Bow-shock Pulsar Wind Nebulae Passing Through Density Discontinuities

, 2016
Bow-shock pulsar wind nebulae are a subset of pulsar wind nebulae that form when the pulsar has high velocity due to the natal kick during the supernova explosion.

Multi-D magnetohydrodynamic modelling of pulsar wind nebulae: recent progress and open questions [PDF]

, 2016
In the last decade, the relativistic magnetohydrodynamic (MHD) modelling of pulsar wind nebulae, and of the Crab nebula in particular, has been highly successful, with many of the observed dynamical and emission properties reproduced down to the finest ...

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers

Annalen der Physik, Volume 536, Issue 2, February 2024.
Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

The Dark Matter Annihilation Signal from Dwarf Galaxies and Subhalos

Advances in Astronomy, Volume 2010, Issue 1, 2010., 2010
Dark Matter annihilation holds great potential for directly probing the clumpiness of the Galactic halo that is one of the key predictions of the Cold Dark Matter paradigm of hierarchical structure formation. Here we review the γ‐ray signal arising from dark matter annihilation in the centers of Galactic subhalos.

Spectral signature of a free pulsar wind in the gamma-ray binaries LS 5039 and LSI +61$\degr$303 [PDF]

, 2008
LS 5039 and LSI +61$\degr$303 are two binaries that have been detected in the TeV energy domain. These binaries are composed of a massive star and a compact object, possibly a young pulsar.

TIME-DEPENDENT MODELING OF PULSAR WIND NEBULAE [PDF]

The Astrophysical Journal, 2013
A spatially independent model that calculates the time evolution of the electron spectrum in a spherically expanding pulsar wind nebula (PWN) is presented, allowing one to make broadband predictions for the PWN's non-thermal radiation. The source spectrum of electrons injected at the termination shock of the PWN is chosen to be a broken power law.

Optical Observations of PSR J0205+6449

, 2008
PSR J0205+6449 is a X-ray and radio pulsar in supernova remnant 3C 58. We report on observations of the central region of 3C 58 using the 4.2-m William Herschel Telescope with the intention of identifying the optical counterpart of PSR J0205+6449 and ...

Multi-wavelength observations of 2HWC J1928+177: dark accelerator or new TeV gamma-ray binary?

, 2020
2HWC J1928+177 is a Galactic TeV gamma-ray source detected by the High Altitude Water Cherenkov (HAWC) Observatory up to ~ 56 TeV. The HAWC source, later confirmed by H.E.S.S., still remains unidentified as a dark accelerator since there is no apparent ...
