Ultra-high-energy γ-ray emission associated with the tail of a bow-shock pulsar wind nebula. [PDF]
Innovation (Camb)In this study, we present a comprehensive analysis of an unidentified point-like ultra-high-energy (UHE) γ-ray source, designated as 1LHAASO J1740+0948u, situated in the vicinity of the middle-aged pulsar PSR J1740+1000.

Proton Acceleration with Relativistic Electromagnetic Shock. [PDF]
Adv Sci (Weinh)New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

A Pulsar Vector Observation-Based Link Acquisition Method for X-Ray Communications
International Journal of Aerospace Engineering, 2023 X-ray communication (XCOM) is an emerging laser communication technique for deep space applications. Traditional link acquisition of laser communications depends significantly on Earth support and shows little autonomy.

Discovery of an Ultra-fast X-ray Pulsar in the Supernova Remnant N157B [PDF]
, 1998 We present the serendipitous discovery of 16 ms pulsed X-ray emission from the Crab-like supernova remnant N157B in the Large Magellanic Cloud. This is the fastest spinning pulsar associated with a supernova remnant (SNR).
