James Webb Space Telescope spots rare red spiral galaxies in the early universe

"Astronomers analyzed red spiral galaxies in one of the James Webb Space Telescope's first images, that of the galaxy cluster SMACS J0723.3–7327. Seen through the eyes of JWST, the most powerful telescope ever placed into orbit, the galaxy cluster magnifies objects seen behind it, letting astronomers see deeper into the universe. The researchers determined that some of these galaxies represent the most distant spiral galaxies ever seen."

Spiral galaxies are very interesting and now reports where they show up with deep redshifts. Spiral arms last perhaps 80-100 million years, and then must be regenerated for astronomers on Earth today to see the spiral structures like the Milky Way, so modeling density waves and spiral arm recycling is required for long ages used in BB cosmology. Here are some other reports I read on this topic.

My notes. The report is 6-page PDF file. From the published report. "4. Results and Discussion 4.1. SED Fitting Results We found that the redshifts of extremely red spirals are in a range of zph = 1–3. In particular, RS 14 (zspec = 2.463) is one of the highest redshift spiral galaxies identified so far (Dawson et al. 2003; Law et al. 2012; Margalef-Bentabol et al. 2022; Wu et al. 2022)."

My note. Using cosmology calculators, H0=69.6 km/s/Mpc, z=2.463. Age of universe at z = 2.688 Gyr. Look back distance or light time = 11.034 Gyr. The universe radius when these early spirals appeared, about 5.56 Gly or less than 12 billion light years diameter compared to present day, about 93 billion light years diameter. The comoving radial distance for z = 2.463 is 19.224 Gly. 4D space is expanding 1.36 x c velocity. https://lambda.gsfc.nasa.gov/toolbox/calculators.html

When explaining and interpreting early spirals like this report, the cosmology parameters documented are required for the BB cosmology to work. Here is another report on JWST seeing 13.2 redshifts with discussion on various parameters required to explain and photons losing energy as they redshift traveling through 4D space expanding, even expanding faster than c velocity. https://forums.space.com/threads/co...e-has-bagged-the-oldest-known-galaxies.59123/
