Despite over 50 years of research, many open questions remain about the origin and nature GRBs. Polarization measurements prompt emission these extreme phenomena have long been thought to be key answering a range questions. The POLAR detector was designed produce first set detailed reliable polarization in an energy approximately 50-500 keV. During late 2016 early 2017, detected total 55 Analysis results 5 GRBs reported past. were found consistent with low or unpolarized flux. However,...
In this work, we report the in-orbit demonstration of X-ray pulsar navigation with Insight-Hard Modulation Telescope (Insight-HXMT), which was launched on Jun. 15th, 2017. The new method 'Significance Enhancement Pulse-profile Orbit-dynamics' (SEPO) is adopted to determine orbit observations only one pulsar. test, Crab chosen and observed by Insight-HXMT from Aug. 31th Sept. 5th in Using 5-day-long observation data, determined successfully three telescopes onboard - High Energy (HE), Medium...
A sizeable fraction of gamma-ray burst (GRB) light curves (LCs) feature a sequence peaks that hold information on the unknown way energy is released and dissipated into gamma-rays over time. Traditionally, searches for periodic signals in GRB LCs have turned out to be inconclusive, partly because they are challenging as consequence short-lived, coloured-noise, non-stationary nature themselves. Yet, recent claims revived issue. We aim search components through new approach GRBs avoids most...
After 34 years, the black-hole candidate EXO 1846-031 went into outburst again in 2019. We investigate its spectral properties hard intermediate and soft states with NuSTAR Insight-HXMT. A reflection component has been detected two but possibly originating from different illumination spectra: state, illuminating source is attributed to a coronal component, which commonly observed other X-ray binaries, whereas state probably produced by disk self-irradiation. Both cases support as low...
A new black hole X-ray binary (BHXRB) MAXI J1535-571 was discovered by during its outburst in 2017. Using observations taken the first Chinese satellite, Hard Modulation Telescope (dubbed as Insight-HXMT), we perform a joint spectral analysis (2-150 keV) both energy and time domains. The spectra provide essential input for probing intrinsic Quasi-Periodic Oscillation (QPO) fractional rms (FRS). Our results show that intermediate state, are general consistent with those reported Swift/XRT...
The Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) satellite consists of two small satellites. Each GECAM payload contains 25 gamma ray detectors (GRD) and 8 charged particle (CPD). GRD is the main detector which can detect gamma-rays particles localize Gamma-Ray Bursts (GRB),while CPD used to help discriminate gamma-ray bursts bursts. makes use lanthanum bromide (LaBr3) crystal readout by SiPM. As all available SiPM devices belong commercial grade,...
