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.
High-z LRDs and JWST AGN exhibit X-ray weakness consistent with local super-Eddington accreting SMBHs, supporting a link to highly accreting systems across cosmic time.
Outliers from the black hole-stellar mass scaling relation arise from distinct channels of enhanced mergers with super-Eddington growth, gravitational recoils after mergers, environmental stellar mass loss, and quiescent histories.

The X-ray weakness of Little Red Dots and JWST-selected AGN: comparison with local AGN in different accretion regimes
High-z LRDs and JWST AGN exhibit X-ray weakness consistent with local super-Eddington accreting SMBHs, supporting a link to highly accreting systems across cosmic time.

Overmassive and Undermassive Massive Black Holes: The Role of Environment and Gravitational-Wave Recoils
Outliers from the black hole-stellar mass scaling relation arise from distinct channels of enhanced mergers with super-Eddington growth, gravitational recoils after mergers, environmental stellar mass loss, and quiescent histories.
