6. Ultra-high energy cosmic ray theory faces observational puzzles.

Author

Olinto, Angela V.

Subjects
*COSMIC rays, *NUCLEAR energy, *ASTRONOMICAL observations, *DISTRIBUTION (Probability theory), *NUCLEAR models, *EXISTENCE theorems
Abstract

The origin of ultrahigh energy cosmic rays continues to challenge our imagination. Observations have answered previous open questions, such as the existence of a feature in the spectrum at the highest energies, but the arrival direction distribution and the composition indicators continue to challenge our models. I will briefly review these challenges. [ABSTRACT FROM AUTHOR]

7. From the galaxy to the edge of the universe: Plausible sources of UHECRs.

Author

Olinto, Angela V.

Subjects
*COSMIC rays, *NUCLEAR physics, *PARTICLES (Nuclear physics)
Abstract

The lack of a high energy cutoff in the cosmic ray spectrum together with an apparently isotropic distribution of arrival directions for the highest energy events have strongly constrained most models proposed for the generation of these particles. An overview of the theoretical proposals are presented along with their most general signatures. Future experimental tests of the different proposals are discussed. [ABSTRACT FROM AUTHOR]
