Pulsar wind nebulae of runaway massive stars [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2022
ABSTRACT A significant fraction of massive stars move at speed through the interstellar medium of galaxies. After their death as core-collapse supernovae, a possible final evolutionary state is that of a fast-rotating magnetized neutron star, shaping its circumstellar medium into a pulsar wind nebula.

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.

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 ...

Potential Contribution of Young Pulsar Wind Nebulae to Galactic High-energy Neutrino Emission

The Astrophysical Journal
Pulsar wind nebulae (PWNe), especially the young ones, are among the most energetic astrophysical sources in the Galaxy. It is usually believed that the spin-down energy injected from the pulsars is converted into magnetic field and relativistic ...

From young to old: The evolutionary path of Pulsar Wind Nebulae [PDF]

Publications Astronomical Society of Australia, 2023
Pulsar wind nebulae (PWN) are fascinating systems and archetypal sources for high-energy astrophysics in general. Due to their vicinity, brightness, to the fact that they shine at multi-wavelengths, and especially to their long-living emission at gamma ...

Reverberation of pulsar wind nebulae (III): Modelling of the plasma interface empowering a long term radiative evolution [PDF]

Monthly notices of the Royal Astronomical Society, 2023
The vast majority of Pulsar Wind Nebulae (PWNe) present in the Galaxy is formed by middle-aged systems characterized by a strong interaction of the PWN itself with the supernova remnant (SNR). Unfortunately, modelling these systems can be quite complex

The Pulsar Wind Nebulae contribution to gamma-rays [PDF]

Proceedings of 7th Heidelberg International Symposium on High-Energy Gamma-Ray Astronomy — PoS(Gamma2022), 2023
Pulsar Wind Nebulae (PWNe) shine at multi-wavelengths and are expected to constitute the largest class of gamma-ray sources in our Galaxy. They are known to be very efficient particle accelerators: the Crab nebula, the PWNe class prototype, is the unique

Reverberation of pulsar wind nebulae (II): Anatomy of the “thin-shell” evolution [PDF]

Monthly notices of the Royal Astronomical Society, 2023
During its early evolution, a pulsar wind nebula (PWN) sweeps the inner part of the supernova ejecta and forms a thin massive shell. Later on, when the shell has been reached by the reverse shock of the supernova remnant, the evolution becomes more ...
