Publisher summary· verbatim

arXiv:2611.15040v1 Announce Type: cross Abstract: The optical continuum variability of quasars is often described by a damped random walk (DRW) model, with characteristic damping timescales $\tau_{\rm DRW}$ of hundreds of days and amplitudes $\sigma_{\rm DRW}$ of $\mathcal{O}(0.1)$ magnitudes.
