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…
Modelling the Kinked Jet of the Crab Nebula
A. Mignone, E. Striani, M. Tavani +1
We investigate the dynamical propagation of the South-East jet from the Crab pulsar interacting with supernova ejecta by means of three-dimensional relativistic MHD numerical simul…
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…
Gamma-ray observations of Cygnus X-1 above 100 MeV in the hard and soft states
S. Sabatini, M. Tavani, P. Coppi +19
We present the results of multi-year gamma-ray observations by the AGILE satellite of the black hole binary system Cygnus X-1. In a previous investigation we focused on gamma-ray o…
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…
