Magnetic fields in the weakly collisional plasma of galaxy clusters: from amplification mechanisms to observables

Yoan Rappaz

Magnetic fields are ubiquitous in the Universe and observed in various astrophysical systems, with different amplitudes. In galaxy clusters, they are typically on the order of a few

\mu\mathrm{G}

. Comparing this value with the amplitude of magnetic seed ...

The effect of pressure-anisotropy-driven kinetic instabilities on magnetic field amplification in galaxy clusters

Yoan Rappaz, Jennifer Waltraud Schober

Context. The intracluster medium (ICM) is the low-density diffuse gas that fills the space between galaxies within galaxy clusters. It is primarily composed of magnetized plasma, which reaches virial temperatures of up to 10(8) K, probably due to mergers o ...

Cosmic evolution of the Faraday rotation measure in the intracluster medium of galaxy clusters

Yoan Rappaz, Jennifer Waltraud Schober, Abhijit Bhausaheb Bendre

Context. Radio observations have revealed magnetic fields in the intracluster medium (ICM) of galaxy clusters, and their energy density is nearly in equipartition with the turbulent kinetic energy. This suggests magnetic field amplification by dynamo proce ...

Rotation measure and synchrotron emission signatures in simulations of magnetized galactic discs

Yoan Rappaz, Jennifer Waltraud Schober

We analyse observational signatures of magnetic fields for simulations of a Milky Way-like disc with supernova-driven interstellar turbulence and self-consistent chemical processes. In particular, we post-process two simulations data sets of the SILCC Proj ...

Assessment of bacterial and structural dynamics in aerobic granular sludge biofilms

Christof Holliger, David Gregory Weissbrodt, Yoan Rappaz

Aerobic granular sludge (AGS) is based on self-granulated flocs forming mobile biofilms with a gel-like consistence. Bacterial and structural dynamics from flocs to granules were followed in anaerobic-aerobic sequencing batch reactors (SBR) fed with synthe ...
