nIFTy galaxy cluster simulations I: dark matter & non-radiative models
Federico Sembolini, Gustavo Yepes, Frazer R. Pearce +24
We have simulated the formation of a galaxy cluster in a CDM universe using twelve different codes modeling only gravity and non-radiative hydrodynamics (\art, \arepo, \hydra\ a…
The Influence of Mergers on Scatter and Evolution in Sunyaev-Zel'dovich Effect Scaling Relations
Liang Yu, Kaylea Nelson, Daisuke Nagai
The Sunyaev-Zel'dovich effect (SZE) observable-mass (Y-M) scaling relation is a promising technique for obtaining mass estimates for large samples of galaxy clusters and holds a ke…
Mass Accretion and its Effects on the Self-Similarity of Gas Profiles in the Outskirts of Galaxy Clusters
Erwin T. Lau, Daisuke Nagai, Camille Avestruz +2
Galaxy clusters exhibit remarkable self-similar behavior which allows us to establish simple scaling relationships between observable quantities and cluster masses, making galaxy c…
Non-Equilibrium Electrons in the Outskirts of Galaxy Clusters
Camille Avestruz, Daisuke Nagai, Erwin T. Lau +1
The analysis of X-ray and Sunyaev-Zeldovich measurements of the intracluster medium (ICM) assumes that electrons are in thermal equilibrium with ions in the plasma. However, electr…
Analytical model for non-thermal pressure in galaxy clusters - II. Comparison with cosmological hydrodynamics simulation
Xun Shi, Eiichiro Komatsu, Kaylea Nelson +1
Turbulent gas motion inside galaxy clusters provides a non-negligible non-thermal pressure support to the intracluster gas. If not corrected, it leads to a systematic bias in the e…
Temperature Structure of the Intra-Cluster Medium from SPH and AMR simulations
Elena Rasia, Erwin T. Lau, Stefano Borgani +8
Analyses of cosmological hydrodynamic simulations of galaxy clusters suggest that X-ray masses can be underestimated by 10% to 30%. The largest bias originates by both violation of…
