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.
A z=1.715 radio-loud quasar exhibits a ~10,000 K blackbody UV continuum and three-component blackbody photometry, marking it as a candidate transitional Little Red Dot.
A bias-controlled quasar sample of ~2000 objects demonstrates that the X-ray-to-UV luminosity relation remains constant from redshift 0.7 to 5.
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.
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.
