Scientific paper

We present a systematic survey of the temporal and spectral properties of all GRB X-ray afterglows observed by Swift-XRT between January 2005 and July 2007. We have constructed a catalog of all light curves and spectra, and classify them in the context of the canonical model with some modifications. By fitting many variations of the closure relations, we explore the global models that can characterize each afterglow and the statistical frequency of these models. These variations include different mediums, changing micro-physical parameters, addition of energy injection and several jet models. With this data set, we identify canonical, previously ambiguous, and non-typical jet break candidates. These additional jet breaks help to explain some of the "missing" X-ray jet breaks in the Swift era. We use these jet breaks to put constraints on energetics and jet geometry.
