Testing the Gamma-ray Burst Pulse Start Conjecture

We test the hypothesis that prompt gamma-ray burst (GRB) pulse emission starts simultaneously at all energies (the Pulse Start Conjecture). Our analysis, using a sample of BATSE bursts observed with four-channel, 64 ms data and performed using a pulse-fit model, generally supports this hypothesis fo...

Zusammenfassung:	We test the hypothesis that prompt gamma-ray burst (GRB) pulse emission starts simultaneously at all energies (the Pulse Start Conjecture). Our analysis, using a sample of BATSE bursts observed with four-channel, 64 ms data and performed using a pulse-fit model, generally supports this hypothesis for the Long GRB class, although a few discrepant pulses belong to bursts observed during times characterized by low signal-to-noise ratio, hidden pulses, and/or significant pulse overlap. The typical uncertainty in making this statement is
