On the PDS of GRB light curves
Abstract
In spite of the complicated behavior in the time domain, long GRBs show a simpler behavior in the Fourier domain of frequencies, represented by power density spectra, PDS. Recently, there are some relations found between GRBs properties and PDS parameters, modeled by power-laws. Among them, the correlation between peak energy and PDS slope shows a clear evidence. In this work we try to understand the origin of this correlation, making use of synthetic pulses. We find some preliminary evidences that relation can be seen as a new confirmation of the empiric relations and for GRBs.
