GRB 231205B: AGILE detection
Abstract
The AGILE satellite detected the GRB 231205B at T0 = 2023-12-05 16:43:59 s (UTC), reported by Swift (GCNs #35269, #35275, #35291) and GECAM-B (GCN #35279). The burst is clearly visible in the AGILE scientific ratemeters of the MiniCALorimeter (MCAL; 0.4-100 MeV), and AntiCoincidence (AC; 50-200 keV) detectors. The event lasted about 18 s and it released a total number of 11057 counts in the MCAL detector (above a background rate of 539 Hz) and 54466 counts in the AC-Top detector (above a background rate of 2889 Hz). In the scientific ratemeters of the AC-Top detector is visible a GRB precursor, centered around -25 s to the Swift T0 and lasting 10 seconds.
