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…
Resolving the 2024 Outburst of Magnetar 1E 1841-045 from its host Supernova Remnant with EP-FXT
Yu-Cong Fu, Lin Lin, Yu-Jia Zheng +11
The magnetar 1E 1841-045 exhibited a new active episode starting on August 20, 2024, marked by X-ray bursts and enhanced persistent emission. Using data from the Einstein Probe (EP…
The orbital parameters of gamma-ray binary PSR~J2032+4127
Yu-Feng Luo, Shan-Shan Weng, Qing-Zhong Liu +6
PSR~J2032+4127 is the only one of gamma-ray binary, that exhibits pulsations in gamma-ray. Previous research has indicated that the pulsar and the Be star MT91 213 orbit each other…
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,…
