Dianoga simulations of galaxy clusters and groups: Properties of the baryonic components
Stefano Borgani, Alice Damiano, Elena Rasia +12
We introduce the Dianoga set of cosmological simulations of galaxy clusters and groups, specifically aimed at studying the impact of the implementation of AGN feedback and star for…
Braginskii Viscosity in Cosmological Simulations of Galaxy Clusters: Implementation, Validation, and First Application
Tirso Marin-Gilabert, Ulrich P. Steinwandel, Milena Valentini +2
We present the implementation of an anisotropic viscosity solver within the magnetohydrodynamics (MHD) framework of the TreeSPH code OpenGadget3. The solver models anisotropic visc…
Turbulence in Simulated Local Cluster Analogs: One-to-one comparisons between SLOW and XRISM/Hitomi
Frederick Groth, Milena Valentini, Benjamin A. Seidel +4
The XRISM Resolve X-ray spectrometer allows to gain detailed insight into gas motions of the intra cluster medium (ICM) of galaxy clusters. Current simulation studies focus mainly…
Characterizing the roles of transitory obscured phases and inner torus in shaping the fractions of obscured AGN at cosmic noon
Alba V. Alonso-Tetilla, Francesco Shankar, Fabio Fontanot +11
The origin of obscuration in Active Galactic Nuclei (AGN) is still a matter of contention. It is unclear whether obscured AGN are primarily due to line-of-sight effects, a transito…
Hydrodynamic methods and sub-resolution models for cosmological simulations
Milena Valentini, Klaus Dolag
Cosmological simulations are powerful tools in the context of structure formation. They allow us to explore the assembly and clustering of dark matter halos, to validate or reject…
Turbulent Pressure Support in Galaxy Clusters -- Impact of the Hydrodynamical Solver
Frederick Groth, Milena Valentini, Ulrich P. Steinwandel +2
The amount of turbulent pressure in galaxy clusters is still debated, especially as for the impact of the dynamical state and the hydro-method used for simulations. We study the tu…
