Insight-HXMT observations of Swift J0243.6+6124: the evolution of RMS pulse fractions at super-Eddington luminosity
P. J. Wang, L. D. Kong, S. Zhang +116
Based on Insight-HXMT data, we report on the pulse fraction evolution during the 2017-2018 outburst of the newly discovered first Galactic ultraluminous X-ray source (ULX) Swift J0…
X-ray reprocessing in accreting pulsar GX 301-2 observed with Insight-HXMT
L. Ji, V. Doroshenko, V. Suleimanov +100
We investigate the absorption and emission features in observations of GX 301-2 detected with Insight-HXMT/LE in 2017-2019. At different orbital phases, we found prominent Fe Kalph…
Insight-HXMT observations of a possible fast transition from jet to wind dominated state during a huge flare of GRS~1915+105
L. D. Kong, S. Zhang, Y. P. Chen +92
We present the analysis of the brightest flare that was recorded in the \emph{Insight}-HMXT data set, in a broad energy range (2200 keV) from the microquasar GRS~1915+105 during…
Physical origin of the nonphysical spin evolution of MAXI J1820+070
J. Guan, L. Tao, J. L. Qu +91
We report on the Insight-HXMT observations of the new black hole X-ray binary MAXI J1820+070 during its 2018 outburst. Detailed spectral analysis via the continuum fitting method s…
GRB 200415A: A Short Gamma-Ray Burst from a Magnetar Giant Flare?
Jun Yang, Vikas Chand, Bin-Bin Zhang +16
The giant flares of soft gamma-ray repeaters (SGRs) have long been proposed to contribute to at least a subsample of the observed short gamma-ray bursts (GRBs). In this paper, we p…
Timing analysis of the black hole candidate EXO 1846-031 with Insight-HXMT monitoring
He-Xin Liu, Yue Huang, Guang-Cheng Xiao +118
We present the observational results from a detailed timing analysis of the black hole candidate EXO 1846-031 during its outburst in 2019 with the observations of Insight-HXMT, NIC…
Discovery of oscillations above 200 keV in a black hole X-ray binary with Insight-HXMT
Xiang Ma, Lian Tao, Shuang-Nan Zhang +119
Low-frequency quasi-periodic oscillations (LFQPOs) are commonly found in black hole X-ray binaries, and their origin is still under debate. The properties of LFQPOs at high energie…
The POLAR Gamma-Ray Burst Polarization Catalog
Merlin Kole, Nicolas De Angelis, Francesco Berlato +18
Despite over 50 years of research, many open questions remain about the origin and nature of GRBs. Polarization measurements of the prompt emission of these extreme phenomena have…
Constraining the transient high-energy activity of FRB180916.J0158+65 with Insight-HXMT followup observations
C. Guidorzi, M. Orlandini, F. Frontera +96
A link between magnetars and fast radio burst (FRB) sources has finally been established. In this context, one of the open issues is whether/which sources of extra galactic FRBs ex…
FRB 200428: an Impact between an Asteroid and a Magnetar
Jin-Jun Geng, Bing Li, Long-Biao Li +3
A fast radio burst (FRB) was recently detected to be associated with a hard X-ray burst from the Galactic magnetar SGR 1935+2154. Scenarios involving magnetars for FRBs are hence h…
Calibration of the Instrumental Response of Insight-HXMT/HE CsI Detectors for Gamma-Ray Monitoring
Qi Luo, Jin-Yuan Liao, Xu-Fang Li +17
The CsI detectors of the High Energy X-ray Telescope of the Hard X-ray Modulation Telescope (HXMT/CsI) can be used for gamma-ray all sky monitoring and searching for the electromag…
No pulsed radio emission during a bursting phase of a Galactic magnetar
L. Lin, C. F. Zhang, P. Wang +45
Fast radio bursts (FRBs) are mysterious millisecond-duration radio transients of unknown origin observed at extragalactic distances. It has been long speculated that magnetars are…
Discovery of delayed spin-up behavior following two large glitches in the Crab pulsar, and the statistics of such processes
M. Y. Ge, S. N. Zhang, F. J. Lu +130
Glitches correspond to sudden jumps of rotation frequency () and its derivative () of pulsars, the origin of which remains not well understood yet, partly because the jum…
A search for prompt gamma-ray counterparts to fast radio bursts in the Insight-HXMT data
C. Guidorzi, M. Marongiu, R. Martone +118
No robust detection of prompt electromagnetic counterparts to fast radio bursts (FRBs) has yet been obtained, in spite of several multi-wavelength searches carried out so far. Spec…
Switches between accretion structures during flares in 4U 1901+03
