Since its launch in 2008, the Fermi Gamma-ray Burst Monitor (GBM) has triggered and located on average approximately two γ-ray bursts (GRBs) every three days. Here, we present the third of a series of catalogs of GRBs detected by GBM, extending the second catalog by two more years through the middle of 2014 July. The resulting list includes 1405 triggers identified as GRBs. The intention of the GBM GRB catalog is to provide information to the community on the most important observables of the GBM-detected GRBs. For each GRB, the location and main characteristics of the prompt emission, the duration, peak flux, and fluence are derived. The latter two quantities are calculated for the 50–300 keV energy band where the maximum energy release of GRBs in the instrument reference system is observed, and also for a broader energy band from 10 to 1000 keV, exploiting the full energy range of GBM's low-energy [Nai[Tl)] detectors. Using statistical methods to assess clustering, we find that the hardness and duration of GRBs are better fit by a two-component model with short-hard and long-soft bursts than by a model with three components. Furthermore, information is provided on the settings and modifications of the triggering criteria and exceptional operational conditions during years five and six in the mission. This third catalog is an official product of the Fermi GBM science team, and the data files containing the complete results are available from the High-Energy Astrophysics Science Archive Research Center.

The THESEUS space mission concept: science case, design and expected performances (2017, background): “Assuming Fcore ∼10 ph cm−2 s−1 (e.g. Narayana Bhat et al., 2016), since short GRBs have a median redshift of z ∼ 0.5 (Berger, 2014), at a distance of ∼ 400 Mpc Fcore would be ∼ 103 ph cm−2 s−1, thus even assuming a steep dependence of F from Θview (e.g. s = 6) a nearby short GRB can be detected…”
The Fourth Fermi-GBM Gamma-Ray Burst Catalog: A Decade of Data (2020, background): “…duration distributions are best described by a two component model corresponding to the short and long GRB categories (see Figure 4), which reaffirms the study of Bhat et al. (2016) which didn’t provide any clue for an extra class, like soft-intermediate duration GRBs bridging the other two groups.”
An Ordinary Short Gamma-Ray Burst with Extraordinary Implications: Fermi-GBM Detection of GRB 170817A (2017, methodology): “Figure 5(a) shows the T90 duration distribution of GRBs that triggered GBM through 2014 July 11 (Bhat et al. 2016).”
