Scientific paper

Analyses of time-resolved BATSE spectra, deconvolved using the Band GRB spectral function, reveal inconsistencies with the synchrotron shock model (SS-M) for gamma-ray bursts. However, we discover here that by instead deconvolving spectra using a smoothly-broken power law (SBPL) function, a vast majority of bursts are consistent with the SSM and do not violate the ``line of death.'' To resolve these discrepant conclusions, we compare both empirical functions to true synchrotron spectra and conclude that the Band GRB function is better suited for testing the SSM. This suggests that without some form of absorption, the SSM is still in conflict with observations. .
