Improved Methods for Power Spectrum Modelling of Red Noise

WebWe discuss techniques of modelling the power spectrum of variability in cases where the spectral power is continuous but diverges strongly to low frequencies (so-called `red noise'), as is seen, for example, in the erratic variability of active galaxies and X-ray binaries. First we review the sampling properties of the periodogram and traditional … Web27 de abr. de 2016 · The variation can typically be characterized by a broadband power spectrum, which exhibits a red-noise process at high frequencies. The standard method of estimating power spectral density (PSD) of AGN variability is easily affected by systematic biases such as red-noise leakage and aliasing, in particular, when the observation … north east weather forum
