cds-question@unistra.frgamma-ray-astronomygamma-ray-burstsWe present the results of a systematic search and analysis of GRBs detected by the Astrorivelatore Gamma ad Immagini LEggero (AGILE) MiniCALorimeter (MCAL; 0.4-100MeV) over a time frame of 13yr, from 2007 to 2020 November. The MCAL GRB sample consists of 503 bursts triggered by MCAL, 394 of which were fully detected onboard with high time resolution. The sample consists of about 44% short GRBs and 56% long GRBs. In addition, 109 bursts triggered partial MCAL onboard data acquisitions, providing further detections that can be used for joint analyses or triangulations. More than 90% of these GRBs were also detected by the AGILE Scientific RateMeters (RMs), providing simultaneous observations between 20keV and 100MeV. We performed spectral analysis of these events in the 0.4-50MeV energy range. We could fit the time-integrated spectrum of 258 GRBs with a single power-law model, resulting in a mean photon index <{beta}> of-2.3. Among them, 43 bursts could also be fitted with a Band model, with peak energy above 400 keV, resulting in a mean low-energy photon index <{alpha}>=-0.6, a mean high-energy photon index <{beta}>=-2.5, and a mean peak energy <Ep>=640keV. The AGILE MCAL GRB sample mostly consists of hard-spectrum GRBs, with a large fraction of short-duration events. We discuss properties and features of the MCAL bursts, whose detections can be used to perform joint broad-band analysis with other missions, and to provide insights on the high-energy component of the prompt emission in the tens of mega electron volt energy range.2022ApJ...925..152Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/925/152CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/156/217 : IPN supplement to BATSE untriggered GRBs (Hurley+, 2005)J/ApJS/191/179 : IPN supplement to the BeppoSAX GRB catalog (Hurley+, 2010)J/ApJS/197/34 : The IPN supplement to the HETE-2 GRB catalog (Hurley+, 2011)J/A+A/530/A21 : Spectral properties of 438 GRBs (Nava+, 2011)J/A+A/553/A33 : AGILE Mini-Calorimeter {gamma}-ray burst cat.
