Constraining dark halos with tidal tails
John Dubinski, Chris Mihos, Lars Hernquist
Massive and extended dark halos can inhibit the formation of long tidal tails in galaxy collisions. We examine this effect using an extensive survey of simulations with different d…
Searching for Machos (and other Dark Matter Candidates) in a Simulated Galaxy
Lawrence M. Widrow, John Dubinski
We conduct gravitational microlensing experiments in a galaxy taken from a cosmological N-body simulation. Hypothetical observers measure the optical depth and event rate toward hy…
The Origin of the Brightest Cluster Galaxies
John Dubinski
Most clusters and groups of galaxies contain a giant elliptical galaxy in their centres which far outshines and outweighs normal ellipticals. The origin of these brightest cluster…
Tidal Tales Two: The Effect of Dark Matter Halos on Tidal Tail Morphology and Kinematics
Chris Mihos, John Dubinski, Lars Hernquist
We examine the effect of different dark matter halo potentials on the morphology and kinematics of tidals tails in a merger model of NGC 7252. We find that models of merging galaxi…
Parallel TreeSPH
Romeel Dave', John Dubinski, Lars Hernquist
We describe PTreeSPH, a gravity treecode combined with an SPH hydrodynamics code designed for massively parallel supercomputers having distributed memory. Our computational algorit…
