Reverberation of the Vela Pulsar Wind Nebula

Письма в Астрономический журнал: Астрономия и космическая астрофизика, 2023
Transonic (withMach numberMs 1) motion of a pulsar relative to the external medium canhelp its compact pulsar wind nebula develop a double-torus X-ray morphology. The double-torus structurecan reverberate as a whole under the dynamic pressure of the external flow. For a flow aligned with thesymmetry axis of the nebula, the response of the double-torus

Analysis of γ-ray emission above 30 GeV from the LMC pulsar wind nebula N 157B with Fermi-LAT

Monthly notices of the Royal Astronomical Society, 2023
N 157B located in the large Magellanic Cloud is the first pulsar wind nebula detected outside of the Galaxy in γ-rays. In this paper, we analyse the emission above 30 GeV from N 157B using ∼14.3 yr of Fermi-LAT data.

Pulsars and Pulsar Wind Nebulae

2019
When heavy stars have burned all their nuclear fuel, neutron degeneracy pressure is the last force able to halt their collapse into a black hole. The sudden stop of the free-fall collapse leads to a rebound of the infalling matter triggering an outward shock that blows up the star envelope and powers a Type II supernova.

Neutron Stars, Pulsars, and Pulsar Wind Nebulae [PDF]

open access: possible, 2020
The connection between supernovae and neutron stars goes back to the seminal publications by W. Baade and F. Zwicky in 1934, in which they coined both the term “super-nova”, suggested a connection between cosmic rays and “super-novae” and postulated that a “super-nova” event “represents the transition of an ordinary star into a neutron star”.

Introduction to Pulsar Wind Nebulae

2018
The ejected material by a SN explosion interacts with the surrounding environment, giving rise to a new astrophysical object known as SNR (for a review of this matter, I refer the reader to (Reynolds 2008) and to Appendix A for more information on the first evolutionary phase).

Introduction to Pulsar Wind Nebulae

2016
Pulsar Wind Nebulae are nebulae of electrons and positrons powered by a central pulsar. In this chapter I give a detailed description of star evolution, centered on the description of supernova remnants, pulsars and pulsar wind nebulae. The basic properties of pulsars are explained, together with the emission mechanisms responsible for the production ...
