Abstract
Gamma-ray burst (GRB) 130427A is one of the most energetic GRBs ever
observed. The initial pulse up to 2.5 s is possibly the
brightest
well-isolated pulse observed to date. A fine time resolution spectral
analysis shows
power-law decays of the peak energy from the onset of the
pulse, consistent with models of internal synchrotron shock pulses.
However, a strongly correlated power-law behavior is observed between
the luminosity and the spectral peak energy that is inconsistent with
curvature effects arising in the relativistic outflow. It is difficult
for any of the existing models to account for all of the observed
spectral and temporal behaviors simultaneously.
