Magnetic dissipation in the Crab Nebula [PDF]

, 2012
Magnetic dissipation is frequently invoked as a way of powering the observed emission of relativistic flows in Gamma Ray Bursts and Active Galactic Nuclei. Pulsar Wind Nebulae provide closer to home cosmic laboratories which can be used to test the hypothesis.

SIMULTANEOUS OBSERVATIONS OF GIANT PULSES FROM THE CRAB PULSAR, WITH THE MURCHISON WIDEFIELD ARRAY AND PARKES RADIO TELESCOPE: IMPLICATIONS FOR THE GIANT PULSE EMISSION MECHANISM [PDF]

, 2015
We report on observations of giant pulses from the Crab pulsar performed simultaneously with the Parkes radio telescope and the incoherent combination of the Murchison Widefield Array (MWA) antenna tiles.

Future X-ray Polarimetry of Relativistic Accelerators: Pulsar Wind Nebulae and Supernova Remnants

Galaxies, 2018
Supernova remnants (SNRs) and pulsar wind nebulae (PWNs) are among the most significant sources of non-thermal X-rays in the sky, and the best means by which relativistic plasma dynamics and particle acceleration can be investigated.

Spectra of Crab-like pulsars

The Astrophysical Journal, 1989
Un modele est construit pour le rayonnement energetique resultant de la formation d'une region de depletion des charges (gap) dans la magnetosphere exterieure des pulsars en rotation rapide. Le modele utilise une procedure iterative avec un parametre variant qui represente la fraction lineaire de la magnetosphere occupee par le gap.

Observations of the Crab Pulsar with VERITAS [PDF]

arXiv, 2013
The Fermi space telescope has detected over 100 pulsars. These discoveries have ushered in a new era of pulsar astrophysics at gamma-ray energies. Gamma-ray pulsars, regardless of whether they are young, old, radio-quiet etc, all exhibit a seemingly unifying characteristic: a spectral energy distribution which takes the form of a power law with an ...

The Crab pulsar and its environment [PDF]

arXiv, 2002
We present new data of the Crab pulsar and its environment. Images taken in the infrared with ISAAC allow us to measure the pulsar spectrum and to reveal the red knot close to the pulsar. Complementary optical data from VLT and HST are presented.

Detection of the crab pulsar with MAGIC

, 2009
The MAGIC telescope has detected for the first time pulsed gamma-rays from the Crab pulsar in the VHE domain. The observations were performed with a newly developed trigger system that allows us to lower the energy threshold of the telescope from 55 GeV to 25 GeV.

Two-Stream Instability as a Mechanism for Toroidal Magnetic Field Generation in the Magnetosphere of Crab Pulsar [PDF]

arXiv, 2011
New plasma mechanism for the generation of toroidal magnetic field in the magnetosphere of Crab pulsar is presented. It is based on the development of two-stream instability in the relativistic electron-positron plasma of the pulsar magnetosphere. In particular, pulsar magnetosphere relativistic plasma is penetrated by ultrarelativistic electron beam ...
