Ultrahigh Energy Nuclei Propagation in a Structured, Magnetized Universe
Eric Armengaud, Guenter Sigl, Francesco Miniati
We compare the propagation of iron and proton nuclei above 10^19 eV in a structured Universe with source and magnetic field distributions obtained from a large scale structure simu…
Cosmic Magnetic Fields and Their Influence on Ultra-High Energy Cosmic Ray Propagation
Guenter Sigl, Francesco Miniati, Torsten Ensslin
We discuss the influence of large scale cosmic magnetic fields on the propagation of hadronic cosmic rays above 10^19 eV based on large scale structure simulations. Our simulations…
Lectures on Astroparticle Physics
Guenter Sigl
These are extended notes of a series of lectures given at the XIth Brazilian School of Cosmology and Gravitation. They provide a selection of topics at the intersection of particle…
Ultra-High Energy Cosmic Ray Nuclei from Individual Magnetized Sources
Guenter Sigl
We investigate the dependence of composition, spectrum and angular distributions of ultra-high energy cosmic rays above 10^19 eV from individual sources on their magnetization. We…
Some Current Theoretical Issues around Ultra-High Energy Cosmic Rays
Guenter Sigl
We address some current theoretical issues around ultra-high energy cosmic rays. We recall that scenarios producing more gamma-rays than cosmic rays up to high redshift can in gene…
Ultra-High Energy Cosmic Ray Probes of Large Scale Structure and Magnetic Fields
Guenter Sigl, Francesco Miniati, Torsten Ensslin
We study signatures of a structured universe in the multi-pole moments, auto-correlation function, and cluster statistics of ultra-high energy cosmic rays above 10^19 eV. We compar…
