METHODS FOR ANALYZING THE LIGHT CURVES OF THE NON-THERMAL RADIATION IN ACTIVE GALACTIC NUCLEI
Аннотация и ключевые слова
Аннотация (русский):
We present different methods for analyzing the light curves of active galactic nuclei (AGNs). Based on the example of AGN multiwavelength measurements, features of the following methods are considered: (1) structure functions (SFs)—to search for variability timescales; (2) discrete correlation functions (DCFs)—to search for connections between processes; (3) the Lomb–Scargle (L–S) periodogram—to search for periodicity. We analyze advantages and disadvantages of the methods and discuss their constraints and interpretation.
