There is strong evidence that galaxies such as our own are embedded in
massive halos of non-luminous dark matter. Morever, cosmological
constraints indicate that most, if not all, of this dark matter is in
the form some exotic non-baryonic particle and numerous groups around
the world have set out to detect these particles as they pass through
Much of my research focuses on the nature of dark matter halos. What
are their shapes? Is dark matter smoothly distributed or clumpy? What
effect do dark halos have on galactic dynamics?
Over the past few years, I have worked with John Dubinski at the University
of Toronto to refine and expand a code, dubbed GalactICS, which builds
equilibrium models for dist galaxies. These models have been used extensively
in simulations of galactic dynamics. Studies range from simulations
of bar formation to galactic mergers.
I am currently involved in the Pan-Andromeda Archeological Survey (PAndAS),
an international collaboration whose aim is to explore the environment
of the Andromeda and Triangulum galaxies.
