James Webb's 'too massive' galaxies may be even more massive (phys.org)

For the discovery of those ‘too massive galaxies’ you can look at the following paper:

A population of red candidate massive galaxies ~600 Myr after the Big Bang

Apparently there are a lot of amazing papers about to come out https://twitter.com/andrasgaspar/status/1658914819100098560?...
