The radiative X-ray and gamma-ray efficiencies of rotation powered pulsars [PDF]

, 2010
We present a statistical analysis of the X-ray luminosity of rotation powered pulsars and their surrounding nebulae using the sample of Kargaltsev & Pavlov (2008) and we complement this with an analysis of the gamma-ray-emission of Fermi detected pulsars.

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),

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 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 ...

The nature of the X-ray filaments around bow shock pulsar wind nebulae [PDF]

Astronomy & Astrophysics
We propose that the X-ray filaments emerging from selected bow shock pulsar wind nebulae are due to a charge-separated outflow of electrons and/or positrons escaping the nebula and propagating along the local Galactic magnetic field. The X-ray brightness,

GEMINGA’S PUZZLING PULSAR WIND NEBULA [PDF]

The Astrophysical Journal, 2017
ABSTRACT We report on six new Chandra observations of the Geminga pulsar wind nebula (PWN). The PWN consists of three distinct elongated structures—two ≈ 0.2 d

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 ×
