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…
Multivariate Continuous-Time Autoregressive Moving Average Processes for Astronomical Multiband Time Series
Izak Schmidlkofer, Zhirui Hu, Lishan Shi +2
Large-scale astronomical surveys provide unprecedented volumes of multivariate time-series observations obtained through multiple optical filters. We develop a structured multivari…
Modeling Dependence Structures in Astronomical Multi-Band Time Series Data via Multi-Output Gaussian Processes
Samata Das, Lishan Shi, Yasaman Hamayouni +2
Modern astronomical time-domain surveys routinely collect multi-band light curves that provide complementary information about the physical processes governing source variability.…
