| 英文摘要 | "At 20:43:31.19 UT on 25 January 2020, the Fermi Gamma-Ray Burst Monitor (GBM) triggered and located GRB 200125B (trigger 601677816 / 200125864) (Fermi GBM Team, GCN #26879), which was also detected by Insight-HXMT/HE (Cai et al., GCN #26888). The GBM light curve consists of multiple overlapping pulses with a duration (T90) of about 5.8 s (50-300 keV). The time-averaged spectrum from T0 s to T0+12 s is best fit by a Band function with Epeak = 175 +/- 3 keV, alpha = -0.74 +/- 0.01, and beta = -2.23 +/- 0.02. The event fluence (10-1000 keV) in this time interval is (5.48 +/- 0.03)E-5 erg/cm^2. The 1-sec peak photon flux measured starting from T0+1.3 s in the 10-1000 keV band is 103.7 +/- 0.6 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog: https://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html For Fermi GBM data and info, please visit the official Fermi GBM Support Page: https://fermi.gsfc.nasa.gov/ssc/data/access/gbm/" |
