Optical continuum lags in NGC 4395 remain stable at 5-15 minutes over multi-year baselines with negligible diffuse continuum contribution.
Turbulent electron-ion coronae around accreting black holes self-regulate into a two-temperature state that generates nonthermal ions and X-ray spectra consistent with observations including an MeV tail.
A Chimera accretion flow can sustain MAD-level horizon flux and electromagnetic jet power without the standard MAD's eruptive variability, mass-flow geometry, or inner-disk morphology, so MAD-like behavior is multi-diagnostic and history-dependent.
Bayesian analysis of LISA EMRIs in AGN disks constrains disk surface density and accretion rate to ~10% using relativistic torque models, invalidating Fisher-matrix forecasts and enabling dark-siren cosmology without EM counterparts.
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.
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.
Requiring thin-disk solutions to be thermally stable and single-valued imposes η_x ≡ dlnα/dlnX > 4/7, and a viscosity law α∝X^p with p>4/7 removes the radiation-pressure unstable branch.
Migration traps concentrate stellar-mass black holes in AGN disks, generating self-regulated magnetic reconnection heating that yields excess short-timescale optical/UV variability, flattened structure functions, and deviations from the τ∝λ^{4/3} lag relation.
HE 1237-2252 exhibits a changing-look event driven by intrinsic accretion-rate variations, revealing a two-component broad-line region consisting of virialized gas at ~27 light-days and disk emission at larger radii.

The SANE, the MAD, and the Chimera
A Chimera accretion flow can sustain MAD-level horizon flux and electromagnetic jet power without the standard MAD's eruptive variability, mass-flow geometry, or inner-disk morphology, so MAD-like behavior is multi-diagnostic and history-dependent.
