“…The AGILE mission is an ASI (Italian Space Agency) space project dedicated to X and γ-ray astrophysics (Tavani et al 2009;Tavani 2019). The instrument consists of four different detectors onboard the satellite: an imaging γ-ray Silicon Tracker sensitive in the range 30 MeV -30 GeV (GRID; Barbiellini et al 2002), a coded mask X-ray imager sensitive in the 18-60 keV band (Super-AGILE; Feroci et al 2007), the Mini-Calorimeter sensitive in the 0.4-100 MeV band (MCAL; Labanti et al 2009) and the anti-coincidence (Perotti et al 2006) system.…”

FRB 180916 is a most intriguing source capable of producing repeating fast radio bursts with a periodic 16.3 day temporal pattern. The source is well positioned in a star forming region in the outskirts of a nearby galaxy at 150 Mpc distance. In this paper we report on the X-ray and γ-ray observations of FRB 180916 obtained by AGILE and Swift. We focused especially on the recurrent 5-day time intervals of enhanced radio bursting. In particular, we report on the results obtained in the time intervals Feb. 3 -8;Feb. 25; Mar. 5 -10; Mar. 22 -28, 2020 during a multiwavelength campaign involving high-energy and radio observations of FRB 180916. We also searched for temporal coincidences at millisecond timescales between the 32 known radio bursts of FRB 180916 and X-ray and MeV events detectable by AGILE. We do not detect any simultaneous event or any extended X-ray and γ-ray emission on timescales of hours/days/weeks.Our cumulative X-ray (0.3-10 keV) flux upper limit of 5 × 10 −14 erg cm −2 s −1 (obtained during 5-day active intervals from several 1-2 ks integrations) translates into an isotropic luminosity upper limit of L X,U L ∼ 1.5× 10 41 erg s −1 . Deep γ-ray observations above 100MeV over a many-year timescale provide an average luminosity upper limit one order of magnitude larger. These results provide the so-far most stringent upper limits on highenergy emission from the FRB 180916 source. Our results constrain the dissipation of

“…These events started the so-called "Multi-Messenger era" (MM) [9]. AGILE contributed to this new astronomy era [10] also thanks to its improved reaction capability to short timescale transients obtained with the real-time analysis (RTA) software developed in the context of MW and MM astronomy and described in this contribution.…”

In the multi-messenger era, space and ground-based observatories usually develop real-time analysis (RTA) pipelines to rapidly detect transient events and promptly share information with the scientific community to enable follow-up observations. These pipelines can also react to science alerts shared by other observatories through networks such as the Gamma-Ray Coordinates Network (GCN) and the Astronomer's Telegram (ATels). AGILE is a space mission launched in 2007 to study X-ray and gamma-ray phenomena. This contribution presents the technologies used to develop two types of AGILE pipelines using the RTApipe framework and an overview of the main scientific results. The first type performs automated analyses on new AGILE data to detect transient events and automatically sends AGILE notices to the GCN network. Since May 2019, this pipeline has sent more than 50 automated notices with a few minutes delay since data arrival. The second type of pipeline reacts to multi-messenger external alerts (neutrinos, gravitational waves, GRBs, and other transients) received through the GCN network and performs hundreds of analyses searching for counterparts in all AGILE instruments' data. The AGILE Team uses these pipelines to perform fast follow-up of science alerts reported by other facilities, which resulted in the publishing of several ATels and GCN circulars.

“…While it took EGRET one year and a half to release its first γ-ray all-sky map, Fermi -LAT maps the whole sky about every three hours since the beginning of the mission. Parallel to Fermi -LAT, the Astro-rivelatore Gamma a Immagini LEggero (AGILE ; Tavani et al, 2008), launched in 2007, has also contributed to a number of studies in γ-ray astronomy (see Tavani, 2019, for a review), although working with a smaller energy range and sensitivity than Fermi -LAT.…”
