Non-Stationarity of Active Galactic Nuclei
Abstract
Through cross-examining a sample of Active Galactic Nuclei (AGN) in both the Sloan Digital Sky Survey (SDSS) and Hyper Suprime-Cam survey (HSC), we examine the stationarity assumption used in many AGN variability studies. We find that over an average of 15 years, our AGN dim between their SDSS and HSC measurements. This decrease in flux goes against the aforementioned stationarity assumption, and we investigate this phenomenon in further detail in an upcoming paper.
