Gamma Rays and Neutrinos from a Powerful Cosmic Accelerator
Karl Mannheim
Recent measurements of gamma rays from the powerful quasar 3C273 by the Compton Gamma Ray Observatory show that a powerful cosmic accelerator must be operating. In this paper the e…

Extragalactic ultra high energy cosmic rays, II. Comparison with experimental data
Joerg P. Rachen, Todor Stanev, Peter L. Biermann
We compare the expected contribution of FR-II hot spots to the ultra-high energy cosmic ray spectrum (Rachen & Biermann 1993, A&A in press, BB paper astro-ph/9301010) to improved e…

Cosmic Rays I.: The cosmic ray spectrum between 10 TeV and 3 EeV
Peter L. Biermann
I develop a theory to account for the cosmic ray spectrum. The essential assumption is that, due to fast convective motions, the free mean path perpendicular to the magnetic field…
