Neutral Atmospheric Density Measurement Using Insight-HXMT Data by the Earth Occultation Technique
The Astrophysical Journal Supplement Series, 2022 The Earth occultation technique has broad applications in both astronomy and atmospheric density measurements. We construct the background model during the occultation of the Crab Nebula observed by the Insight-Hard X-ray Modulation Telescope (Insight ...

Material mixing in pulsar wind nebulae of massive runaway stars [PDF]
Monthly notices of the Royal Astronomical SocietyIn this study we quantitatively examine the manner pulsar wind, supernova ejecta and defunct stellar wind materials distribute and melt together into plerions.

DA 495: An Aging Pulsar Wind Nebula [PDF]
The Astrophysical Journal, 2008 We present a radio continuum study of the pulsar wind nebula (PWN) DA 495 (G65.7+1.2), including images of total intensity and linear polarization from 408 to 10550 MHz based on the Canadian Galactic Plane Survey and observations with the Effelsberg 100-m Radio Telescope.

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 ...

Fermi-LAT Detection of the Supernova Remnant G312.4-0.4 in the Vicinity of 4FGL J1409.1-6121e
The Astrophysical Journal, 2023 Gamma-ray emission provides constraints on the nonthermal radiation processes at play in astrophysical particle accelerators. This allows both the nature of accelerated particles and the maximum energy that they can reach to be determined.

Probing the Pulsar Wind Nebula of PSR B0355+54 [PDF]
, 2006 We present XMM-Newton and Chandra X-ray observations of the middle-aged radio pulsar PSR B0355+54. Our X-ray observations reveal emission not only from the pulsar itself, but also from a compact diffuse component extending ~50'' in the opposite direction

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.

International Astronomical Union Colloquium, 1996 AbstractI discuss pulsar wind nebulae for which ram pressure from the neutron star’s motion is a key element of the morphology. These PWN are tools for determining the pulsar distance, radial velocity component, and interaction of pulsar winds with surrounding media. The Guitar Nebula pulsar (B2224+65) also represents a ‘smoking gun’ for velocity kicks

The Observer’s Guide to the Gamma‐Ray Burst Supernova Connection
Advances in Astronomy, Volume 2017, Issue 1, 2017., 2017 We present a detailed report of the connection between long‐duration gamma‐ray bursts (GRBs) and their accompanying supernovae (SNe). The discussion presented here places emphasis on how observations, and the modelling of observations, have constrained what we know about GRB‐SNe.
