High Performance Commodity Networking in a 512-CPU Teraflop Beowulf Cluster for Computational Astrophysics
John Dubinski, Robin Humble, Ue-Li Pen +2
We describe a new 512-CPU Beowulf cluster with Teraflop performance dedicated to problems in computational astrophysics. The cluster incorporates a cubic network topology based on…
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…
A Universal Temperature Profile for Galaxy Clusters
C. Loken, M. L. Norman, E. Nelson +3
We investigate the predicted present-day temperature profiles of the hot, X-ray emitting gas in galaxy clusters for two cosmological models - a current best-guess LCDM model and st…
Do Cluster Cooling Flows Survive Head-on Galaxy Cluster Mergers?
P. L. Gomez, C. Loken, K. Roettiger +1
We report the results of recent numerical simulations of the head-on merger of a cooling flow cluster with an infalling subcluster of galaxies. These simulations examined the effec…
Simulated Cluster Archive: A Computational Catalog of X-Ray Clusters in a Lambda-CDM Universe
Michael L. Norman, Greg Daues, Erik Nelson +4
We have simulated the evolution of a large sample of X-ray clusters in a Lambda-CDM universe at high spatial resolution using adaptive mesh refinement and placed the results in an…
The Effect of the Cosmic Web on Cluster Weak Lensing Mass Estimates
Christopher A. Metzler, Martin White, Chris Loken
In modern hierarchical theories of structure formation, rich clusters of galaxies form at the vertices of a weblike distribution of matter, with filaments emanating from them to la…
