Dr Theodoros Geralis (NCSR Demokritos)12/03/2009 08:30Axions have been invented to accommodate the vanishingly small CP Violation in the strong interactions, probed mainly by the stringent limits on the neutron electric dipole moment. Additionally, their discovery may offer a solution to the so much wanted Cold Dark Matter constituent. CAST, the CERN Axion Solar Telescope, searched for axions with masses up to ~0.02eV and improved the axion to...Go to contribution page

Prof. nicola giglietto (dipartimento di fisica università e politecnico bari - infn bari)12/03/2009 08:50The Fermi Gamma-ray Space Telescope, formerly called GLAST, is a mission to measure the cosmic gamma-ray flux in the energy range 20 MeV to >300 GeV, with supporting measurements for gamma-ray bursts from 8 keV to 30 MeV. In addition to breakthrough capabilities in energy coverage and localization, the very large field of view enables observations of 20% of the sky at any instant, and the...Go to contribution page

Dr Martti Raidal (NICPB)12/03/2009 09:10The origin and the nature of Dark Matter cannot be addressed in the context of Standard Model. If the topology of the Universe is based on 2 flat +1 compact space dimension, constraints on the number of particles and on their quantum numbers occur from the requirement of gauge invariance in the 3-dimensional subspace. This scenario, called less-dimensions, suggests the GUT group of...Go to contribution page

Dr Lorenzo Perrone (Universita' del Salento and INFN Lecce)12/03/2009 09:30The Pierre Auger Cosmic Ray Observatory has been designed to investigate the origin and the nature of Ultra High Energy Cosmic Rays using a hybrid detection technique. It consists of a surface array overlooked by air fluorescence telescopes which together provide a powerful instrument for air shower reconstruction. The southern part of the Auger Observatory is taking data smoothly since...Go to contribution page

Michael Kachelriess (Department of Physics, NTNU)12/03/2009 09:55The Pierre Auger collaboration announced evidence for a correlation of the arrival directions of ultrahigh energy cosmic rays with active galactic nuclei. I discuss this analysis as well as possible tests with neutrino and gamma observations.Go to contribution page

Mlle Giada Carminati (University and INFN Bologna)12/03/2009 10:30The ANTARES (Astronomy with a Neutrino Telescope and Abyss enviromental RESearch) Collaboration constructed and deployed the world's largest operational underwater neutrino telescope, optimised for the detection of Cherenkov light produced by neutrino-induced muons. The detector has an effective area of the order of 0.1 square km and it is a first step towards a kilometric scale...Go to contribution page

Dr Carsten Rott (Ohio State University)12/03/2009 10:50Nearly a century after the discovery of cosmic rays their sources remain a mystery. The study of neutrinos along with other cosmic messengers is vital for ultimately identifying the sources of cosmic rays and understanding the nature of the underlying acceleration mechanisms. Neutrinos are especially important as they propagate nearly unperturbed through the universe and point back to their...Go to contribution page

Prof. Pierre Sokolsky (University of Utah)12/03/2009 11:10Final results on the cosmic ray spectrum, composition and anisotropy from the HiRes air-fluorescence experiment will be presented. Results on the ankle and GZK cutoff using both monocular and stereo data, cosmic ray composition using the Xmax method, and searches for correlation of the highest energy cosmic rays with putative sources such as AGN's an BL-Lacs will be given. A description of the...Go to contribution page
