As an example, the image below shows how early galaxies of different masses (each row) would look if we could see the brightness in all stars (left), or the stars weighted by age (middle), or just what JWST can see (right). As powerful as JWST is, there's a lot going on that it can't resolve!

This is what I assume is an AI-generated short form article on our paper that came out almost coeval with us dropping it on the arXiv … And honestly, it’s a pretty good popular science level summary.

The formation of galactic disks is a surprisingly tough topic to understand. In a great paper, UCI grad student Olti Myrtaj shows how and why the Milky Way disk undergoes 3 distinct phases (chaotic -> thick disk -> thin disk). A thin disk requires a virialized inner CGM and slow(er) gas accretion. 🧪

This is what the most distant confirmed galaxy looks like. The light we're receiving was emitted when the Universe was ~15x smaller in linear size than today, and right now it's ~30 billion light-years away from us. The light was emitted when the Universe was <300 million years old. Pretty amazing!
