A changing-look AGN exhibits a rapid accretion-driven spectral transition with broad-line region temperatures of approximately 11,800 K measured via Boltzmann plots and stable black hole mass estimates of 5 times 10 to the 7 solar masses across epochs.
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 structure function slopes rising from 0.1 to 0.3 with black hole mass, no breaks on decadal scales, amplitude anticorrelated with luminosity and positively correlated with mass.
A criterion of |Δg| > 0.4 mag and |Δ(g-r)| > 0.2 mag detects photometric CL-AGN transitions in 9.6% of known hosts with 1.6% false positive rate from simulations.
High-resolution GRMHD simulations show that tearing of tilted accretion disks around rapidly spinning supermassive black holes drives order-of-magnitude variability in continuum and broad-line luminosities on months-to-years timescales, explaining changing-look AGN.
New Gemini/GNIRS observations of star-forming radio galaxies show warm H2 emission driven primarily by mergers rather than jets.
CL-AGN host galaxies exhibit a 29% merger fraction (about 2x higher than non-CL-AGN controls) with morphology indicating modest disturbances, based on non-parametric metrics and visual inspection of DESI images.
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.
Systematic search of ZTF DR23 data yields catalogs of 28,504 coarse and 1,984 refined AGN flares with public release.
Multi-wavelength data from SDSS J1430+2303 are interpreted as evidence that radiation pressure instabilities drive a shrinking unstable accretion-disk zone, based on timing analysis, weak soft excess, and SED-derived black-hole parameters.
Multi-epoch spectroscopic cross-matching yields 45 CLAGNs (43 turn-off, 2 turn-on) including 12 repeating sources that trace a high-low-high accretion-state path in the black-hole mass versus Eddington-ratio plane.
A model of accretion-disk dynamos as synchronized macro-spins unifies broadband variability, coronal heating, jets, and hard/soft cycles via collective spin dynamics.
LAMOST DR10-12 adds 11,346 quasars (5,386 new) with ZTF-recalibrated spectra and derived emission-line and black-hole mass properties to support variability and rare-object studies.
