The PICO-Cluster Project: presenting the galaxy cluster sample and studying magnetic field growth, Faraday rotation and Braginskii heating
Thomas Berlok, Christoph Pfrommer, Ewald Puchwein +9
Galaxy clusters constitute a microcosm of the Universe and offer a unique laboratory for studying plasma astrophysics, encompassing processes such as cosmic-ray acceleration and no…
Active galactic nucleus driven jet feedback in cosmologically forming cool-core galaxy clusters I: The effect of hierarchical assembly on intra-cluster medium properties
Rainer Weinberger, Lorenzo Maria Perrone, Christoph Pfrommer +7
The atmospheres of cool-core galaxy clusters are excellent probes of astrophysical plasmas. However, how the interplay between assembly and active galactic nucleus (AGN) feedback l…
Characterizing turbulence in galaxy clusters: Defining turbulent energies and assessing multi-scale versus fixed-scale filters
Lorenzo Maria Perrone, Thomas Berlok, Ewald Puchwein +1
Disentangling turbulence and bulk motions in the intracluster medium (ICM) of galaxy clusters is inherently ambiguous, as the plasma is continuously stirred by different processes…
Magnetic dynamos in galaxy clusters: the crucial role of galaxy formation physics at high redshifts
Larissa Tevlin, Thomas Berlok, Christoph Pfrommer +6
Observations of Faraday rotation and synchrotron emission in galaxy clusters imply large-scale magnetic fields with strengths possibly extending back to . Non-ra…
Anisotropic Velocity Fluctuations in Galaxy Mergers: A Probe of the Magnetic Field
Yue Hu, Joseph Whittingham, A. Lazarian +3
Magnetic fields and turbulence are fundamental to the evolution of galaxies, yet their precise measurement and analysis present significant challenges. The recently developed Veloc…
The in situ formation of molecular and warm ionised gas triggered by hot outflows
Philipp Girichidis, Thorsten Naab, Stefanie Walch +1
Molecular outflows contributing to the matter cycle of star forming galaxies are now observed in small and large systems at low and high redshift. Their physical origin is still un…
Braginskii viscosity on an unstructured, moving mesh accelerated with super-time-stepping
Thomas Berlok, Ruediger Pakmor, Christoph Pfrommer
We present a method for efficiently modelling Braginskii viscosity on an unstructured, moving mesh. Braginskii viscosity, i.e., anisotropic transport of momentum with respect to th…
The impact of magnetic fields on cold streams feeding galaxies
Thomas Berlok, Christoph Pfrommer
High redshift, massive halos are observed to have sustained, high star formation rates, which require that the amount of cold gas in the halo is continuously replenished. The cooli…
On the Kelvin-Helmholtz instability with smooth initial conditions -- Linear theory and simulations
Thomas Berlok, Christoph Pfrommer
The Kelvin-Helmholtz instability (KHI) is a standard test of hydrodynamic and magnetohydrodynamic (MHD) simulation codes and finds many applications in astrophysics. The classic li…
