72. Summary of low energy (E < 1 EeV) spectrum and composition

Andrea Chiavassa

11/10/2016, 16:10

I will present the more recent results obtained in the study of the cosmic ray spectrum and composition from 0.1 PeV to 1 EeV. Recent measurements of the primary spectrum show that, even above the knee, it cannot be described by a single power law. The measured structures have been detected by different experiments and the results agree inside the systematic error due to the energy...

67. The physics of ultra-high energy cosmic rays: spectra, composition and the transition between galactic and extra-galactic cosmic rays.

We will review the physics of ultra high energy cosmic rays discussing spectra and chemical composition. The expectations of different theoretical models will be compared with the latest experimental results. A particular emphasis will be given to the discussion of the transition between galactic and extra-galactic cosmic rays.

34. Anisotropy Search in Energy Distribution in the Northern Hemisphere Using the Telescope Array Surface Detector Data

The Telescope Array (TA) experiment is located in the western desert of Utah, USA, and observes ultra high energy cosmic rays in the northern hemisphere. In the region of highest energies, the shape of cosmic ray energy spectrum may contain information on the source density distribution and chemical composition. In this study, using observed events with the Telescope Array surface detector, we...

46. Lightest Nuclei UHECR from nearby galactic and nearest AGN sources

Prof. Daniele Fargion (Rome University 1 Sapienza and INFN)

11/10/2016, 17:45

The absence of UHECR clustering toward largest cluster of galaxy, Virgo, the presence of a smeared hot spot toward Cen A and M82, the presence of rarest nearest size multiplet along our galactic plane, all stand in favor of a very light UHECR composition. Their propagation from 20 Mpc Virgo is forbidden by photo-nuclear dissociation opacity, while it is allowed from few nearby AGN around 2-4...
