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.

The Pulsar Wind Nebula in G11.2−0.3
The Astrophysical Journal, 2003 We present an X-ray and radio study of the wind nebula surrounding the central pulsar PSR J1811-1925 in the supernova remnant G11.2-0.3. Using high resolution data obtained with the Chandra X-ray observatory and with the VLA radio telescope we show the X-ray and radio emission is asymmetric around the pulsar, despite the latter's central position in ...

Bow-shock pulsar-wind nebulae passing through density discontinuities [PDF]
, 2017 shock pulsar-wind nebulae are a subset of pulsar-wind nebulae that form when the pulsar has high velocity due to the natal kick during the supernova explosion.

A Spatially Resolved X-Ray Polarization Map of the Vela Pulsar Wind Nebula
The Astrophysical Journal Letters, 2023 In this paper, we present a full spatially resolved polarization map for the Vela pulsar wind nebula (PWN) observed by IXPE. By employing effective background discrimination techniques, our results show a remarkably high degree of local polarization in ...

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 ...

Impact of Cosmic‐Ray Physics on Dark Matter Indirect Searches
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 The quest for the elusive dark matter (DM) that permeates the Universe (and in general the search for signatures of physics beyond the Standard Model at astronomical scales) provides a unique opportunity and a tough challenge to the high energy astrophysics community.

Classical, large-scale 3D magneto-hydrodynamic simulations of interacting pulsar wind nebulae
Astronomy & AstrophysicsContext. Magnetised rotating neutron stars, or pulsars, are a possible end product of massive star evolution. Their relativistic wind successively interacts with the supernova ejecta of their defunct progenitor, then with the circumstellar medium of the ...

The Observer’s Guide to the Gamma‐Ray Burst Supernova Connection
Advances in Astronomy, Volume 2017, Issue 1, 2017., 2017 We present a detailed report of the connection between long‐duration gamma‐ray bursts (GRBs) and their accompanying supernovae (SNe). The discussion presented here places emphasis on how observations, and the modelling of observations, have constrained what we know about GRB‐SNe.

Pulsar wind nebulae meeting the circumstellar medium of their progenitors [PDF]
International audienceA 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 magnetized, rotating neutron star (a pulsar) is usually their ...
