"Last year when we first published our work on very high redshift z>11 in SMACS 0723 we were very badly smashed."

Yan et al. used a stricter selection filter, but z_photometric > 13 galaxies still don't show the expected rapid evolution.

"It is very exciting that @Richarwirman’s @ceers_jwst
DDT observations of #MaisiesGalaxy and @CdonnanAstro’s galaxy were obtained overnight. The @ceers_jwst and Edinburgh teams are hard at work on a joint paper, and we will be excited to share our results here when we submit!"
Maisie's galaxy at z ≈ 14.3
(The age at z was ≈ 290 Myr.)

"Maisie's galaxy, however, appears to be confirmed to be at very high-z 🥳 !"

"... these trends suggest that galaxies with established disks and spheroids exist across the full redshift range of this study and further work with large samples at higher redshift is needed to quantify when these features first formed"
