Magneto-Thermal Instability in Galaxy Clusters -- III. The Limit of Adiabatic Stratification
Lorenzo Maria Perrone, Henrik Latter
In the hot and dilute intracluster medium of galaxy clusters, large-scale buoyancy instabilities can develop due to the transport of heat along magnetic field lines. In particular,…
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…
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…
Thermal conductivity with bells and whistlers: suppression of the magnetothermal instability in galaxy clusters
Lorenzo Maria Perrone, Thomas Berlok, Christoph Pfrommer
In the hot intracluster medium (ICM) in galaxy clusters, plasma microinstabilities may play an important role in the transport of heat and momentum on the large scales. In this pap…
