Webb and ALMA reveal a dusty, rapidly growing early black hole

J1440+0019 holds a black hole about 1.1 billion times the Sun's mass, from when the universe was less than a billion years old, according to phys.org (https://phys.org/news/2026-10-jwst-alma-reveal-dusty-rapidly.html). It is radiating at about 80% of its Eddington luminosity, a pace that marks it as rapidly accreting.
