Search for gamma-ray bursts and gravitational wave electromagnetic counterparts with High Energy X-ray Telescope of Insight-HXMT

Abstract: The High Energy X-ray telescope (HE) on-board the Hard X-ray Modulation Telescope (Insight-HXMT) can serve as a wide Field of View (FOV) gamma-ray monitor with high time resolution (μs) and large effective area (up to thousands cm2). We developed a pipeline to search for Gamma-Ray Bursts (GRBs), using the traditional signal-to-noise ratio (SNR) method for blind search and the coherent search method for targeted search. By taking into account the location and spectrum of the burst and the detector response, the… Show more

“…Indeed, Insight-HXMT/HE has been served as a wide-field gamma-ray monitor for GRBs, mainly using the CsI detectors of HE Cai et al 2021). We find that some short GRBs (nominally with duration less than 2 s) would look similar to the SGR bursts in NaI detectors when they incident the HE telescope from the front side.…”

“…The blind search is based on the signal-to-noise ratio (i.e. SNR) method which has been applied to gamma-ray burst search in the HE CsI detectors of Insight-HXMT (see Cai et al (2021) for more details). This method is used to search for magnetar bursts in the HE NaI detectors of Insigth-HXMT.…”
