MoM-BH*-1 Links 660-Million-Year-Era Black Hole Star to JWST's Little Red Dots

Summary
MoM-BH*-1, seen less than 660 million years after the Big Bang, is the clearest "naked" black hole star yet and offers the strongest direct clue to what powers JWST's little red dots.
JWST spectra show a gas cloak feeding an early black hole whose hidden accretion lights the surrounding cloud, producing the red, star-like signature that has puzzled astronomers since 2022.
Modeling suggests that if MoM-BH*-1 merges with a nearby young galaxy in about 100 million years, the combined system would resemble the little red dots already found at galactic centers.
That supports the idea that black hole stars are central engines of baby quasars, tracing how fast-growing black holes in the early universe may have formed before or alongside their host galaxies.
Could dense gas be tricking us into overestimating the size of the universe's earliest supermassive black holes by a hundredfold?
If dust isn't hiding the early universe's most massive black holes, what other fundamental cosmic rules have we completely misunderstood?
Overmassive Black Holes in the Early Universe: JWST’s Discovery of Gas-Shrouded "Little Red Dots" and the Challenge to Galaxy Evolution Models
Overview
The James Webb Space Telescope (JWST) revolutionized our view of the early universe by uncovering mysterious 'Little Red Dots'—compact, gas-shrouded objects that infrared observations revealed to be rapidly growing supermassive black holes. By combining JWST’s data with deep X-ray observations, astronomers confirmed these black holes were hidden by dense cocoons, explaining why earlier telescopes missed them. These black holes grew much faster than expected, often outpacing their host galaxies and challenging traditional models of cosmic evolution. As the universe matured, powerful winds from these black holes cleared away surrounding gas, allowing them to shine as brilliant quasars and shape the growth of their galaxies.
