Blind tests on simulated disc-wind BLR data show standard RM methods recover rotation but miss wind geometry and yield inconsistent velocity-delay maps despite good spectral fits.
JWST observations of ERQs show stratified gas kinematics via deblended optical emission lines, with UV lines dominated by scattered light and optical lines mixing scattered and obscured emission.
Low-luminosity AGN exhibit optical variability structure function slopes that increase with black hole mass from ~0.1 to ~0.3, with amplitude anticorrelated with luminosity, no breaks observed, and variability continuing to rise on 20-year timescales.
Reverberation lags in Mrk 817 range 3-8 days, exceed thin-disk models by factors of 3-6, follow a λ^{4/3} trend with the ICCF method, and vary by up to a factor of 2 between epochs.
