recent developments in theory obtained from collisionless …

In the new era of gravitational wave (GW) and multi-messenger astrophysics, the detection
of a GW signal from the coalescence of a black hole–neutron star (BHNS) binary remains a …

We cross-correlate the largest available mid-infrared (Wide-field Infrared Survey Explorer–
WISE), X-ray (3XMM) and radio (Faint Images of the Radio Sky at Twenty centimetres+ …

Detections of gravitational waves (GWs) may soon uncover the signal from the coalescence
of a black hole–neutron star (BHNS) binary, which is expected to be accompanied by an …

We investigate the launching mechanism of relativistic jets from black hole sources, in
particular the strong winds from the surrounding accretion disk. Numerical investigations of …

Semi-analytical models of disc outflows have successfully described magnetically driven,
self-confined super-Alfvénic jets from near-Keplerian accretion discs. These jet-emitting …

We study the evolution of kink instability in a force-free, nonrotating plasma column of high
magnetization. The main dissipation mechanism is identified as reconnection of magnetic …
