THE DISTRIBUTION OF MATTER AROUND LUMINOUS GALAXIES (2008)
B. C. Bromley, R. Laflamme, M. S. Warren, W. H. Zurek
focus on an issue which was only lightly touched upon at the workshop but which ultimately may be important to our understanding of distribution of dark matter in the Universe.
Hypervelocity Stars: From the Galactic Center to the Halo (2008)
Kenyon, S. J., Bromley, B. C., Geller, M. J., Brown, W. R.
Hypervelocity stars (HVS) traverse the Galaxy from the central black hole to the outer halo. We show that the Galactic potential within 200 pc acts as a high pass filter preventing low velocity HVS...
Real-Space Cosmic Fields From Redshift-Space Distributions: A Green Function Approach (2007)
We present a new method for reconstructing the cosmological density, peculiar velocity and peculiar gravitational potential on large scales from redshift data. We remove the distorting effects of...
Finite-Size Gravitational Microlenses (2007)
Bromley Theoretical Astrophysics, B. C. Bromley
The finite size of a gravitational microlenses may have an effect on the observed the amplification of a background point source. The mechanism is occlusion of one or more of the source images by the...
Rich Cluster Simulation: Dynamics and Mass Estimates (2007)
Bromley Warren Zurek, B. C. Bromley, M. S. Warren, W. H. Zurek, P. J. Quinn
We present an analysis of a simulated rich cluster dominated by cold dark matter. Here we focus on the dynamics of collapsed dark matter halos within the cluster. We use projected positions and...
Enumeration of Trees by Vertex-Set Partitions (2007)
Generating functions are given for labeled tree enumeration by the number of edges with a specific color in a 2-color scheme, or equivalently, the number of vertex-set partitions. Two cases are...
Estimating Omega from Galaxy Redshifts: Linear Flow Distortions and Nonlinear Clustering (1997)
Bromley, B. C., Warren, M. S., Zurek, W. H.
We propose a method to determine the cosmic mass density Omega from redshift-space distortions induced by large-scale flows in the presence of nonlinear clustering. Nonlinear structures in redshift...
Quasirandom Number Generators for Parallel Monte Carlo Algorithms (1995)
A method for generating sequences of quasirandom numbers allows conventional serial Monte Carlo algorithms to be parallelized with no loss of computation efficiency. Specifically, a Sobol'...
The Second Coming of Cold Dark Matter? (1993)
Zurek Bromley Warren, S. Holt, W. H. Zurek, B. C. Bromley, M. S. Warren
While the standard cold dark matter (CDM) model has received numerous marks against it on the basis of a variety of observational data, the prediction of high oe v , the pairwise-velocity dispersion...
