Angle-Time-Energy Images of Ultra-High Energy Cosmic Ray Sources
Guenter Sigl
Substantial amount of information both on the source and on characteristics of intercepting magnetic fields is encoded in the distribution in arrival times, directions, and energie…
Reconstruction of Source and Cosmic Magnetic Field Characteristics from Clusters of Ultra-High Energy Cosmic Rays
Guenter Sigl, Martin Lemoine
We present a detailed Monte Carlo study coupled to a likelihood analysis of the potential of next generation ultra-high energy cosmic ray experiments to reconstruct properties of t…
Ultra-High Energy Neutrino-Nucleon Cross Section and Radiative Corrections
Guenter Sigl
A cubic kilometer scale experiment has been proposed to detect cosmic neutrinos of energy from tens of GeV up to the highest energies observed for cosmic rays, around 10**20 eV, or…
Maximum Likelihood Analysis of Clusters of Ultra-High Energy Cosmic Rays
Guenter Sigl, Martin Lemoine, Angela V. Olinto
We present a numerical code designed to conduct a likelihood analysis for clusters of nucleons above 10**19 eV originating from discrete astrophysical sources such as powerful radi…
Ultra-high energy cosmic ray sources and large scale magnetic fields
Martin Lemoine, Guenter Sigl, Angela V. Olinto +1
Protons of energies up to 10**20 eV can be subject to significant deflection and energy dependent time delay in lage scale extragalactic or halo magnetic fields of strengths compar…
Nucleon Spin Fluctuations and Neutrino-Nucleon Energy Transfer in Supernovae
Guenter Sigl
The formation of neutrino spectra in a supernova depends crucially on strength and inelasticity of weak interactions in hot nuclear matter. Neutrino interactions with nonrelativist…
