Long-lag GRBs have two different morphologies that can be delineated using the Internal Luminosity Function (ILF). Both burst types are typically dominated by a single broad pulse. Long-lag GRBs with large ILF indices are long FRED (Fast Rise Exponential Decay) bursts having well-defined peaks, while those with small ILF indices are long smooth bursts having no well-defined short timescale pulse structure. Long smooth bursts typically have have the longest lags of any type of GRB time history. We examine the hypothesis that long-lag GRBs are external shock signatures and contrast this with the hypothesis that they are merely broad internal shock pulses. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR] |
