Direct detection of CO(3-2) at z=7.31 in REBELS-25 gives M_mol ~ 10^11 M_sun with f_gas ~0.95, confirming a massive molecular reservoir and showing low-J CO remains detectable in the Epoch of Reionization.
Detection of a stellar bar in the extreme gas-rich galaxy GN20 at z=4.055 shows that gas-rich disks support rapid bar formation in the early universe.
New JWST data on 23 galaxies at 0.5<z<1.7 show median dark matter fraction of 0.63 at effective radius with 0.2 dex scatter, and a mix of rising, flat, and falling rotation curves.
Simulations of high-redshift galaxies show the 1719 Å UV index reliably traces stellar metallicity while others are more sensitive to star formation history.
Simulations from COSMOS2020 show masking recovers [CII] above 300 GHz in ideal conditions but noise prevents useful S/N until near the end of 2000-hour observations.
