The Vela Pulsar and Its Pulsar Wind Nebula Vela-X Using 13 Yr of Fermi-LAT Observations

The Astrophysical Journal
We present results of more than 13 yr of Fermi–Large Area Telescope (LAT) data analysis for the Vela pulsar from 60 MeV to 100 GeV and its pulsar wind nebula (PWN), Vela X, for E  > 1 GeV in the off-pulse phases.

Positrons from pulsar winds

, 2010
Pulsars, or more generally rotation powered neutron stars, are excellent factories of antimatter in the Galaxy, in the form of pairs of electrons and positrons.

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.

Modeling Pulsar Wind Nebulae

, 2007
In the last few years, new observations by CHANDRA and XMM have shown that Pulsar Wind Nebulae present a complex but similar inner feature, with the presence of axisymmetric rings and jets, which is generally referred as {\it jet-torus structure}. Due to

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-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

The Devil is in the Details: Compact Structures in Pulsar Wind Nebulae

, 2005
The large-scale structure of pulsar wind nebulae (PWNe) tells us a considerable amount about their average magnetic fields, the total particle input from the pulsar winds, and the confining pressure at their outer boundaries.

Three-dimensional Analytical Description of Magnetised Winds from Oblique Pulsars

, 2015
Rotating neutron stars, or pulsars, are plausibly the source of power behind many astrophysical systems, such as gamma-ray bursts, supernovae, pulsar wind nebulae and supernova remnants.

Investigating the Anticorrelation between Photon Index and Flux of the Crab Using RXTE and NuSTAR

The Astrophysical Journal
We present a systematic study of the recently reported anticorrelation between X-ray flux and photon index (Γ) in the Crab Nebula, using archival Rossi X-Ray Timing Explorer (RXTE) Proportional Counter Array (3–50 keV), RXTE High Energy X-ray Timing ...
