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…
Constraining Effective Viscosity in the Intracluster Medium via the Thermal Sunyaev-Zeldovich Effect -- Predictions from the SLOW Constrained Coma Cluster Simulations
Frederick Groth, Yuan Li, Joseph Golec +4
We study the effect of viscosity on the Sunyaev-Zeldovich signal in a simulated constrained Coma cluster analog. We aim to provide alternative constraints on the amount of viscosit…
Radio Halos in Galaxy Clusters as unveiled by the SKA telescope
R. Cassano, G. Di Gennaro, V. Cuciti +24
Giant radio halos (RHs) are diffuse, Mpc-scale synchrotron sources observed in a growing fraction of galaxy clusters. They trace relativistic particles and magnetic fields in the i…
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…
On the cosmology dependence of the cluster weak-lensing mass bias
S. Bocquet, A. Fumagalli, C. T. Davies +3
Measurements of the shear induced by weak gravitational lensing around galaxy cluster lines of sight are the gold standard for calibrating cluster observable-mass relations, thereb…
Built to Rest: The Evolving Star-Forming Main Sequence Requires Episodic Quiescence or Late Assembly
Lucas C. Kimmig, Jesse van de Sande, Rhea-Silvia Remus +3
The star-forming main sequence of galaxies has now been observed out to redshifts of and beyond. However, it remains unclear how long typical galaxies remain on or near it…
