The IBIS telescope is the high angular resolution gamma-ray imager on-board INTEGRAL Observatory, successfully launched from Baikonur (Kazakhstan) 17th of October 2002. This medium size ESA project, planned for a 2 year mission with possible extension to 5, devoted observation sky in energy range 3 keV 10 MeV (Winkler [CITE]). imaging system based on two independent solid state detector arrays optimised low ( keV) and MeV) energies surrounded by an active VETO System. efficiency shield...
<i>Context. <i/> AGILE is an Italian Space Agency mission dedicated to observing the gamma-ray Universe. The AGILE's very innovative instrumentation for first time combines a imager (sensitive in energy range 30 MeV–50 GeV), hard X-ray 18–60 keV), calorimeter 350 keV–100 MeV), and anticoincidence system. was successfully launched on 2007 April 23 from Indian base of Sriharikota inserted equatorial orbit with low particle background.<i>Aims. <i/>AGILE provides crucial data study active...
The well known Crab Nebula is at the center of SN1054 supernova remnant. It consists a rotationally-powered pulsar interacting with surrounding nebula through relativistic particle wind. emissions originating from and have been considered to be essentially stable. Here we report detection strong gamma-ray (100 MeV-10 GeV) flares observed by AGILE satellite in September, 2010 October, 2007. In both cases, unpulsed flux increased factor 3 compared non-flaring flux. flare luminosity short...
We report the detection by Astrorivelatore Gamma a Immagini Leggero (AGILE) satellite of terrestrial gamma ray flashes (TGFs) obtained with minicalorimeter (MCAL) detector operating in energy range 0.3–100 MeV. select events typically lasting few milliseconds spectral and directional selections consistent TGF characteristics previously reported other space missions. During period 1 June 2008 to 31 March 2009 we detect 34 high‐confidence showing millisecond durations geographical distribution...
Strong electric discharges associated with thunderstorms can produce terrestrial gamma-ray flashes (TGFs), i.e., intense bursts of x rays and $\ensuremath{\gamma}$ lasting a few milliseconds or less. We present in this Letter new TGF timing spectral data based on the observations Italian Space Agency AGILE satellite. determine that emission above 10 MeV has significant power-law component reaching energies up to 100 MeV. These results challenge theoretical models runaway electron...
eXTP is a science mission designed to study the state of matter under extreme conditions density, gravity and magnetism. Primary goals are determination equation at supra-nuclear measurement QED effects in highly magnetized star, accretion strong-field regime gravity. targets include isolated binary neutron stars, strong magnetic field systems like magnetars, stellar-mass supermassive black holes. The carries unique unprecedented suite state-of-the-art scientific instruments enabling for...
THESEUS, one of the two space mission concepts being studied by ESA as candidates for next M5 within its Comsic Vision programme, aims at fully exploiting Gamma-Ray Bursts (GRB) to solve key questions about early Universe, well becoming a cornerstone multi-messenger and time-domain astrophysics. By investigating first billion years Universe through high-redshift GRBs, THESEUS will shed light on main open issues in modern cosmology, such population primordial low mass luminosity galaxies,...
The Supernova Remnant (SNR) IC 443 is an intermediate-age remnant well known for its radio, optical, X-ray and gamma-ray energy emissions. In this Letter we study the emission above 100 MeV from as obtained by AGILE satellite. A distinct pattern of diffuse in range MeV-3 GeV detected across SNR with prominent maximum (source "A") localized Northeastern shell a flux F = (47 \pm 10) 10^{-8} photons cm^{-2} s^{-1} MeV.

We present the first catalog of high-confidence <i>γ<i/>-ray sources detected by AGILE satellite during observations performed from July 9, 2007 to June 30, 2008. Cataloged were merging all available data over entire time period. AGILE, launched in April 2007, is an ASI mission devoted 30 MeV–50 GeV energy range, with simultaneous X-ray imaging capability 18–60 keV band. This based on Gamma-Ray Imaging Detector (GRID) for energies greater than 100 MeV. For catalog, we adopted a conservative...
