The Effect of the Interstellar Model on Star Formation Properties in Galactic Disks
Elizabeth J. Tasker, Greg L. Bryan
We studied the effect of interstellar gas conditions on global galaxy simulations by considering three different models for the ISM. Our first model included only radiative cooling…
Environmentally-Driven Evolution of Simulated Cluster Galaxies
Stephanie Tonnesen, Greg L. Bryan, J. H. van Gorkom
Galaxies in clusters are gas-deficient and a number of possible explanations for this observation have been advanced, including galaxy-cluster tidal interactions, galaxy harassment…
The role of the Interstellar Medium in Galaxy Formation Simulations
Greg L. Bryan
There is a strong connection between the formation of a disk galaxy and the properties of the interstellar medium (ISM). Theoretical work has typically either focused on the cosmol…
Radial Alignment in Simulated Clusters
Maria J. Pereira, Greg L. Bryan, Stuart P. D. Gill
Observational evidence for the radial alignment of satellites with their dark matter host has been accumulating steadily in the past few years. The effect is seen over a wide range…
Cosmological Simulations of the Preheating Scenario for Galaxy Cluster Formation: Comparison to Analytic Models and Observations
Joshua D. Younger, Greg L. Bryan
We perform a set of non--radiative cosmological simulations of a preheated intracluster medium in which the entropy of the gas was uniformly boosted at high redshift. The results o…
Simulating Cosmological Evolution with Enzo
Michael L. Norman, Greg L. Bryan, Robert Harkness +4
In this paper we describe our massively parallel version of Enzo, a multiphysics, parallel, AMR application for simulating cosmological structure formation developed at UCSD and Co…
