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…
AGILE detection of Cygnus X-3 γ-ray active states during the period mid-2009/mid-2010
A. Bulgarelli, M. Tavani, A. W. Chen +70
Cygnus X-3 (Cyg X-3) is a well-known microquasar producing variable emission at all wavelengths. Cyg X-3 is a prominent X-ray binary producing relativistic jets, and studying its h…
Neutral pion emission from accelerated protons in the supernova remnant W44
A. Giuliani, M. Cardillo, M. Tavani +41
We present the AGILE gamma-ray observations in the energy range 50 MeV - 10 GeV of the supernova remnant (SNR) W44, one of the most interesting systems for studying cosmic-ray prod…
Discovery of Powerful Gamma-Ray Flares from the Crab Nebula
M. Tavani, A. Bulgarelli, V. Vittorini +65
The well known Crab Nebula is at the center of the SN1054 supernova remnant. It consists of a rotationally-powered pulsar interacting with a surrounding nebula through a relativist…
Direct Evidence for Hadronic Cosmic-Ray Acceleration in the Supernova Renmant IC 443
M. Tavani, A. Giuliani, A. W. Chen +59
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 gamma-ray emi…
Detection of Gamma-Ray Emission from the Vela Pulsar Wind Nebula with AGILE
A. Pellizzoni, A. Trois, M. Tavani +68
Pulsars are known to power winds of relativistic particles that can produce bright nebulae by interacting with the surrounding medium. These pulsar wind nebulae (PWNe) are observed…
Discovery of extreme particle acceleration in the microquasar Cygnus X-3
M. Tavani, A. Bulgarelli, G. Piano +67
The study of relativistic particle acceleration is a major topic of high-energy astrophysics. It is well known that massive black holes in active galaxies can release a substantial…
Agile Detection of Delayed Gamma-Ray Emission from the Short Gamma-Ray Burst GRB 090510
A. Giuliani, F. Fuschino, G. Vianello +59
Short gamma-ray bursts (GRBs), typically lasting less than 2 s, are a special class of GRBs of great interest. We report the detection by the AGILE satellite of the short GRB 09051…
First AGILE Catalog of High Confidence Gamma-Ray Sources
C. Pittori, F. Verrecchia, A. W. Chen +80
We present the first catalog of high-confidence gamma-ray sources detected by the AGILE satellite during observations performed from July 9, 2007 to June 30, 2008. Catalogued sourc…
