Magnetic fields in the Large-Scale Structure of the Universe
Dongsu Ryu, Dominik R. G. Schleicher, Rudolf A. Treumann +2
Magnetic fields appear to be ubiquitous in astrophysical environments. Their existence in the intracluster medium is established through observations of synchrotron emission and Fa…
The First Magnetic Fields
Lawrence M. Widrow, Dongsu Ryu, Dominik Schleicher +3
We review current ideas on the origin of galactic and extragalactic magnetic fields. We begin by summarizing observations of magnetic fields at cosmological redshifts and on cosmol…
MHD Turbulence Simulation in a Cosmic Structure Context
T. W. Jones, D. H. Porter, D. Ryu +1
The gaseous media of galaxy clusters and cosmic filaments, which constitute most of the baryonic matter in the universe, is highly dynamic. It is also probably turbulent, although…
Faraday Rotation Measure due to the Intergalactic Magnetic Field II: the Cosmological Contribution
Takuya Akahori, Dongsu Ryu
We investigate the Faraday rotation measure (RM) due to the intergalactic magnetic field (IGMF) through the cosmic web up to cosmological distances, using a model IGMF based on tur…
A Comparison of Cosmological Codes: Properties of Thermal Gas and Shock Waves in Large Scale Structures
F. Vazza, K. Dolag, D. Ryu +4
[...] We present results for the statistics of thermal gas and the shock wave properties for a large volume simulated with three different cosmological numerical codes: the Euleria…
Re-acceleration of Nonthermal Particles at Weak Cosmological Shock Waves
Hyesung Kang, Dongsu Ryu
We examine diffusive shock acceleration (DSA) of the pre-exisiting as well as freshly injected populations of nonthermal, cosmic-ray (CR) particles at weak cosmological shocks. Ass…
Cluster Turbulence: Simulation Insights
T. W. Jones, David H. Porter, Dongsu Ryu +1
Cluster media are dynamical, not static; observational evidence suggests they are turbulent. High-resolution simulations of the intracluster media (ICMs) and of idealized, similar…
