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…
Identifying heating processes in simulations with an entropy-based scheme: A single jet episode in a galaxy cluster
Moun Meenakshi, Rainer Weinberger, Christoph Pfrommer +1
Understanding heating processes in galaxy clusters is essential for predicting the regulation of radiative cooling and star formation, and for clarifying the mechanisms underlying…
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…
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…
Does the magneto-thermal instability survive whistler-suppression of thermal conductivity in galaxy clusters?
Lorenzo Maria Perrone, Thomas Berlok, Christoph Pfrommer
The hot and dilute intracluster medium (ICM) plays a central role in many key processes that shape galaxy clusters.Nevertheless, the nature of plasma turbulence and particle transp…
