The Crab nebula and its pulsar (referred to together as 'the Crab') have historically played a
central role in astrophysics. True to this legacy, several unique discoveries have been made …

Neutron stars are fascinating astrophysical objects immersed in strong gravitational and
electromagnetic fields, at the edge of our current theories. These stars manifest themselves …

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 …

Fast reconnection operating in magnetically dominated plasmas is often invoked in models
for magnetar giant flares, for magnetic dissipation in pulsar winds, or to explain the gamma …

Magnetic reconnection is a leading mechanism for magnetic energy conversion and high-
energy non-thermal particle production in a variety of high-energy astrophysical objects …

The population of gamma-ray pulsars, including Crab observed in the TeV range, and Vela
detected above 50 GeV, challenges existing models of pulsed high-energy emission. Such …

We investigated the influence of velocity shear and a radial density profile on the spatial
development of the current-driven (CD) kink instability along helically magnetized relativistic …

Black hole–accretion disc systems are the central engines of relativistic jets from stellar to
galactic scales. We numerically quantify the unsteady outgoing Poynting flux through the …

Many powerful and variable gamma-ray sources, including pulsar wind nebulae, active
galactic nuclei and gamma-ray bursts, seem capable of accelerating particles to gamma-ray …

The new generation of powerful instruments is reaching sensitivities and temporal
resolutions that will allow multi-messenger astronomy of explosive transient phenomena …
