Universe, 2023 Based on the expected population of core collapse supernova remnants and the huge number of detected pulsars in the Galaxy, still representing only a fraction of the real population, pulsar wind nebulae are likely to constitute one of the largest classes

Pulsar Wind Nebulae and Unidentified Galactic Very High Energy Sources
J, 2022 The riddle of the origin of Cosmic Rays (CR) has been an open question for over a century. Gamma ray observations above 100 MeV reveal the sites of cosmic ray acceleration to energies where they are unaffected by solar modulation; recent evidence ...

GeV Gamma-Ray Emission from Pulsar Wind Nebula HESS J1356-645 with Fermi-Large Area Telescope
The Astrophysical Journal, 2023 HESS J1356-645 is considered to be a pulsar wind nebula (PWN) associated with the pulsar PSR J1357-6429. We reanalyze the GeV gamma-ray emission in the direction of HESS J1356-645 with more than 13 yr of Fermi-Large Area Telescope data.

Gamma-ray pulsar halos in the Galaxy
Frontiers in Astronomy and Space Sciences, 2022 Pulsar halos are extended gamma-ray structures generated by electrons and positrons escaping from pulsar wind nebulae (PWNe), considered a new class of gamma-ray sources.

The contribution of Galactic TeV pulsar wind nebulae to Fermi large area telescope diffuse emission
Communications Physics, 2022 Cosmic Rays (CRs) with energy below 1 PeV are believed to originate in the Milky Way, but recent gamma-ray observations by Fermi Large Area Telescope challenge the interpretation of CR diffusion mechanisms across the galaxy.

Turbulent Diffusion of the Particles within Pulsar Wind Nebulae
The Astrophysical Journal, 2023 A turbulent diffusion model is presented to account for the energy and spatial diffusion of the particles within pulsar wind nebulae (PWNe), with the assumption that the energy injected from the pulsar into the nebula is split between the turbulence ...

Mass-loading of bow shock pulsar wind nebulae [PDF]
, 2015 We investigate the dynamics of bow shock nebulae created by pulsars moving supersonically through a partially ionized interstellar medium. A fraction of interstellar neutral hydrogen atoms penetrating into the tail region of a pulsar wind will undergo ...

Radio Study of the Pulsar Wind Nebula Powered by PSR B1706-44
The Astrophysical Journal, 2023 PSR B1706−44 is an energetic gamma-ray pulsar located inside supernova remnant (SNR) G343.1−2.3 and it powers a compact pulsar wind nebula (PWN) that shows torus and jet structure in X-rays.

Probing the Pulsar Wind Nebula of PSR B0355+54 [PDF]
, 2006 We present XMM-Newton and Chandra X-ray observations of the middle-aged radio pulsar PSR B0355+54. Our X-ray observations reveal emission not only from the pulsar itself, but also from a compact diffuse component extending ~50'' in the opposite direction

A Study of Particle Transport in Young Pulsar Wind Nebulae
The Astrophysical Journal, 2023 The broadband emission of numerous pulsar wind nebula (PWNe) in our Galaxy can be well described by synchrotron radiation and inverse Compton scattering from relativistic particles, specifically electrons and positrons.
