The Second AGILE MCAL Gamma-Ray Burst Catalog: 13 yr of Observations" has been published in the Astrophysical Journal

08 February 2022

We are pleased to announce that "The Second AGILE MCAL Gamma-Ray Burst Catalog: 13 yr of Observations" has been published in the Astrophysical Journal: A. Ursi et al., ApJ 925 (2022).

This new catalog presents the results of a systematic search and analysis of Gamma-Ray Burst (GRBs) detected by the Astrorivelatore Gamma ad Immagini LEggero (AGILE) MiniCALorimeter (MCAL) in the energy band 0.4–100 MeV, over a time frame of 13 years, from November 2007 to November 2020. 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.

The AGILE MCAL GRB sample mostly consists of hard-spectrum GRBs, with a large fraction of short-duration events. The MCAL bursts details 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.

An on-line version of the 2nd AGILE MCAL GRB Catalog is also available as an interactive web table at the ASI Space Science Data Center (SSDC). The interactive webpage offers access to supplementary AGILE data products, such as: GRB MCAL lightcurves over 4 different timescales, hardness ratios, AGILE ratemeters lightcurves, and T50 and T90 lightcurve estimates.

For each event, the available supplementary data products can be visualized through the SSDC “GRB Explorer” tool.
