A Catalog of Pulsar X-Ray Filaments

The Astrophysical Journal
We present the first Chandra X-ray Observatory (CXO) catalog of “pulsar X-ray filaments,” or “misaligned outflows.” These are linear, synchrotron-radiating features powered by ultrarelativistic electrons and positrons that escape from bow shock pulsars ...

X-Ray Polarization Detection of the Pulsar Wind Nebula in G21.5–0.9 with IXPE

The Astrophysical Journal
We present the X-ray polarization observation of G21.5−0.9, a young Galactic supernova remnant (SNR), conducted with the Imaging X-ray Polarimetry Explorer (IXPE) in 2023 October, with a total livetime of approximately 837 ks.

Measurement of Neutral Atmosphere Density during the Years of Increasing Solar Activity Using Insight-HXMT Data with the Earth Occultation Technique

The Astrophysical Journal
The density of the Earth’s middle and upper atmosphere is an important parameter in Earth science and plays a critical role in the design, operation, and orbital determination of low Earth orbit spacecraft.

Unraveling the Nature of HAWC J1844–034 with Fermi-LAT Data Analysis and Multiwavelength Modeling

The Astrophysical Journal
The extended ultra-high-energy (UHE) gamma-ray source HAWC J1844–034 is closely associated with two other sources, HAWC J1843–032 and HWC J1846–025. Moreover, other gamma-ray observatories like HESS, LHAASO, and Tibet AS _γ have detected UHE gamma-ray ...
