Dark Matter Signatures in the Anisotropic Radio Sky
Le Zhang, Guenter Sigl
We calculate intensity and angular power spectrum of the cosmological background of synchrotron emission from cold dark matter annihilations into electron positron pairs. We compar…

Lorentz Violation and Ultrahigh-Energy Photons
Matteo Galaverni, Guenter Sigl
The propagation of photons, electrons and positrons at ultra-high energies above 10^{19} eV can be changed considerably if the dispersion relations of these particles are modified…

Time Structure of Ultra-High Energy Cosmic Ray Sources and Consequences for Multi-messenger Signatures
Guenter Sigl
The latest results on the sky distribution of ultra-high energy cosmic ray sources have consequences for their nature and time structure. If the sources accelerate predominantly nu…
