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.
Recent observations by the James Webb telescope suggest that supermassive black holes may have formed before galaxies, possibly from primordial black holes or dark matter collapse, challenging previous theories about their origins and indicating that such phenomena are less exotic than once thought.
Astronomers using the James Webb Space Telescope have discovered QSO1, a supermassive black hole of 50 million solar masses that appears to be rogue and without a galaxy, challenging existing theories of black hole formation and suggesting it may be a primordial or direct-collapse black hole formed in the early universe.
