| 英文摘要 | Around the trigger time (T0=2020-04-30T21:43:00.5 UTC) of the highly polarised radio burst event reported by FAST (ATel #13699), Insight-HXMT was carrying out the ToO observation of SGR 1935+2154 without any occultation by the Earth. Within T0 +/- 50 s, no significant excess events (SNR > 3 sigma) are found in a search of the Insight-HXMT LE (1-10 keV), ME(10-30 keV) and HE (27-250 keV) light curves. Assuming the same spectral model to the X-ray counterpart that we reported in ATel #13687, and with one second timescale (1 s) coming from the position of SGR1935+2154, the 3-sigma fluence upper-limits are as following: Model: wabs*Cutoffpl (nH=2.6,PhoIndex=1.44, Ecut=69.8 keV): LE: 2.68e-09 erg cm^-2 ME: 3.45e-09 erg cm^-2 HE: 4.46e-09 erg cm^-2 Insight-HXMT will continue to observe SGR 1935+2154 with LE, ME and HE until 2020-05-06 01:20:47 UT. Insight-HXMT is the first Chinese space X-ray telescope, which was funded jointly by the China National Space Administration (CNSA) and the Chinese Academy of Sciences (CAS).
