Abstract
Light curves of the X-ray afterglow from 81 short gamma-ray bursts, from 2005 to 2018, were obtained from the Swift/XRT catalog. The light curves were fit with single power-law and double-power law models using the emcee library in Python and sorted into three groups: bursts well fit by a single power-law, bursts well fit by a double power-law, and bursts not well fit by either. Filters were applied to each category to identify bursts with a steep decay or a plateau. Once these unusual bursts were identified, their properties (duration, flux, fluence, and hardness) were compared to those of the more typical bursts. No significant trends were found to distinguish the unusual bursts from the rest.
