On the Detectability of Turbulence and Bulk Flows in X-ray Clusters
Rashid A. Sunyaev, Michael L. Norman, Greg L. Bryan
Cooling flows, cluster mergers and motions of galaxies through the cluster gas with supersonic and sonic velocities must lead to large scale motions of the intracluster medium (ICM…
On the Formation of Cool, Non-Flowing Cores in Galaxy Clusters via Hierarchical Mergers
J. O. Burns, P. M. Motl, M. L. Norman +1
We present a new model for the creation of cool cores in rich galaxy clusters within a LambdaCDM cosmological framework using the results from high spatial dynamic range, adaptive…
The Impact of Star Formation on Cool Core Galaxy Clusters
P. M. Motl, J. O. Burns, M. L. Norman +1
We present results from recent simulations of the formation and evolution of clusters of galaxies in a LambdaCDM cosmology. These simulations contain our most physically complete i…
On the Origin of Intracluster Entropy
G. Mark Voit, Michael L. Balogh, Richard G. Bower +2
The entropy distribution of the intracluster medium and the shape of its confining potential well completely determine the X-ray properties of a relaxed cluster of galaxies, motiva…
Temperature Bias in Measurements of The Hubble Constant Using The Sunyaev-Zeldovich Effect
Wen-Ching Lin, Michael L. Norman, Greg L. Bryan
Measurements of the Hubble constant to distant galaxy clusters using the Sunyaev-Zeldovich effect are systematically low in comparison to values obtained by other means. These meas…
Formation of Cool Cores in Galaxy Clusters via Hierarchical Mergers
Patrick M. Motl, Jack O. Burns, Chris Loken +2
We present a new scenario for the formation of cool cores in rich galaxy clusters based on results from recent high spatial dynamic range, adaptive mesh Eulerian hydrodynamic simul…
