Pulsar bow-shock nebulae [PDF]

, 2002
We present hydrodynamical simulations, using a 2-D two component model (ambient medium and pulsar wind have different specific heat ratios), of bow shocks in a representative regime for pulsar wind driven bow-shock nebulae.

NuSTAR and XMM-Newton Observations of PSR J1930+1852 and Its Pulsar Wind Nebula

The Astrophysical Journal
Synchrotron X-ray emission from a pulsar wind nebula (PWN) is a sensitive probe of its magnetic field and high-energy particle population. Here we analyze contemporaneous NuSTAR and XMM - Newton observations of the PWN G54.1+0.3, powered by pulsar PSR ...

The Theory Of Pulsar Wind Nebulae: Recent Progress [PDF]

Proceedings of High Energy Phenomena in Relativistic Outflows VII — PoS(HEPRO VII), 2020
Pulsar Wind Nebulae are highly intriguing astrophysical objects in many respects. They are the brightest and closest class of relativistic sources, and hence the ultimate laboratory for the physics of relativistic plasmas: several processes observed (or inferred to occur) in other classes of relativistic sources can here be studied with unique detail ...

Physics and Observations of Pulsar Wind Nebulae [PDF]

, 2018
Pulsar wind nebulae (PWNe) are the largest class of Galactic high energy TeV sources. A pulsar is a rapidly rotating, highly magnetized neutron star produced in a supernova explosion at the end stage of massive stellar evolution.

VHE observations of pulsar wind nebulae with H.E.S.S. [PDF]

, 2005
The H.E.S.S. detector is an array of atmospheric-Cherenkov telescopes dedicated to the observation of very high energy (VHE)γ-rays. Situated in Namibia, the full four-telescope array is operational since December 2003.

Turbulent Transport Characteristics of the Particles within Pulsar Wind Nebulae 3C58 and G54.1+0.3

The Astrophysical Journal
Turbulent transport characteristics of the particles within two Crab-like pulsar wind nebulae (PWNe), 3C58 and G54.1+0.3, are investigated in the framework of a time-dependent turbulent diffusion model.

Radio Observation of the Pulsar Wind Nebula in Supernova Remnant G11.2−0.3

The Astrophysical Journal
Pulsar wind nebulae (PWNe) are important sources for understanding galactic high-energy processes, but it is controversial until now how high-energy particles in PWNe are accelerated and transported. Lacking radio counterparts of X-ray PWNe (the proposed

High-energy Pulsar Wind Nebulae and SuperNova Remnants [PDF]

, 2011
After the second year of Fermi orbiting, the number of galactic sources associated with Pulsar Wind Nebulae (PWNe) and SuperNova Remnants (SNRs) has largely increased.

High-resolution Radio Study of Pulsar Wind Nebula MSH 15–52 and Supernova Remnant RCW 89

The Astrophysical Journal
We present high-resolution radio observations of the pulsar wind nebula (PWN) MSH 15–5 2 , which is renowned for its distinctive handlike shape, and its associated supernova remnant RCW 89. Using the Australia Telescope Compact Array, we obtained 3 and 6
