Photodisintegration of Ultra-High-Energy Cosmic Rays revisited
E. Khan, S. Goriely, D. Allard +5
Recent microscopic and phenomenological calculations of giant dipole resonances for A <= 56 nuclei are presented. The derived photodisintegration cross sections are exhaustively co…
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…
