Beyond the Damped Random Walk: Multiband AGN Variability from SDSS to Rubin LSST

Izak Schmidlkofer, Zhirui Hu, Weixiang Yu +1

The flux variability of Active Galactic Nuclei (AGNs) is commonly modeled using the damped random walk (DRW), but increasingly rich multiband time-domain surveys motivate more flex…
