GECAM Localization of High Energy Transients and the Systematic Error
Yi Zhao, Wang-Chen Xue, Shao-Lin Xiong +63
Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) is a pair of microsatellites (i.e. GECAM-A and GECAM-B) dedicated to monitoring gamma-ray transie…
Search for Quasi-Periodical Oscillations in Precursors of Short and Long Gamma Ray Bursts
Shuo Xiao, Wen-Xi Peng, Shuang-Nan Zhang +23
The precursors of short and long Gamma Ray Bursts (SGRBs and LGRBs) can serve as probes of their progenitors, as well as shedding light on the physical processes of mergers or core…
A Localization Method of High Energy Transients for All-Sky Gamma-Ray Monitor
Yi Zhao, Wangchen Xue, Shaolin Xiong +62
Fast and reliable localization of high-energy transients is crucial for characterizing the burst properties and guiding the follow-up observations. Localization based on the relati…
An Insight-HXMT view of the mHz quasi-regular modulation phenomenon in the black hole X-ray binary 4U 1630-47
Zi-Xu Yang, Liang Zhang, Yue Huang +97
Here we report the spectral-timing results of the black hole X-ray binary 4U 1630-47 during its 2021 outburst using observations from the Hard X-ray Modulation Telescope. Type-C qu…
Tidally-induced Magnetar Super Flare at the Eve of Coalescence with Its Compact Companion
Zhen Zhang, Shu-Xu Yi, Shuang-Nan Zhang +2
In the late inspiral phase of a double neutron star (NS) or NS-black hole system in which one NS is a magnetar, the tidal force on the magnetar arisen from its companion will incre…
Revisit the periodicity of SGR J1935+2154 bursts with updated sample
Sheng-Lun Xie, Ce Cai, Shao-Lin Xiong +30
Since FRB 200428 has been found to be associated with an X-ray burst from the Galactic magnetar SGR J1935+2154, it is interesting to explore whether the magnetar bursts also follow…
The Peculiar Precursor of a Gamma-Ray Burst from a Binary Merger Involving a Magnetar
Shuo Xiao, Yan-Qiu Zhang, Zi-Pei Zhu +42
The milestone discovery of GW 170817-GRB 170817A-AT 2017gfo has shown that gravitational wave (GW) could be produced during the merger of neutron star-neutron star/black hole and t…
Insight-HXMT dedicated 33-day observation of SGR J1935+2154 II. Burst Spectral Catalog
Ce Cai, Shaolin Xiong, Lin Lin +21
Since April 28, 2020, Insight-HXMT has implemented a dedicated observation on the magnetar SGR J1935+2154. Thanks to the wide energy band (1-250 keV) and high sensitivity of Insigh…
Quasi-periodic oscillations of the X-ray burst from the magnetar SGR J1935+2154 and associated with the fast radio burst FRB 200428
Xiaobo Li, Mingyu Ge, Lin Lin +92
The origin(s) and mechanism(s) of fast radio bursts (FRBs), which are short radio pulses from cosmological distances, have remained a major puzzle since their discovery. We report…
Insight-HXMT dedicated 33-day observation of SGR J1935+2154 I. Burst Catalog
Ce Cai, Wangchen Xue, Chengkui Li +21
Magnetars are neutron stars with extreme magnetic field and sometimes manifest as soft gamma-ray repeaters (SGRs). SGR J1935+2154 is one of the most prolific bursters and the first…
The First Insight-HXMT Gamma-Ray Burst Catalog: The First Four Years
Xin-Ying Song, Shao-Lin Xiong, Shuang-Nan Zhang +40
The Hard X-ray Modulation Telescope (Insight-HXMT), is China's first X-ray astronomy satellite launched on June 15, 2017. The anti-coincidence CsI detectors of the High Energy X-ra…
The Second Catalog of Interplanetary Network Localizations of Konus Short Duration Gamma-Ray Bursts
D. Svinkin, K. Hurley, A. Ridnaia +72
We present the catalog of Interplanetary Network (IPN) localizations for 199 short-duration gamma-ray bursts (sGRBs) detected by the Konus-Wind (KW) experiment between 2011 January…
Insight-HXMT Detections of Hard X-ray Tails in Scorpius X-1
G. Q. Ding, J. L. Qu, L. M. Song +9
Using the observations of the high-energy (HE) detector of the Hard X-ray Modulation Telescope (Insight-HXMT) for Scorpius X-1 in 2018, we search for hard X-ray tails in the hard X…
Peculiar disk behaviors of the black hole candidate MAXI J1348-630 in the hard state observed by Insight-HXMT and Swift
W. Zhang, L. Tao, R. Soria +93
We present a spectral study of the black hole candidate MAXI J1348-630 during its 2019 outburst, based on monitoring observations with Insight-HXMT and Swift. Throughout the outbur…
