Journal ArticleDOI
The Hydrangea simulations: galaxy formation in and around massive clusters
Yannick M. Bahé,David J. Barnes,Claudio Dalla Vecchia,Claudio Dalla Vecchia,Scott T. Kay,Simon D. M. White,Ian G. McCarthy,Joop Schaye,Richard G. Bower,Robert A. Crain,Tom Theuns,Adrian Jenkins,Sean L. McGee,Matthieu Schaller,Peter A. Thomas,James W. Trayford +15 more
TL;DR: The Hydrangea simulations as mentioned in this paper are a suite of 24 cosmological hydrodynamic zoom-in simulations of massive galaxy clusters with baryon particle masses of ~10^6 M_Sun.
Journal ArticleDOI
The redshift evolution of massive galaxy clusters in the MACSIS simulations
TL;DR: The MAssive ClusterS and Intercluster Structures (MACSIS) project as discussed by the authors is a suite of 390 clusters simulated with baryonic physics that yields realistic massive galaxy clusters capable of matching a wide range of observed properties.
Journal ArticleDOI
The impact of baryons on massive galaxy clusters: halo structure and cluster mass estimates
TL;DR: In this paper, the BAHAMAS and MACSIS hydrodynamic simulations were used to quantify the impact of baryons on the mass distribution and dynamics of massive galaxy clusters, as well as the bias in X-ray and weak lensing mass estimates.
Journal ArticleDOI
The diverse density profiles of galaxy clusters with self-interacting dark matter plus baryons
Andrew Robertson,Richard Massey,Vincent R. Eke,Sean Tulin,Hai-Bo Yu,Yannick M. Bahé,Yannick M. Bahé,David J. Barnes,David J. Barnes,Richard G. Bower,Robert A. Crain,Claudio Dalla Vecchia,Claudio Dalla Vecchia,Scott T. Kay,Matthieu Schaller,Matthieu Schaller,Joop Schaye +16 more
TL;DR: In this article, the authors presented the first simulated galaxy clusters with both self-interacting dark matter (SIDM) and baryonic physics, which exhibited a greater diversity in both dark matter and stellar density profiles than their counterparts in simulations with collisionless dark matter.
Journal ArticleDOI

TL;DR: In this article, the authors explore the fraction of cool-core (CC) clusters in a large sample of $370$ clusters from IllustrisTNG, examining six common CC definitions.
