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.
Clustered dark matter may enable small seed black holes to grow to over 10^7 solar masses by redshift 10 in dense nuclear star clusters, with special behavior for ultralight dark matter due to its de Broglie wavelength.
