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…

What's Missing in AGN Feedback? Lessons learnt from Magneticum, IllustrisTNG and Simba

D. T. Mazengo, P. Popesso, I. Marini +20

Accurately balancing gas reservoirs, star formation, and feedback across cosmic time remains a central challenge for galaxy formation models in modern hydrodynamical simulations. W…

Baryonic assembly bias in X-ray-selected galaxy groups and clusters: insights from the Magneticum simulation

Ilaria Marini, Tiago Castro, Paola Popesso +5

Galaxy groups and clusters trace the large-scale matter distribution, with their clustering usually interpreted mainly as a function of halo mass. Yet, at fixed mass, their baryoni…

Bulk and turbulent gas motions in the interacting galaxy cluster Abell 3395 South observed with XRISM

Naomi Ota, Angie Veronica, Jakob Dietl +8

We investigate the gas motions in the core region of the Abell~3395 South subcluster (A3395S) using high-resolution X-ray spectroscopy with XRISM/Resolve. By analyzing the Fe~XXV H…

Encyclopedia Magneticum: Scaling Relations from Cosmic Dawn to Present Day

Klaus Dolag, Rhea-Silvia Remus, Lucas M. Valenzuela +10

Galaxy and halo scaling relations, connecting a broad range of parameters, are well established from observations. The origin of many of these relations and their scatter is still…

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…
