• The 3rd AGILE Terrestrial Gamma Ray Flash Catalog. Part I: Association to Lightning Sferics 

      Lindanger, Anders; Marisaldi, Martino; Maiorana, Carolina; Sarria, David; Albrechtsen, Kjetil; Østgaard, Nikolai; Galli, M.; Ursi, Alessandro; Labanti, C.; Tavani, Marco; Pittori, C.; Verrecchia, F. (Journal article; Peer reviewed, 2020)
      We present a complete and systematic search for terrestrial gamma-ray flashes (TGFs), detected by AGILE, that are associated with radio sferics detected by the World Wide Lightning Location Network (WWLLN) in the period ...
    • The 3rd AGILE Terrestrial Gamma-ray Flashes Catalog. Part II: Optimized Selection Criteria and Characteristics of the New Sample 

      Maiorana, Carolina; Marisaldi, Martino; Lindanger, Anders; Østgaard, Nikolai; Ursi, Alessandro; Sarria, David; Galli, M.; Labanti, C.; Tavani, Marco; Pittori, C.; Verrecchia, F. (Journal article; Peer reviewed, 2020)
      We present in this work the third catalog of terrestrial gamma-ray flashes (TGFs) by the AGILE mission and the new search algorithm that was developed to produce it. We firstly introduce the new selection criteria, designed ...
    • Analysis of Thunderstorms Producing Terrestrial Gamma Ray Flashes With the Meteosat Second Generation 

      Ursi, Alessandro; Marisaldi, Martino; Dietrich, Stefano; Tavani, Marco; Tiberia, A; Porcu, Federico (Peer reviewed; Journal article, 2019)
      Up to now, only few works focused on the meteorological context leading to the production of Terrestrial Gamma ray Flashes (TGFs). In this study, we carry out, for the first time, an analysis on large scale of the ...
    • Detection of terrestrial gamma-ray flashes with the AGILE/MCAL 

      Ursi, Alessandro; Marisaldi, Martino; Tavani, Marco (Peer reviewed; Journal article, 2019)
      AGILE is one of the satellites currently detecting terrestrial gamma-ray flashes (TGFs). In particular, the AGILE MiniCALorimeter detected more than 2000 events in 8 years activity, by exploiting a unique sub-millisecond ...
    • Enhanced detection of terrestrial gamma-ray flashes by AGILE 

      Marisaldi, Martino; Argan, A; Ursi, Alessandro; Gjesteland, Thomas; Fuschino, F; Labanti, C; Galli, M; Tavani, M; Pittori, C; Verrecchia, F; D´Amico, F.; Østgaard, Nikolai; Mereghetti, S; Campana, R; Cattaneo, PW; Bulgarelli, S; Colafrancesco, S; Dietrich, S; Longo, F; Gianotti, F.; Giommi, P; Rappoldi, A; Trifoglio, M; Trois, A (Peer reviewed; Journal article, 2015-11-06)
      At the end of March 2015 the onboard software configuration of the Astrorivelatore Gamma a Immagini Leggero (AGILE) satellite was modified in order to disable the veto signal of the anticoincidence shield for the minicalorimeter ...
    • Gamma ray storms: preliminary meteorological analysis of AGILE TGFs: Meteorology of AGILE TGF observations 

      Tiberia, Alessandra; Dietrich, Stefano; Porcu, Federico; Marisaldi, Martino; Ursi, Alessandro; Tavani, Marco (Peer reviewed; Journal article, 2019)
      Despite the recognition from their discovery that terrestrial gamma ray flashes (TGFs) originate from thunderstorms, little is known about the TGF-producing storms. The characteristics of such thunderstorms are investigated ...
    • A New AGILE MCAL Configuration to Detect Gamma-Ray Bursts and Sub-threshold Events in the Multimessenger Era 

      Ursi, Alessandro; Tavani, Marco; Verrecchia, Francesco; Marisaldi, Martino; Argan, Andrea; Trois, Alessio; Tempesta, Patrizio (Peer reviewed; Journal article, 2019)
      Starting in 2016 August, the onboard software configuration of the Astrorivelatore Gamma ad Immagini LEggero (AGILE) MiniCALorimeter (MCAL) was modified in order to increase the instrument trigger capabilities for the ...
