OK... so the galaxy’s spectra are what you’d expect from a galaxy that’s way beyond the farthest known galaxy... but the spectra could also be skewed by fact that it’s simply spinning away from us extra-fast because it’s spinning around a parent galaxy? Couldn’t add THAT much extra speed? And what does a huge number of newborn stars have to do with redshift?
Before a star has accreted enough mass to ignite its nuclear fire, I assume that it gives off a huge amount of infra-red radiation as it gets hotter and hotter..................
