Galaxy Zoo JWST: Up to 75% of discs are featureless at 3 < z < 7 [PDF]

Monthly notices of the Royal Astronomical Society
We have not yet observed the epoch at which disc galaxies emerge in the Universe. While high-z measurements of large-scale features such as bars and spiral arms trace the evolution of disc galaxies, such methods cannot directly quantify featureless ...
