Extragalactic cosmic-ray source composition and the interpretation of the ankle
D. Allard, E. Parizot, A. V. Olinto +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…
Indirect manifestation of GRBs in the Galaxy: Compton trails and positrons
Etienne Parizot
Two independent indirect manifestations of Galactic gamma-ray bursts (GRBs) are considered, whose importance for gamma-ray astronomy will depend on a still poorly known -- though a…
Cosmic-rays: an unsolved mystery at all energies!
E. Parizot
We consider the phenomenology of cosmic-rays (CRs) and stress the interest of jointly studying their properties over the whole energy spectrum. While UHECRs are known to raise impo…
Superbubbles and the Galactic evolution of Li, Be and B
Etienne Parizot
From a recent re-analysis of the available data, Be and B Galactic evolution appears to show evidence for a two-slope behaviour with respect to O. The inferred Be/O abundance ratio…
Bimodal production of Be and B in the early Galaxy
E. Parizot, L. Drury
Recently models based on the acceleration of metal-rich material inside superbubbles have been proposed to account for the observed abundances of Be and B in metal-poor halo stars.…
The superbubble model for Li, Be and B production and Galactic evolution
Etienne Parizot, Luke Drury
We show that the available constraints relating to LiBeB Galactic evolution can be accounted for by the so-called superbubble model, according to which particles are efficien…
