Long-term timing evolution of four Anomalous X-Ray Pulsars
Han-Long Peng, Shan-Shan Weng, Ming-Yu Ge +9
Anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are believed to be manifestations of magnetars. Typically, AXPs exhibit higher X-ray luminosities, whereas SGRs a…

Secular Evolution of PSR J2021+4026: Long-Term γ-Ray Flux and Spin-Down Variability Beyond State Transitions
Xue-Zhi Liu, Ming-Yu Ge, Xiao-Ping Zheng +7
PSR J2021+4026 is a remarkable -ray pulsar exhibiting repeated transitions between high -ray flux (HGF) and low -ray flux (LGF) states. With 17-yr Fermi-LAT monitoring, we…
