Mr Matteo Mergè (INFN)22/05/2013, 14:00for the PAMELA Collaboration. PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics) is a space-borne experiment launched on 15 June 2006 and continuously collecting data since then. The apparatus measures electrons, positrons, protons, anti-protons and heavier nuclei from about 100 MeV to several hundreds of GeV. On-board instrumentation is built around a...Go to contribution page

Matteo Martucci (LNF)22/05/2013, 14:15The satellite-borne PAMELA experiment has been continuously collecting data since 2006. This apparatus is designed to study charged particles in the cosmic radiation. The combination of permanent magnet, silicon strip spectrometer and silicon-tungsten imaging calorimeter, with the redundancy of instrumentation allows very precise studies on the physics of cosmic rays in a wide energy range...Go to contribution page

Dr Carlotta Pittori (INAF-OAR/ASDC)22/05/2013, 14:30AGILE is a Scientific Mission of the Italian Space Agency (ASI) with INFN, INAF e CIFS participation devoted to gamma-ray astrophysics. The satellite is in orbit since April 23rd, 2007. Thanks to its sky monitoring capability and fast ground segment alert system, AGILE is producing several important scientific results, among which the unexpected discovery of strong and rapid gamma-ray flares...Go to contribution page

Francesco Longo (TS)22/05/2013, 14:45In its almost 5 years mission, the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope has detected around 40 Gamma-Ray Bursts above 100 MeV. The high energy observations of Gamma-ray Bursts by Fermi-LAT gave rise to many recent theoretical challenges. The talk will present an overview of the general properties of GRBs in the high energy band and their theoretical implications.Go to contribution page

Dr Julien Bolmont (LPNHE Paris)22/05/2013, 15:00Because they are bright and distant, Gamma-ray Bursts (GRBs) have been used for more than a decade to test propagation of photons and to constrain relevant Quantum Gravity (QG) models in which the velocity of photons in vacuum can depend on their energy. With its unprecedented sensitivity and energy coverage, the Fermi satellite has provided the most constraining results on the QG energy scale...Go to contribution page

Mrs Martina Cardillo (INAF-IAPS & Università di Roma Tor Vergata)22/05/2013, 15:15The SNRW44 plays a crucial role in our understanding of the Cosmic Ray origin. Recently, AGILE and Fermi-LAT data have determined, for the first time in a supernova remnant, that the gamma-ray emission from W44 can be attributed to accelerated proton/ions. We present new W44 AGILE data and compare them with the recent Fermi data, in the light of new NANTEN2 telescope CO results. Our analysis...Go to contribution page

Dr Federico Fraschetti (University of Arizona)22/05/2013, 15:30Supernova Remnant (SNR) shocks are considered the main source of galactic cosmic-rays at least up to the knee of the cosmic-ray spectrum, and possibly further. From recent high-energy observations of SNRs a magnetic field at the shock far exceeding the theoretically predicted shock-compressed field has been inferred. Theoretical work in the last decade has linked particles accelerated at the...Go to contribution page

Dr Sara Buson (INFN & University of Padova)22/05/2013, 15:45During the last years our knowledge of Active Galactic Nuclei (AGNs) in the gamma-ray band has received a huge boost mainly due to the advent of a new generation of satellite instruments, such as the Fermi Large Area Telescope (LAT) and AGILE. Besides incrementing tremendously the number of gamma-ray detected objects and opening the window to the discovery of unexpected source classes, the new...Go to contribution page
