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…

Modeling Stochastic Variability in Multi-Band Time Series Data
Zhirui Hu, Hyungsuk Tak
In preparation for the era of the time-domain astronomy with upcoming large-scale surveys, we propose a state-space representation of a multivariate damped random walk process as a…
