DA 495: An Aging Pulsar Wind Nebula [PDF]

The Astrophysical Journal, 2008
We present a radio continuum study of the pulsar wind nebula (PWN) DA 495 (G65.7+1.2), including images of total intensity and linear polarization from 408 to 10550 MHz based on the Canadian Galactic Plane Survey and observations with the Effelsberg 100-m Radio Telescope.

Slow motion pulsar wind nebulae

Journal of Physics: Conference Series, 2021
Abstract 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 a nebula at rest.

Pulsar Wind Nebulae [PDF]

International Astronomical Union Colloquium, 1996
Abstract I discuss pulsar wind nebulae for which ram pressure from the neutron star’s motion is a key element of the morphology. These PWN are tools for determining the pulsar distance, radial velocity component, and interaction of pulsar winds with surrounding media.

The Mouse Pulsar Wind Nebula [PDF]

The Astrophysical Journal, 2018
Abstract The young energetic pulsar J1747–2958 (τ = 26 kyr, erg s−1) powers the Mouse pulsar wind nebula (PWN), famous for its spectacular tail spanning 45″ in X-rays and 12′ in radio (d ∼ 5 kpc).

Gamma-ray emission from star-forming complexes observed by MAGIC: The cases of W51 and HESS J1857+026

EPJ Web of Conferences, 2015
Massive star-forming regions assemble a large number of young stars with remnants of stellar evolution and a very dense environment. Therefore, particles accelerated in supernova remnants and pulsar wind nebulae encounter optimal conditions for ...

High-resolution Radio Study of the Dragonfly Pulsar Wind Nebula Powered by PSR J2021+3651

The Astrophysical Journal, 2023
The Dragonfly Nebula (G75.2+0.1) powered by the young pulsar J2021+3651 is a rare pulsar wind nebula (PWN) that shows double tori and polar jets enclosed by a bow-shock structure in X-rays.

The Polarized Cosmic Hand: IXPE Observations of PSR B1509−58/MSH 15−52

The Astrophysical Journal, 2023
We describe IXPE polarization observations of the pulsar wind nebula (PWN) MSH 15−5 ^2 , the “Cosmic Hand.” We find X-ray polarization across the PWN, with B -field vectors generally aligned with filamentary X-ray structures.

Cosmic Ray production in SNRs of Pulsar Wind Nebulae type at different ages [PDF]

EPJ Web of Conferences, 2022
The overall observations of plerions from radio to the very high energy gamma-rays could provide information about the evolution of PWN from the young Crab-like to the older stages. The extended MeV-TeV emission from Geminga middle-aged pulsar of ~ 3.4 ×

THE THEORY OF PULSAR WIND NEBULAE [PDF]

International Journal of Modern Physics: Conference Series, 2014
I will review the current status of our theoretical understanding of Pulsar Winds and associated nebulae (PWNe). In recent years, axisymmetric models of pulsar winds with a latitude dependent energy flux have proved very successful at explaining the morphology of PWNe as seen in the X-rays.
