The recent findings from the James Webb Space Telescope (JWST) have identified six candidate massive galaxies with stellar masses exceeding 1010 solar masses, existing as early as 500-700 million years after the Big Bang, challenging the LambdaCDM model of cosmology. The study, published in Nature, highlights that these observations contradict previous predictions which suggested galaxy formation should occur much later, specifically after redshift z=7. The implications of these findings suggest a significant reevaluation of galaxy formation theories and the LambdaCDM model's accuracy. This research marks a pivotal moment in our understanding of the early universe.
PREREQUISITESAstronomers, astrophysicists, and cosmologists interested in the evolution of the universe, as well as students and researchers studying galaxy formation and the implications of new astronomical observations.
Doubtful. They don'y even have a real redshift - just photometry.BWV said:

Stacy McGaugh's blog Triton Station is probably a better source for what's going on with actual data vs theories. He has just now (10-Mar-2023) put out a new post about this. One of the things he reminds is that this business about "big galaxies early" was a prediction of MOND. See his post from 3-Jan-2022.pinball1970 said:
More of a Freudian slip. Photometric redfshifts are little better tnan "Golly, it sure looks red". Yes, someimes that's all you have, but it's hard to get excited until the real data - i.e. spectroscopic redshifts - come in.strangerep said:OK, this is definitely one of your typos you should definitely fix.
Agreed. The papers will be published and bloggers and YouTubers will comment including The Hoss and others but ultimately, it will be discussion on PF that will make sense of it all. To me at least.Vanadium 50 said:
