In-flight Timing Calibration of the Follow-up X-Ray Telescope on Board the Einstein Probe
Juan Zhang, Xiaofan Zhao, Dawei Han +18
After the launch of Einstein Probe (EP), pulsars are observed to calibrate the timing system of the onboard Follow-up X-ray Telescope (FXT) by measuring the times of arrival (TOAs)…
Discovery of Short-Term γ-Ray Pulsed Radiation Variations Following a Glitch in PSR J0205+6449
Wen-Tao Ye, Ming-Yu Ge, Shi-Jie Zheng +7
Rotation-powered pulsars exhibit stable emission characteristics most of the time. However, their radiative state can vary with the sudden changes of rotational state such as glitc…
Timing and Spectral Studies of PSR J2022+3842 with NICER and NuSTAR
Jia-Ning Hu, Xiang-Hua Li, Xian-Ao Wang +6
We report on the long-term timing analysis of PSR J2022+3842 using observations from the Neutron Star Interior Composition Explorer (NICER), along with spectral properties derived…
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…
