Abstract and keywords

Abstract (English):
We present a study of the multiwavelength (MW) variability of the blazar AO 0235+164 based on the radio-to-

γ

-ray data covering a period from 1997 to 2023. The radio data are represented by the measurements from the SAO RAS, IAA RAS, and CrAO RAS telescopes. The optical measurements were collected with the SAO RAS 1-m and 0.5-m reflectors. The archive data at 230 GHz from the Submillimeter Array and the

γ

-ray data from the Fermi-LAT mission were used too. A significant correlation between different spectral bands is found with time delays up to 1.7 years. The relation between time delay and frequency is well described by a linear law. The revealed features of MW variability for the quiet period and for flaring states suggest that the mechanisms dominating the radio-

γ

-ray variations are not substantially different. AO 0235+164 shows a total variability period of

\sim

6 years for all wavelength bands, and 1.4-2.3 years during the low state, which may reflect its general properties.
