Propagation of high-energy cosmic rays in extragalactic turbulent magnetic fields: resulting energy spectrum and composition

, 2007
15 pages, 20 figuresWe extend previous studies of mixed-composition extragalactic cosmic-ray source models, by investigating the influence of a non-negligible extragalactic magnetic field on the propagated cosmic-ray spectrum and composition.

Cio-cio-san no Yūutsu: memoirs of magnetogenesis and Turbulent Dynamo Theory

, 2013
The origins of cosmic magnetic fields are not as yet well understood. In this dissertation we investigate, via direct numerical simulation, the temporal evolution and behaviour of magnetic fields that are generated from absolute zero initial conditions ...

Propagation of ultrahigh energy cosmic rays in extragalactic magnetic fields: a view from cosmological simulations

, 2016
We use the crpropa code to simulate the propagation of ultrahigh energy cosmic rays (with energy â¥1018eV and pure proton composition) through extragalactic magnetic fields that have been simulated with the cosmological enzo code.

Using rotation measure grids to detect cosmological magnetic fields: A Bayesian approach [PDF]

, 2016
Determining magnetic field properties in different environments of the cosmic large-scale structure as well as their evolution over redshift is a fundamental step toward uncovering the origin of cosmic magnetic fields. Radio observations permit the study

Estimating extragalactic Faraday rotation [PDF]

, 2015
Observations of Faraday rotation for extragalactic sources probe magnetic fields both inside and outside the Milky Way. Building on our earlier estimate of the Galactic contribution, we set out to estimate the extragalactic contributions.

Mapping deflections of Ultra-High Energy Cosmic Rays in Constrained Simulations of Extragalactic Magnetic Fields

, 2003
We construct the first realistic map of deflections of ultra-high energy cosmic rays by extragalactic magnetic fields, using a magneto-hydrodynamical simulation of cosmic structure formation that reproduces the positions of known galaxy clusters in the ...

Rayos cósmicos ultra-energéticos y lentes magnéticas

Momento, 2000
I discuss the effects associated to the defiection of ultra- high energy cosmic rays by galactic magnetic fields. These are of particular interest for the study and localization of extragalactic sources, which is one of the primary objectives of the ...
