Physics Results of the Pierre Auger Observatory

V. Van Elewyck

The Southern Pierre Auger Observatory is now nearing completion and the accumulating data sample has already allowed to extract scientific results of relevance for ultra-high energ…

Cosmogenic Neutrinos from the propagation of Ultra High Energy Nuclei

D. Allard, M. Ave, N. Busca +5

We calculate the flux of neutrinos generated by the propagation of ultra-high energy nuclei over cosmological distances. The propagation takes into account the interactions with co…

On the transition from Galactic to extragalactic cosmic-rays: spectral and composition features from two opposite scenarios

D. Allard, E. Parizot, A. V. Olinto

We study the phenomenology of cosmic-rays (CRs) at the galactic/extragalactic transition, focusing on two opposite models for the composition of the extragalactic (EG) component. M…

UHE nuclei propagation and the interpretation of the ankle in the cosmic-ray spectrum

D. Allard, E. Parizot, E. Khan +2

We consider the stochastic propagation of high-energy protons and nuclei in the cosmological microwave and infrared backgrounds, using revised photonuclear cross-sections and follo…

Generalised 3D-reconstruction method of a dipole anisotropy in cosmic-ray distributions

J. Aublin, E. Parizot

We develop a method to study the anisotropy of a cosmic-ray angular distribution, using both the right ascension and the declination of the arrival directions. It generalises the f…

GRBs and the 511 keV emission of the Galactic bulge

E. Parizot, M. Cassé, R. Lehoucq +1

We consider the phenomenology of the 511 keV emission in the Galactic bulge, as recently observed by INTEGRAL, and propose a model is which the positrons are produced by gamma-ray…

GZK horizon and magnetic fields

Etienne Parizot

We discuss some aspects of the propagation of high-energy cosmic rays (CRs) in turbulent magnetic fields, and propose a formula for the diffusion coefficient based on accurate simu…

Superbubbles and Energetic Particles in the Galaxy. I: Collective effects of particle acceleration

E. Parizot, A. Marcowith, E. van der Swaluw +2

Observations indicate that most massive stars in the Galaxy appear in groups, called OB associations, where their strong wind activity generates large structures known as superbubb…

The GZK cutoff behind a Magnetized Universe

Olivier Deligny, Antoine Letessier-Selvon, Etienne Parizot

We study the effect of random extra-galactic magnetic fields on the propagation of protons of energy larger than eV. We show that for reasonable field values (in the 100…

Multiple UHECR Events from Galactic hadron jets

E. Parizot

We propose a new observational test of top-down source models for the ultra-high-energy cosmic-rays (UHECRs), based on the simultaneous observation of two or more photons from the…

Photon Yields of Energetic Particles in the Interstellar Medium: an Easy Way to Calculate Gamma-ray Line Emission

E. Parizot, R. Lehoucq

A gamma-ray line production calculation in astrophysics depends on i) the composition and energy source spectrum of the energetic particles, ii) the propagation model, and iii) the…

Tests of Galactic Cosmic Ray Source Models

L O'C Drury, D C Ellison, F A Aharonian +9

This report discusses the possibilities for observational tests of current models and ideas regarding the origin of the Galactic Cosmic Rays using facilities which are already avai…

Background discrimination capabilities of a heat and ionization germanium cryogenic detector

P. Di Stefano, L. Berge, B. Chambon +26

The discrimination capabilities of a 70 g heat and ionization Ge bolometer are studied. This first prototype has been used by the EDELWEISS Dark Matter experiment, installed in the…
