Spectral fitting of The Cliff LRD with Bagpipes yields a BH*-like solution with a low-mass metal-poor host, moderate dust, smooth star formation history, and high BH-to-stellar mass ratio.

Two z~6.6 galaxies host overmassive black holes and show remnant ionized bubbles from recent quasar episodes, with BH-to-stellar mass ratios 400-800 times above the local relation.
JWST broad-line AGN lack X-ray and high-ionization signatures, consistent with super-Eddington accretion that suppresses those emissions without heavy dust.
A large collaboration compiles and compares merger rate predictions for massive black holes across multiple galaxy formation models to forecast LISA detections and quantify uncertainties.

The case for super-Eddington accretion in JWST broad-line AGN during the first billion years
JWST broad-line AGN lack X-ray and high-ionization signatures, consistent with super-Eddington accretion that suppresses those emissions without heavy dust.
