Variability of Active Galactic Nuclei in Accretion Disks
ÖffentlichA damped random walk (DRW) is a stochastic process defined by its exponential covariance matrix, which behaves as a normal random walk for short time scales and asymptotically achieves a finite variability amplitude at long time scales. The DRW is employed to provide a statistical description of observed Active Galactic Nuclei (AGN) variability in the optical wavelength range 620 to 750 nm. The best fitting DRW, posterior probability distributions for the fitted DRW parameters, and the binned power spectral density alongside its autocorrelation function are fitted for an AGN and provide insight into the optical variability for an AGN.
