Key Details

JWST finds more early supermassive black holes than expected

Mass ratios match gravitational wave data better than local active galactic nuclei

Suggests most local supermassive black holes are in inactive galaxies

Favors detectability of gravitational waves from black hole binaries

Can explain higher than expected fraction of dual active galactic nuclei

AI generated summary

JWST reveals abundance of early supermassive black holes, consistency with gravitational wave data

New JWST observations have revealed an unexpected abundance of supermassive black holes in the early universe. This paper argues these discoveries are consistent with gravitational wave measurements from NANOGrav, suggesting most local supermassive black holes reside in inactive galaxies.
