Gamma ray bursts can be used to discover the history of the universe back to the very first objects created after the Big Bang. The more we understand about the mechanism behind gamma ray bursts, the more we can exploit them to increase the precision of our knowledge of the universe's history. This poster presents an analysis of the lightcurve of GRB041223, as observed by the Burst Alert Telescope (BAT) on the Swift satellite. We performed a Fourier transform and a wavelet transform and verified that there is not short timescale (millisecond) structure in the burst. This result is consistent with current models for the geometry of the energy shells emitted from a gamma-ray burst.
