Turbulent Diffusion of the Particles within Pulsar Wind Nebulae
The Astrophysical Journal, 2023 A turbulent diffusion model is presented to account for the energy and spatial diffusion of the particles within pulsar wind nebulae (PWNe), with the assumption that the energy injected from the pulsar into the nebula is split between the turbulence ...

Radio Study of the Pulsar Wind Nebula Powered by PSR B1706-44
The Astrophysical Journal, 2023 PSR B1706−44 is an energetic gamma-ray pulsar located inside supernova remnant (SNR) G343.1−2.3 and it powers a compact pulsar wind nebula (PWN) that shows torus and jet structure in X-rays.

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),

Supernova remnants in nearby galaxies
Astronomische Nachrichten, Volume 341, Issue 2, Page 156-162, February 2020., 2020 Abstract Supernova remnants (SNRs) are the aftermath of stellar explosions, which inject large amounts of energy into the interstellar medium (ISM), carving out new structures and transferring kinetic energy to the ISM. They also act as recycling centers, which return elements processed in stars to the ISM, and cosmic particle accelerators.

A Spatially Resolved X-Ray Polarization Map of the Vela Pulsar Wind Nebula
The Astrophysical Journal Letters, 2023 In this paper, we present a full spatially resolved polarization map for the Vela pulsar wind nebula (PWN) observed by IXPE. By employing effective background discrimination techniques, our results show a remarkably high degree of local polarization in ...

Magnetic Reconnection in the Space Sciences: Past, Present, and Future
Journal of Geophysical Research: Space Physics, Volume 125, Issue 2, February 2020., 2020 Abstract Magnetic reconnection converts, often explosively, stored magnetic energy to particle energy in space and in the laboratory. Through processes operating on length scales that are tiny, it facilitates energy conversion over dimensions of, in some cases, hundreds of Earth radii.

A Study of Particle Transport in Young Pulsar Wind Nebulae
The Astrophysical Journal, 2023 The broadband emission of numerous pulsar wind nebula (PWNe) in our Galaxy can be well described by synchrotron radiation and inverse Compton scattering from relativistic particles, specifically electrons and positrons.

A new approach to generate a catalogue of potential historical novae
Astronomische Nachrichten, Volume 341, Issue 1, Page 79-98, January 2020., 2020 Abstract Ancient Chinese, Korean, and Vietnamese observers left us records of celestial sightings, the so‐called “guest stars” dated up to ∼2500 years ago. Their identification with modern observable targets could open interesting insights into the long‐term behavior of astronomical objects, as shown by the successful identification of eight galactic ...

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 ×
