This interdisciplinary group led by Tom Quinn includes faculty and students from the departments of Astronomy and Computer Science and Engineering at the University of Washington.

With support from the NSF, we also are collaborating with the Parallel Programming Laboratory at the University of Illinois at Urbana-Champaign on the development of Parallel tools for Cosmological N-body simulations

Analysis of simulations of comets in the Oort Cloud by Nathan Kaib and Tom Quinn have identified an overlooked mechanism for delivering comets into Earth crossing orbits. This puts tight constraints on the number of comets in the inner Oort cloud, and therefore the contribution of these comets to life threating impacts. See the UW Press Release.

Simulations of disk galaxies by Rok Roskar, Victor DeBattista and Tom Quinn show how stars like the Sun could migrate over great distances in the Milky Way. See the UW Press Release.

Announcing release 2.0 of ChaNGa, a massively parallel cosmological N-body code, developed in collaboration with the Parallel Programming Laboratory.
