By tracking antiprotons out to a certain distance, then using their positions on the sky to determine the probability of UHECR coming from that direction before reinjecting them toward a detector, we can realistically simulate the effect the GMF would have on incoming UHECR particles' observed distributions at the Earth's surface.

This thesis contains work on the experimental study of ultra-high energy comic rays (UHECR). In Chapter 1, I give the general introduction to this subject, giving an outline both of the general study of cosmic rays, and of the work done in this thesis. In Chapter 2, I give the general history of the study of cosmic rays, including a discussion of possible methods of acceleration. In Chapter 3, I introduce the Pierre Auger Obvservatory (PAO), the data from which will be analyzed in this work. Chapters 4-5 cover the research done for my major work-submitted to Astroparticle Physics in June, 2007-as well as the modeling done for two talks given to the PAO during its semiannual meetings in March and November, 2006.
