Polarization of Intrabinary Shock Emission in Spider Pulsars

The Astrophysical Journal, 2023
In so-called spider pulsars, the X-ray band is dominated by intrabinary shock (IBS) synchrotron emission. While the double-peaked X-ray light curves from these shocks have been well characterized in several spider systems (both black widows and redbacks),

Gamma-ray emission from star-forming complexes observed by MAGIC: The cases of W51 and HESS J1857+026

EPJ Web of Conferences, 2015
Massive star-forming regions assemble a large number of young stars with remnants of stellar evolution and a very dense environment. Therefore, particles accelerated in supernova remnants and pulsar wind nebulae encounter optimal conditions for ...

High-resolution Radio Study of the Dragonfly Pulsar Wind Nebula Powered by PSR J2021+3651

The Astrophysical Journal, 2023
The Dragonfly Nebula (G75.2+0.1) powered by the young pulsar J2021+3651 is a rare pulsar wind nebula (PWN) that shows double tori and polar jets enclosed by a bow-shock structure in X-rays.

Cosmic Ray production in SNRs of Pulsar Wind Nebulae type at different ages [PDF]

EPJ Web of Conferences, 2022
The overall observations of plerions from radio to the very high energy gamma-rays could provide information about the evolution of PWN from the young Crab-like to the older stages. The extended MeV-TeV emission from Geminga middle-aged pulsar of ~ 3.4 ×

THE THEORY OF PULSAR WIND NEBULAE [PDF]

International Journal of Modern Physics: Conference Series, 2014
I will review the current status of our theoretical understanding of Pulsar Winds and associated nebulae (PWNe). In recent years, axisymmetric models of pulsar winds with a latitude dependent energy flux have proved very successful at explaining the morphology of PWNe as seen in the X-rays.

The Polarized Cosmic Hand: IXPE Observations of PSR B1509−58/MSH 15−52

The Astrophysical Journal, 2023
We describe IXPE polarization observations of the pulsar wind nebula (PWN) MSH 15−5 ^2 , the “Cosmic Hand.” We find X-ray polarization across the PWN, with B -field vectors generally aligned with filamentary X-ray structures.

Impact of Cosmic‐Ray Physics on Dark Matter Indirect Searches

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
The quest for the elusive dark matter (DM) that permeates the Universe (and in general the search for signatures of physics beyond the Standard Model at astronomical scales) provides a unique opportunity and a tough challenge to the high energy astrophysics community.

Classical, large-scale 3D magneto-hydrodynamic simulations of interacting pulsar wind nebulae

Astronomy & Astrophysics
Context. Magnetised rotating neutron stars, or pulsars, are a possible end product of massive star evolution. Their relativistic wind successively interacts with the supernova ejecta of their defunct progenitor, then with the circumstellar medium of the ...
