The rise and fall of top-down models as main UHECR sources
M. Kachelriess
The motivation and the current status of top-down models as sources of ultrahigh energy cosmic rays (UHECR) are reviewed. Stimulated by the AGASA excess, they were proposed as the…
A global autocorrelation study after the first Auger data: impact on the number density of UHECR sources
A. Cuoco, S. Hannestad, T. Haugboelle +2
We perform an autocorrelation study of the Auger data with the aim to constrain the number density n_s of ultrahigh energy cosmic ray (UHECR) sources, estimating at the same time t…
High energy radiation from Centaurus A
M. Kachelriess, S. Ostapchenko, R. Tomas
We calculate for the nearest active galactic nucleus (AGN), Centaurus A, the flux of high energy cosmic rays and of accompanying secondary photons and neutrinos expected from hadro…
The GZK horizon and constraints on the cosmic ray source spectrum from observations in the GZK regime
M. Kachelriess, E. Parizot, D. V. Semikoz
We discuss the GZK horizon of protons and present a method to constrain the injection spectrum of ultrahigh energy cosmic rays (UHECRs) from supposedly identified extragalactic sou…
High energy neutrino yields from astrophysical sources II: Magnetized sources
M. Kachelriess, S. Ostapchenko, R. Tomas
We calculate the yield of high energy neutrinos produced in astrophysical sources for arbitrary interaction depths and magnetic field strengths . We take into account ener…
Second dip as a signature of ultrahigh energy proton interactions with cosmic microwave background radiation
V. Berezinsky, A. Gazizov, M. Kachelrieß
We discuss as a new signature for the interaction of extragalactic ultrahigh energy protons with cosmic microwave background radiation a spectral feature located at $E=6.3\times 10…
