A Broadband X-Ray Study of the Rabbit Pulsar Wind Nebula Powered by PSR J1418-6058
The Astrophysical Journal, 2023 We report on broadband X-ray properties of the Rabbit pulsar wind nebula (PWN) associated with the pulsar PSR J1418−6058 using archival Chandra and XMM-Newton data, as well as a new NuSTAR observation.

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.

X-ray Emission from the Guitar Nebula [PDF]
, 1997 We have detected weak soft X-ray emission from the Pulsar Wind Nebula trailing the high velocity star PSR 2224+65 (the `Guitar Nebula'). This X-ray flux gives evidence of \gamma~10^7 eV particles in the pulsar wind and constrains the properties of the ...

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 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.

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.

Diverse Features of the Multiwavelength Afterglows of Gamma‐Ray Bursts: Natural or Special?
Advances in Astronomy, Volume 2016, Issue 1, 2016., 2016 The detection of optical rebrightenings and X‐ray plateaus in the afterglows of gamma‐ray bursts (GRBs) challenges the generic external shock model. Recently, we have developed a numerical method to calculate the dynamics of the system consisting of a forward shock and a reverse shock.

X‐Ray Pulsar Profile Recovery Based on Tracking‐Differentiator
Mathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016 The profile recovery is an important work in X‐ray pulsar‐based navigation. It is a key step for the analysis on the pulsar signal’s characteristic and the computing of time of arrival (TOA). This paper makes an argument for an algorithm based on the tracking‐differentiator (TD) to recover the profile from the low Signal‐to‐Noise Ratio (SNR) signals ...

MHD Interaction of Pulsar Wind Nebulae with SNRs and the ISM
, 2005 In the late 1960s the discovery of the Crab pulsar in its associated supernova remnant, launched a new field in supernova remnant research: the study of pulsar-driven or plerionic supernova remnants.

The Astrophysical Journal, 2023 HESS J1809–193 is an extended TeV γ -ray source and the origin of its γ -ray emission remains ambiguous. The pulsar wind nebula (PWN) of PSR J1J1809–193 lying inside the extended γ -ray emission is a possible candidate.
