Using simultaneous modeling of continuum lag-spectrum and broadband SED of Fairall 9 with the H0RIZON-AGN model, the authors obtain H0 = 72.4_{-3.7}^{+3.4} km s^{-1} Mpc^{-1}.
Slim-disk self-shadowing plus accretion-rate-dependent BLR density enhancement explains the observed offsets of high-Eddington AGNs below the canonical R-L relation.
Disk reflection from a compact lamp-post corona explains the X-ray polarization and spectra of NGC 4151.
Simultaneous observations of NGC 4151 and UGC 3374 show that ICCF-Cut photometric Hα light curves and lags match spectroscopic results within uncertainties, with minor discrepancies attributed to He I contamination that can be corrected.
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.
