A Catalog of Pulsar X-Ray Filaments

The Astrophysical Journal
We present the first Chandra X-ray Observatory (CXO) catalog of “pulsar X-ray filaments,” or “misaligned outflows.” These are linear, synchrotron-radiating features powered by ultrarelativistic electrons and positrons that escape from bow shock pulsars ...

A Key to Pulsar Wind Bubble Morphologies: HD simulations [PDF]

arXiv, 2003
We present a model of a pulsar-driven supernova remnant, by using a hydrodynamics code, which simulates the evolution of a pulsar wind nebula when the pulsar is moving at a high velocity through its expanding supernova remnant. The simulation shows four different stages of the pulsar wind nebula: the supersonic expansion stage, the reverse shock ...

First Detection of Polarization in X-Rays for PSR B0540-69 and Its Nebula

The Astrophysical Journal
We report on X-ray polarization measurements of the extragalactic Crab-like PSR B0540-69 and its Pulsar Wind Nebula (PWN) in the Large Magellanic Cloud, using a ∼850 ks Imaging X-ray Polarimetry Explorer (IXPE) exposure. The PWN is unresolved by IXPE. No

Lepton Acceleration in Pulsar Wind Nebulae [PDF]

, 2010
Pulsar Wind Nebulae (PWNe) act as calorimeters for the relativistic pair winds emanating from within the pulsar light cylinder. Their radiative dissipation in various wavebands is significantly different from that of their pulsar central engines: the broadband spectra of PWNe possess characteristics distinct from those of pulsars, thereby demanding a ...

2FHL J1745.1–3035: A Newly Discovered, Powerful Pulsar Wind Nebula Candidate

The Astrophysical Journal
We present a multi-epoch, multi-observatory X-ray analysis for 2FHL J1745.1–3035, a newly discovered very high-energy Galactic source detected by the Fermi Large Area Telescope (LAT) located in close proximity to the Galactic Center ( l = 358.°5319; b = −

Observations of Supernova Remnants and Pulsar Wind Nebulae: A VERITAS Key Science Project [PDF]

arXiv, 2009
The study of supernova remnants and pulsar wind nebulae was one of the Key Science Projects for the first two years of VERITAS observations. VERITAS is an array of four imaging Cherenkov telescopes located at the Whipple Observatory in southern Arizona. Supernova remnants are widely considered to be the strongest candidate for the source of cosmic rays
