Direct collapse black holes born at z=25.7 grow at half-Eddington rate to produce overmassive black hole galaxies at z~10 with M_BH/M_* ~0.01, matching JWST observations of GN-z11, UHZ1, and GHZ9 through initial star-formation suppression and later Pop III supernova metal blowout.

ArkenstoneBH is a new subgrid model for the hot phase of black hole feedback that, in isolated galaxy tests, suppresses star formation by counteracting gas inflows from the circumgalactic medium.
UV-bright companions to Little Red Dots provide Lyman-Werner fluxes of J21 ~ 10^2.5-10^5 that can suppress H2 cooling and enable direct collapse to massive black holes.
Non-LTE wind atmosphere models computed with CMFGEN reproduce the SED and Balmer decrement of most Little Red Dots when dust-attenuated with Av ~2, while predicting Fe II, O I, and Ca lines, but struggle to produce both a genuine Balmer break and strong lines simultaneously.

How Overmassive Black Holes Formed at Cosmic Dawn
Direct collapse black holes born at z=25.7 grow at half-Eddington rate to produce overmassive black hole galaxies at z~10 with M_BH/M_* ~0.01, matching JWST observations of GN-z11, UHZ1, and GHZ9 through initial star-formation suppression and later Pop III supernova metal blowout.

Connecting the Dots: UV-Bright Companions of Little Red Dots as Lyman-Werner Sources Enabling Direct Collapse Black Hole Formation

Non-LTE atmosphere models of very luminous sources and their applicability to Little Red Dots, quasi-stars, and similar objects
Non-LTE wind atmosphere models computed with CMFGEN reproduce the SED and Balmer decrement of most Little Red Dots when dust-attenuated with Av ~2, while predicting Fe II, O I, and Ca lines, but struggle to produce both a genuine Balmer break and strong lines simultaneously.
