Modeling Pulsar Wind Nebulae [PDF]

Advances in Space Research, 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

Understanding Pulsar Wind Nebulae with the SKA

The Open Journal of Astrophysics
Produced by the interaction between the "pulsar wind'' powered by the rotational energy of a neutron star and its surroundings, the study of pulsar wind nebulae (PWNe) provides vital insight into the physics of neutron star magnetospheres and ultra ...

Pulsar Wind Nebulae Created by Fast-Moving Pulsars [PDF]

Journal of Plasma Physics, 2017
We review multiwavelength properties of pulsar wind nebulae (PWNe) created by supersonically moving pulsars and the effects of pulsar motion on the PWN morphologies and the ambient medium.

TeV halos and the role of pulsar wind nebulae as sources of cosmic-ray positrons [PDF]

Physical Review D, 2023
The recent detection of the Geminga PWN by HAWC in the multi-TeV band allows us to infer precious information about the transport of pairs in the immediate surroundings of the pulsar and on the spectrum of pairs contributed by a Geminga-like pulsar to ...

The power-law component of the X-ray emissions from pulsar-wind nebulae and their pulsars [PDF]

Monthly notices of the Royal Astronomical Society, 2021
To look for possible phenomenological connections between pulsar timing properties and emissions from pulsar-wind nebulae and their pulsars, we studied the power-law component of the X-ray emissions from 35 pulsar-wind nebulae that have a detected ...

The imprint of pulsar parameters on the morphology of Pulsar Wind Nebulae [PDF]

, 2016
The morphology of young Pulsar Wind Nebulae (PWN) is largely determined by the properties of the wind injected by the pulsar. We have used a recent parametrization of the wind obtained from Force Free Electrodynamics simulations of pulsar magnetospheres ...

X-ray morphology of pulsar wind nebulae: the effect of local medium motion

ASTRONOMY AT THE EPOCH OF MULTIMESSENGER STUDIES. Proceedings of the VAK-2021 conference, Aug 23–28, 2021, 2022
The effect of the relative motion of the pulsar wind nebula (PWN) and the local medium on the PWN X-ray morphology isstudied using relativistic MHD modelling.

Slow motion pulsar wind nebulae

Journal of Physics: Conference Series, 2021
We show that even the slow (subsonic) motion of pulsar wind nebulae (PWNe) relative to an ambient matter has a significant impact on their observables. The motion changes the appearance of nebulae on X-ray images, comparing to what would be observed for ...

The contribution of Galactic TeV pulsar wind nebulae to Fermi-LAT diffuse emission

, 2021
The large-scale diffuse γ−ray flux observed by Fermi-LAT in the 1-100 GeV energy range, parameterized as ∝ E−Γ, has a spectral index Γ that depends on the distance from the Galactic center.

Pulsar Wind Nebulae in EGRET Error Boxes [PDF]

Astrophysics and Space Science, 2004
A remarkable number of pulsar wind nebulae (PWN) are coincident with EGRET gamma-ray sources. X-ray and radio imaging studies of unidentified EGRET sources have resulted in the discovery of at least 6 new pulsar wind nebulae (PWN).
