Primordial black holes and heavy astrophysical seeds with super-Eddington accretion reproduce JWST-observed black hole masses, stellar masses, and low metallicities at z~7-10, while light seeds with Eddington-limited accretion are ruled out; PBHs uniquely show a decreasing black hole-to-stellar mass

Coevolving super-Eddington black holes and nuclear starbursts in high-redshift halos naturally generate the V-shaped UV-to-optical spectra and weak high-energy emission of little red dots.
Five LRDs at z≈2 yield number density ≈7×10^{-6} cMpc^{-3}, confirming a decline from the z≈5 peak but gentler than prior photometric estimates.
Simulations show heavy-seed formation with BH-BH mergers or Bondi accretion under weak feedback can assemble 10^6-10^7 solar mass black holes at z greater than or equal to 9.
Rapid halo growth in SEEDZ simulations enables heavy black hole seed formation via supermassive stars at a comoving number density of 0.1 cMpc^{-3} by z=10, with most seeds in near-solar metallicity gas.
Simulations and analytic modeling predict that the supermassive black hole to stellar mass ratio peaks at several percent around redshift 7-10 before declining toward the present day.

Light, heavy, primordial: exploring the diversity of black hole seeding and growth mechanisms in the JWST era
