Optical Strong Line Ratios Cannot Distinguish Between Stellar Populations and Accreting Black Holes at High Ionization Parameters and Low Metallicities
Nikko J. Cleri, Grace M. Olivier, Bren E. Backhaus +24
High-redshift observations from JWST indicate that optical strong line ratios do not carry the same constraining power as they do at low redshifts. Critically, this prevents a sepa…

Evidence for evolutionary pathway-dependent black hole scaling relations
Jonathan H. Cohn, Emmanuel Durodola, Quinn O. Casey +2
Recent observations have identified an abundance of high-redshift active galactic nuclei (AGN) with supermassive black holes (BHs) that are over-massive compared to the local BH ma…
