Photometric Decomposition of Barred Galaxies
A. S. Reese, T. B. Williams, J. A. Sellwood +2
We present a non-parametric method for decomposition of the light of disk galaxies into disk, bulge and bar components. We have developed and tested the method on a sample of 68 di…
Milgrom Relation Models for Spiral Galaxies from Two-Dimensional Velocity Maps
Eric I. Barnes, Arthur Kosowsky, Jerry A. Sellwood
Using two-dimensional velocity maps and I-band photometry, we have created mass models of 40 spiral galaxies using the Milgrom relation (the basis of modified Newtonian dynamics, o…
Velocity Distributions from Nonextensive Thermodynamics
Eric I. Barnes, Liliya L. R. Williams, Arif Babul +1
There is no accepted mechanism that explains the equilibrium structures that form in collisionless cosmological N-body simulations. Recent work has identified nonextensive thermody…
Monte Carlo Simulations of Spin-Diffusion in a 2-D Heisenberg Paramagnet
R. Ragan, K. Grunwald, C. Glenz
We study spin diffusion and spin waves in paramagnetic quantum crystals (solid He-3, for example) by direct simulation of a square lattice of atoms interacting via a nearest-neighb…
