HESS J1632-478: an energetic relic [PDF]

, 2010
HESS J1632-478 is an extended and still unidentified TeV source in the galactic plane. In order to identify the source of the very high energy emission and to constrain its spectral energy distribution, we used a deep observation of the field obtained ...

Modelling the evolution of pulsar wind nebulae

Suid-Afrikaanse Tydskrif vir Natuurwetenskap en Tegnologie, 2013
Using numerical models, the influence of factors such as agnetic field strength on the evolution of pulsar wind ebulae can be determined. This includes the morphological evolution as well as the evolution of the type of light emitted and the corresponding intensity.

Polarization in the inner region of pulsar wind nebulae [PDF]

Astronomy & Astrophysics, 2005
We present here the first effort to compute synthetic synchrotron polarization maps of Pulsar Wind Nebulae (PWNe). Our goal is to highlight how polarization can be used as an additional diagnostic tool for the flow structure in the inner regions of these nebulae.

MHD models of Pulsar Wind Nebulae [PDF]

, 2010
Pulsar Wind Nebulae (PWNe) are bubbles or relativistic plasma that form when the pulsar wind is confined by the SNR or the ISM. Recent observations have shown a richness of emission features that has driven a renewed interest in the theoretical modeling of these objects.

The Vela Pulsar and its Synchrotron Nebula

, 2001
(Abridged) We present high-resolution Chandra X-ray observations of PSR B0833-45, the 89 ms pulsar associated with the Vela supernova remnant. We have acquired two observations separated by one month to search for changes in the pulsar and its ...

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 ...

Optical observations of PSR J2021+3651 in the Dragonfly Nebula with the GTC

, 2015
PSR J2021+3651 is a 17 kyr old rotation powered pulsar detected in the radio, X-rays, and $\gamma$-rays. It powers a torus-like pulsar wind nebula with jets, dubbed the Dragonfly, which is very similar to that of the Vela pulsar.
