JWST Finds Black Holes That Precede Galaxies in the Early Universe
TL;DR Summary
Using JWST, astronomers study a triply lensed background galaxy Abell 2744-QSO1 at z=7.04 and measure a central black hole of about 50 million solar masses concentrated with little surrounding stellar mass, providing strong evidence that supermassive black holes formed before their host galaxies and favoring heavy-seed formation scenarios in the early universe.
