Abstract |
The Chinese mission Insight-HXMT allows for a high sensitivity study of the X-ray sky in 1250 keV, thanks to a smart combination of collimated detectors operating in different energy bands and providing a source location accuracy of 1 arcmin. In addition to observing Galactic sources, the HXMT High Energy (HE) instrument also operates in the so-called GRB mode, that makess it possible to detect and characterize GRB prompt emission from 200 keV to 3 MeV with an effective area as high as 2000 cm2, thus filling the sensitivity gap of presently flying main GRB detectors in this energy range. We report the results of intensive simulations of the expected scientific performances of HXMT for GRB science, showing how, especially in combination with, e.g., Swift /BAT and Fermi /GBM, the HXMT measurements, will provide a significant improvement in the characterization of temporal and spectral properties of the prompt emission of long GRBs, as well as an improved detection rate and better spectral characterization of short GRBs. |
