Bow Shocks from Neutron Stars: Scaling Laws and HST Observations of the Guitar Nebula [PDF]

open access: yes, 2002
The interaction of high-velocity neutron stars with the interstellar medium produces bow shock nebulae, where the relativistic neutron star wind is confined by ram pressure.

Bow shocks around pulsars and neutron stars

open access: yes, 2005
Pulsar wind nebulae are now well established as important probes both of neutron stars' relativistic winds and of the surrounding interstellar medium.

Modelling the evolution of pulsar wind nebulae

open access: yesSuid-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.

Improved Measurements of the IXPE Crab Polarization

open access: yesThe Astrophysical Journal, 2023
X-ray polarization from the Imaging X-ray Polarimetry Explorer (IXPE) provides an important new probe of the geometry of the pulsar emission zone and of particle acceleration in the surrounding pulsar wind nebula.

Multidimensional relativistic MHD simulations of Pulsar Wind Nebulae: dynamics and emission

open access: yes, 2017
Pulsar Wind Nebulae, and the Crab nebula in particular, are the best cosmic laboratories to investigate the dynamics of magnetized relativistic outflows and particle acceleration up to PeV energies.

MHD Interaction of Pulsar Wind Nebulae with SNRs and the ISM

open access: yes, 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.

Anticorrelation Between Flux and Photon Index of Hard-X-Ray Emission from the Crab

open access: yesThe Astrophysical Journal
Using Swift Burst Alert Telescope event-mode data during gamma-ray burst occurrences, we conduct spectral analysis for the Crab system. From 38 good observations, which span a period of 18 yr from 2006 to 2023, we find that the Crab’s X-ray flux not only

The IXPE Science of Pulsars and Their Nebulae

open access: yesGalaxies
Pulsars (PSRs) and Pulsar Wind Nebulae (PWNe) form some of the most interesting high-energy astrophysical systems. Their prominent synchrotron emission makes them ideal candidates for polarimetry.

Fermi-LAT Search for Pulsar Wind Nebulae around gamma-ray Pulsars

open access: yes, 2010
The high sensitivity of the Fermi-LAT (Large Area Telescope) offers the first opportunity to study faint and extended GeV sources such as pulsar wind nebulae (PWNe). After one year of observation the LAT detected and identified three pulsar wind nebulae:

Halo fraction in TeV-bright pulsar wind nebulae

open access: yesAstronomy & Astrophysics, 2020
The discovery of extended TeV emission around the Geminga and PSR B0656+14 pulsars, with properties consistent with free particle propagation in the interstellar medium (ISM), has led to the suggestion of “TeV halos” as a separate source class, which is ...
