The Discovery of Three Pulsars in the Globular Cluster M15 with FAST

The Astrophysical Journal Letters
We present the discovery of three pulsars in the globular cluster (GC) M15 (NGC 7078) by the Five-hundred-meter Aperture Spherical Radio Telescope. PSR J2129+1210J (M15J) is a millisecond pulsar with a spin period of 11.84 ms and a dispersion measure of ...

Probing Populations of Dark Stellar Remnants in the Globular Clusters 47 Tuc and Terzan 5 Using Pulsar Timing

The Astrophysical Journal
We present a new method to combine multimass equilibrium dynamical models and pulsar timing data to constrain the mass distribution and remnant populations of Milky Way globular clusters (GCs).

High-energy Emission from the Intrabinary Shocks in Redback Pulsars

The Astrophysical Journal
The intrabinary shocks (IBS) of spider pulsars emit nonthermal synchrotron X-rays from accelerated electrons and positrons in the shocked pulsar wind, likely energized by magnetic reconnection.

Anticorrelation Between Flux and Photon Index of Hard-X-Ray Emission from the Crab

The Astrophysical Journal
Using Swift Burst Alert Telescope event-mode data during gamma-ray burst occurrences, we conduct spectral analysis for the Crab system. From 38 good observations, which span a period of 18 yr from 2006 to 2023, we find that the Crab’s X-ray flux not only
