An updated list of AGILE bright gamma-ray sources and their variability in pointing mode
F. Verrecchia, C. Pittori, A. W. Chen +76
We present a variability study of a sample of bright gamma-ray (30 MeV -- 50 GeV) sources. This sample is an extension of the first AGILE catalogue of gamma-ray sources (1AGL), obt…
Calibration of AGILE-GRID with In-Flight Data and Monte Carlo Simulations
Andrew W. Chen, A. Argan, A. Bulgarelli +57
Context: AGILE is a gamma-ray astrophysics mission which has been in orbit since 23 April 2007 and continues to operate reliably. The gamma-ray detector, AGILE-GRID, has observed G…
A new modeling approach to the safety evaluation of N-modular redundant computer systems in presence of imperfect maintenance
Francesco Flammini, Stefano Marrone, Nicola Mazzocca +1
A large number of safety-critical control systems are based on N-modular redundant architectures, using majority voters on the outputs of independent computation units. In order to…
The Surprising Crab Nebula
E. Striani, M. Tavani, V. Vittorini
We will present our study of the flux and spectral variability of the Crab above 100 MeV on different timescales ranging from days to weeks. In addition to the four main intense an…
Transient Gamma-ray Emission from Cygnus X-3 Detected by AGILE: Leptonic and Hadronic Emission Models
G. Piano, M. Tavani, V. Vittorini +1
The AGILE satellite detected several episodes of transient gamma-ray emission from Cygnus X-3. Cross-correlating the AGILE light curve with both X-ray and radio monitoring data, we…
Variable gamma-ray emission from the Crab Nebula: short flares and long "waves"
E. Striani, M. Tavani, V. Vittorini +22
Gamma-ray emission from the Crab Nebula has been recently shown to be unsteady. In this paper, we study the flux and spectral variability of the Crab above 100 MeV on different tim…
