An Atlas of Gas Motions in the TNG-Cluster Simulation: from Cluster Cores to the Outskirts
Mohammadreza Ayromlou, Dylan Nelson, Annalisa Pillepich +6
Galaxy clusters are unique laboratories for studying astrophysical processes and their impact on gas kinematics. Despite their importance, the full complexity of gas motion within…
The heart of galaxy clusters: demographics and physical properties of cool-core and non-cool-core halos in the TNG-Cluster simulation
Katrin Lehle, Dylan Nelson, Annalisa Pillepich +2
We analyze the physical properties of the gaseous intracluster medium (ICM) at the center of massive galaxy clusters with TNG-Cluster, a new cosmological magnetohydrodynamical simu…
The physical origins of gas in the circumgalactic medium using observationally-motivated TNG50 mocks
Simon Weng, Celine Peroux, Rahul Ramesh +5
Absorbers in the spectrum of background objects probe the circumgalactic medium (CGM) surrounding galaxies, but its physical properties remain unconstrained. We use the cosmologica…
Radio relics in massive galaxy cluster mergers in the TNG-Cluster simulation
W. Lee, A. Pillepich, J. ZuHone +4
Radio relics are diffuse synchrotron sources in the outskirts of merging galaxy clusters energized by the merger shocks. In this paper, we present an overview of the radio relics i…
Introducing the TNG-Cluster Simulation: overview and physical properties of the gaseous intracluster medium
Dylan Nelson, Annalisa Pillepich, Mohammadreza Ayromlou +4
We introduce the new TNG-Cluster project, an addition to the IllustrisTNG suite of cosmological magnetohydrodynamical simulations of galaxy formation. Our objective is to significa…
The hot circumgalactic media of massive cluster satellites in the TNG-Cluster simulation: existence and detectability
Eric Rohr, Annalisa Pillepich, Dylan Nelson +2
The most massive galaxy clusters in the Universe host hundreds of massive satellite galaxies~$\mstar\sim10^{10-12.5} msun$, but it is unclear if these satellites are able to retain…
