The Center for Computational Astrophysics (CCA) is a research organization in Oak Park, Illinois, whose staff performs research into current areas of astronomy and applications of probability, statistics, and Monte Carlo simulations into other areas of inquiry. With a staff of retired professors from the Chicago area, CCA is the home base for the Near Earth Asteroid Reconnaissance Project, a world-wide network of amateur astronomers and small observatories involved in the discovery and determination of the orbits of near-earth asteroids, or more generally near-earth objects, with possible earth-crossing orbits. Its staff also authors textbooks in astronomy[1] and popularizes issues in astronomy with the media.[2]


CCA was founded in 1997 by its current director, astronomer Dr. Les Golden, a retired astronomy and physics professor at the University of Illinois at Chicago.[3]

Current Research

CCA coordinates the efforts of a world-wide network of volunteers and performs data reduction and orbital position determination for near-earth objects discovered by the Near Earth Asteroid Reconnaissance Project. Its associates have published papers in game theory,[4][5] internet traffic,[6], and random number generators.[7]
