"Little red dot" in early Universe is a naked supermassive black hole

Astronomers modeled QSO1 and found a ~50 million-solar-mass black hole with very little surrounding stellar mass.

The host galaxy appears so small that its stellar mass may be lower than the black hole’s mass, making QSO1 unusually “bare.”

That rules out growth in a dense stellar cluster and leaves more speculative origins, such as direct-collapse or primordial formation.

The finding challenges standard ideas about how supermassive black holes and galaxies formed in the early Universe.
