The discovery of pulsars opened a new research field that allows studying a wide range of
physics under extreme conditions. More than 3,000 pulsars are currently known, including …

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 …

Magnetars younger than one century are expected to be hyperactive: besides winds
powered by rotation, they can generate frequent magnetic flares, which launch powerful …

Nonthermal electron acceleration via magnetic reconnection is thought to play an important
role in powering the variable X-ray emission from radiatively inefficient accretion flows …

Context. Low-luminosity supermassive and stellar-mass black holes (BHs) may be
embedded in a collisionless and highly magnetized plasma. They show nonthermal flares …

Some of the most energetic pulsars exhibit rotation-modulated γ-ray emission in the 0.1–100
GeV band. The luminosity of this emission is typically 0.1%–10% of the pulsar spin-down …

In this Letter we propose that coherent radio emission of the Crab pulsar, other young
energetic pulsars, and millisecond pulsars is produced in the magnetospheric current sheet …

Magnetic reconnection is invoked as an efficient particle accelerator in a variety of
astrophysical sources of non-thermal high-energy radiation. With large-scale two …

Pulsar wind nebulae (PWN) are fascinating systems and archetypal sources for high-energy
astrophysics in general. Due to their vicinity, brightness, to the fact that they shine at multi …

Context. The formation of a large-scale current sheet is a generic feature of pulsar
magnetospheres. If the magnetic axis is misaligned with the star rotation axis, the current …
