The relation of extragalactic cosmic ray and neutrino fluxes: the logic of the upper bound debate
Jorg P. Rachen, R. J. Protheroe, Karl Mannheim
In a recent paper, Waxman and Bahcall (PRD 59, 023002) claimed that the present data on ultra-high energy cosmic rays imply a model-independent upper bound on extragalactic neutrin…

The origin of soft X-rays in luminous AGN
K. Mannheim, M. Schulte, J. Rachen
We predict that the UV bump spectrum of quasars extends into the soft X-ray range with a steep power law. For radio-louds, the spectral index is alpha_s ~ 1.7 (S_nu = S_o nu^-alpha…
