The chemical evolution of galaxy clusters: Dissecting the iron mass budget of the intracluster medium [PDF]
Astronomy & Astrophysics, 2020 Aims. We study the chemical evolution of galaxy clusters by measuring the iron mass in the ICM after dissecting the abundance profiles into different components. Methods.

Turbulence decay in the density-stratified intracluster medium [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Turbulence evolution in a density-stratified medium differs from that of homogeneous isotropic turbulence described by the Kolmogorov picture. We evaluate the degree of this effect in the intracluster medium (ICM) with hydrodynamical simulations.

Electron Preacceleration in Weak Quasi-perpendicular Shocks in High-beta Intracluster Medium [PDF]
Astrophysical Journal, 2019 Giant radio relics in the outskirts of galaxy clusters are known to be lit up by the relativistic electrons produced via diffusive shock acceleration (DSA) in shocks with low sonic Mach numbers, Ms ≲ 3.

Witnessing the intracluster medium assembly at the cosmic noon in JKCS 041 [PDF]
Monthly notices of the Royal Astronomical Society, 2023 In this work we study the intracluster medium of a galaxy cluster at the cosmic noon: JKCS 041 at z = 1.803. A 28h long Sunyaev-Zel’dovich (SZ) observation using MUSTANG-2 allows us to detect JKCS 041 , even if intrinsically extremely faint compared to

A Heating Mechanism via Magnetic Pumping in the Intracluster Medium [PDF]
Astrophysical Journal, 2022 Turbulence driven by active galactic nuclei activity, cluster mergers, and galaxy motion constitutes an attractive energy source for heating the intracluster medium (ICM).

Life cycle of cosmic-ray electrons in the intracluster medium [PDF]
Astronomy & Astrophysics, 2022 We simulate the evolution of relativistic electrons injected into the medium of a small galaxy cluster by a central radio galaxy, studying how the initial jet power affects the dispersal and the emission properties of radio plasma.

Simulating the transport of relativistic electrons and magnetic fields injected by radio galaxies in the intracluster medium [PDF]
Astronomy & Astrophysics, 2021 Radio galaxies play an important role in the seeding of cosmic rays and magnetic fields in galaxy clusters. Here, we simulate the evolution of relativistic electrons injected into the intracluster medium by radio galaxies.

On the Small-scale Turbulent Dynamo in the Intracluster Medium: A Comparison to Dynamo Theory [PDF]
Astrophysical Journal, 2021 We present non-radiative, cosmological zoom-in simulations of galaxy-cluster formation with magnetic fields and (anisotropic) thermal conduction of one massive galaxy cluster with M vir ∼ 2 × 1015 M ⊙ at z ∼ 0.

Whistler-regulated Magnetohydrodynamics: Transport Equations for Electron Thermal Conduction in the High-β Intracluster Medium of Galaxy Clusters [PDF]
Astrophysical Journal, 2020 Transport equations for electron thermal energy in the high-β e intracluster medium (ICM) are developed that include scattering from both classical collisions and self-generated whistler waves. The calculation employs an expansion of the kinetic electron
