135. Measurement of the all-particle and light-component cosmic ray energy spectra with ARGO-YBJ

Ivan De Mitri (LE)

10/1/14, 4:30 PM

oral

Cosmic ray physics in the 1TeV-10PeV primary energy range is among the main scientific goals of the ARGO-YBJ experiment. The detector, located in the Cosmic Ray Observatory of Yangbajing (Tibet, China) at 4300m a.s.l., is a full coverage Extensive Air Shower array, consisting of a carpet of Resistive Plate Chambers (RPC) of about 7000m2. The apparatus layout, performance and location oer a...

113. The Cosmic Ray light component spectrum in the 10-1000 TeV energy range measured by the ARGO-YBJ experiment by using a bayesian approach

Paolo Montini (ROMA3)

10/1/14, 5:00 PM

oral

The ARGO-YBJ experiment is a full coverage air shower detector operated at the Yangbajing international cosmic ray observatory. The detector has been in stable data taking in its full configuration since November 2007 to February 2013. The high altitude and the high segmentation and spacetime resolution offer the possibility to explore the cosmic ray energy spectrum in a very wide range, from...

123. Tunka-133: Results of 5 Years Observation and Future Experiments

Prof. Vasily Prosin (Skobeltsyn Institute of Nuclear Physics of Lomonosov Moscow State University)

10/1/14, 5:20 PM

oral

EAS Cherenkov light array Tunka-133 with ~3 km2 geometric area operated since 2009. Five winter seasons of data acquisition (~107 triggers) and high quality of information permitted us to reconstruct primary energy spectrum and mass composition in the energy range 6•1015 to 1018 eV. This energy range is the most important for understanding of transition from Galactic to extragalactic CR. The...

164. Correlating the Hot Spot in UHECR rays with its possible source

Prof. Daniele Fargion (INFN and Dipt Fisica Sapienza)

10/1/14, 5:50 PM

UHECR (Ultra High Energy Cosmic Rays) are reaching a large sample of events both in the South (by AUGER) and recently also in the North terrestrial emisphere (by TA, Terrestrial Array Telescope). The latter events are showing an apparent wide Hot Spot clustering toward an unexpected area of the sky. Some tentative correlation with Ursa Major Cluster has been offered: however the remarkable...
