Pulsar Wind Nebulae

open access: yes, 2022
Pulsar Wind Nebulae (PWNe), structures powered by energetic pulsars, are known for their detection across the entire electromagnetic spectrum, with diverse morphologies and spectral behaviour between these bands.

Evolution of High-energy Electron Distribution in Pulsar Wind Nebulae

Research in Astronomy and Astrophysics
In this paper, we analyze the spectral energy distributions of 17 powerful (with a spin-down luminosity greater than 1035 erg s−1) young (with an age less than 15,000 yr) pulsar wind nebulae (PWNe) using a simple time-independent one-zone emission model.

Spatio-spectral-temporal modelling of two young pulsar wind nebulae

Monthly notices of the Royal Astronomical Society
Recent observations of a few young pulsar wind nebulae (PWNe) have revealed their morphologies in some detail. Given the availability of spatio-spectral-temporal data, we use our multi-zone (1D) leptonic emission code to model the PWNe associated with ...

Analysis of the possible detection of the pulsar wind nebulae of PSR J1208-6238, J1341-6220, J1838-0537, and J1844-0346

Astronomy & Astrophysics
Pulsar wind nebulae (PWNe) are a source of very high energy radiation that can reach up to tera-electron volts and even peta-electron volts. Our work uses the pulsar tree, a graph theory tool recently presented to analyze the pulsar population and select

Pulsar-wind nebulae meeting the circumstellar media of their progenitors

Astronomy & Astrophysics
A significative fraction of high-mass stars sail away through the interstellar medium of the galaxies. Once they evolved and died via a core-collapse supernova, a magnetised, rotating neutron star (a pulsar) is usually left over.

Radio and X-ray spectral properties of Gamma-ray bursts and Pulsar wind nebulae

Monthly notices of the Royal Astronomical Society, 2021
Both gamma-ray bursts (GRBs) and pulsar wind nebula (PWNe) are energetic outflows which are produced in powerful high energy astrophysical environments.

Reverberation of the Vela PULSAR WIND NEBULA

Письма в Астрономический журнал: Астрономия и космическая астрофизика, 2023
Transonic (withMach numberMs 1) motion of a pulsar relative to the external medium canhelp its compact pulsar wind nebula develop a double-torus X-ray morphology. The double-torus structurecan reverberate as a whole under the dynamic pressure of the external flow. For a flow aligned with thesymmetry axis of the nebula, the response of the double-torus
