Abstract (from CDS):

We have studied power density spectra (PDS) of 206 long gamma-ray bursts. We fitted the PDS with a simple power law and extracted the exponent of the power law (α) and the noise-crossing threshold frequency (fth). We find that the distribution of the extracted α peaks around -1.4 and that of fth around 1 Hz. In addition, based on a subset of 58 bursts with known redshifts, we show that the redshift-corrected threshold frequency is positively correlated with the isotropic peak luminosity. The correlation coefficient is 0.57±0.03.
