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.

International Astronomical Union Colloquium, 1996 AbstractI 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 Guitar Nebula pulsar (B2224+65) also represents a ‘smoking gun’ for velocity kicks

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.

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.

Constraining models of the pulsar wind nebula in SNR G0.9+0.1 via simulation of its detection properties using the Cherenkov Telescope Array [PDF]
, 2020 SNR G0.9+0.1 is a well known source in the direction of the Galactic Center composed by a Supernova Remnant (SNR) and a Pulsar Wind Nebula (PWN) in the core.

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.

Do we really observe a bow shock in N157B...? [PDF]
, 2003 I present a model of a pulsar wind interacting with its associated supernova remnant. I will use the model to argue that one can explain the morphology of the pulsar wind nebula inside N157B, a supernova remnant in the Large Magellanic Cloud, without the need for a bow shock interpretation.

TeV Gamma-rays from the Northern Sky Pulsar Wind Nebulae [PDF]
J.Phys.G31:1465,2005, 2005 We estimate the TeV gamma-ray fluxes expected from the population of young pulsars in terms of the self-consistent time dependent hadronic-leptonic model for the high energy processes inside the pulsar wind nebulae. This radiation model bases on the hypothesis of Arons and collaborators who postulate that leptons are accelerated inside the nebulae as a

A deep X-ray spectral imaging of the bow-shock pulsar wind nebula associated with PSR B1929+10 [PDF]
Astronomy & Astrophysics, 2020 In this work, we study the X-ray bow-shock nebula powered by the mature pulsar PSR B1929+10 using data from XMM-Newton, with an effective exposure of ∼300 ks, offering the deepest investigation of this system thus far.

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 ...
