Discovery of Short-Term γ-Ray Pulsed Radiation Variations Following a Glitch in PSR J0205+6449

Wen-Tao Ye, Mingyu Ge, Shi-Jie Zheng, Xiang Ma et autres

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 glitches. To date, pulsed radiation changes associated with glitches have only been detected in the radio band. …

Timing and Spectral Studies of PSR J2022+3842 with NICER and NuSTAR

Jia-Ning Hu, X. H. Li, Xian-Ao Wang, Han-Long Peng et autres

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 from joint observations with NICER and the Nuclear Spectroscopic Telescope Array (NuSTAR). Two large glitches are identified …

Comprehensive Measurement of Spectral Evolution in a Gamma-Ray Burst Flare: High-time-resolution Insights into the “Double-tracking” Phenomenon

Zheng-Hang Yu, Wen-Jun Tan, Chen-Wei Wang, Shao-Lin Xiong et autres

Abstract The spectral evolution characteristics of the prompt emission in gamma-ray bursts (GRBs) have been extensively studied, but detailed investigations of the spectral evolution in a GRB flare remain lacking. In this work, we present the first analysis of spectral parameter evolution …

GECAM discovery of a peculiar magnetar X-ray burst (MXB 221120) from SGR J1935+2154 associated with a fast radio burst

Wen-Jun Tan, Yue Wang, Chen-Wei Wang, Shao-Lin Xiong et autres

Fast radio bursts (FRBs) are enigmatic cosmic transients of millisecond duration observed in the radio band. The identification of FRB-associated magnetar X-ray bursts (MXBs) from galactic magnetar SGR J1935+2154 suggests that at least a fraction of FRBs can be produced from magnetar …

Systematic study of the simultaneous events detected by GECAM

Yang-Zhao Ren, F. R. Zhu, Shao-Lin Xiong, Yu Zhang et autres

Gravitational-wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) is a constellation of all-sky monitors in hard X-ray and gamma-ray bands, primarily observing high-energy transients such as gamma-ray bursts, soft gamma-ray repeaters, solar flares, and terrestrial gamma-ray flashes. As GECAM has the highest temporal …

Long-term Timing Evolution of Four Anomalous X-Ray Pulsars

Hongling Peng, Shanshan Weng, M. Y. Ge, Shiqi Zhou et autres

Abstract 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 are generally fainter and display significantly high signal-to-noise ratios only during their outburst phases. In this work, …

GECAM discovery of the second FRB-associated Magnetar X-ray Burst from SGR J1935+2154

Chen-Wei Wang, Shao-Lin Xiong, Yue Wang, Wen-Jun Tan et autres

Fast radio burst (FRB) is mysterious phenomenon with millisecond-duration radio pulses observed mostly from cosmological distance. The association between FRB 200428 and a magnetar X-ray burst (MXB) from SGR J1935+2154 has significantly advanced the understanding of FRB and magnetar bursts. However, it …
