Pulsar wind nebulae created by fast-moving pulsars [PDF]
Journal of Plasma Physics, 2017 We review multiwavelength properties of pulsar wind nebulae created by supersonically moving pulsars and the effects of pulsar motion on the pulsar wind nebulae morphologies and the ambient medium. Supersonic pulsar wind nebulae are characterized by bow-shaped shocks around the pulsar and/or cometary tails filled with the shocked pulsar wind.

Solution to the sigma problem of pulsar wind nebulae [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2013 Abstract We present first results of 3D relativistic magnetohydrodynamical simulations of pulsar wind nebulae. They show that the kink instability and magnetic dissipation inside these nebulae may be the key processes allowing them to reconcile their observations with the theory of pulsar winds. In particular, the size of the termination

Pulsar Wind Nebulae in Egret Error Boxes [PDF]
Astrophysics and Space Science, 2005 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). Stationary PWN (SPWN) appear to be associated with steady EGRET sources with hard spectra, typical for gamma-ray pulsars ...

X-RAY EVOLUTION OF PULSAR WIND NEBULAE [PDF]
The Astrophysical Journal, 2010 During the search for counterparts of very-high-energy gamma-ray sources, we serendipitously discovered large, extended, low surface brightness emission from PWNe around pulsars with the ages up to ~100 kyrs, a discovery made possible by the low and stable background of the Suzaku X-ray satellite.

Supernova remnants pulsar wind nebulae and their interaction [PDF]
, 2001 A supernova explosion marks the end of the evolution of a massive star. What remains of the exploded star is a high density neutron star or a black hole. The material which has been ejected by the supernova explosion will manifest itself as a supernova remnant: a hot bubble of gas expanding in the interstellar medium.

Pulsar wind nebulae of runaway massive stars [PDF]
, 2022 International audienceA significant fraction of massive stars move at speed through the interstellar medium of galaxies. After their death as core-collapse supernovae, a possible final evolutionary state is that of a fast-rotating magnetized neutron star,

GEMINGA’S PUZZLING PULSAR WIND NEBULA [PDF]
The Astrophysical Journal, 2017 ABSTRACT We report on six new Chandra observations of the Geminga pulsar wind nebula (PWN). The PWN consists of three distinct elongated structures—two ≈ 0.2 d
