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.
A 6D kinematic census identifies 18 anomalous Cepheids with extreme orbits, including one possibly scattered by globular cluster E3, and finds consistency between dynamical and stellar ages.
Realistic ISM fluctuations from TIGRESS-NCR MHD simulations drive stellar radial heating with σ_R ∝ t^{1/2} (early, cold) and t^{1/5} (late, warm) plus substantial migration explained by quasilinear theory with λ_* ~600 pc and τ_* ~70 Myr.
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.
Kpc-resolution ALMA CO and dust maps of three z~3 dusty galaxies are consistent with gravo-turbulent star-formation models rather than non-turbulent predictions.
A multiphase ISM grain-size model with low supernova dust yield reproduces observed dust-to-stellar mass ratios and UV luminosity functions at z=7-12 by letting small grains seed rapid metal accretion.
BonFIRE and CampFIRE simulations show bursty clustered star formation in early galaxies and predict UV luminosity functions matching observations at faint magnitudes with a turnover at M_UV approx -14 but overpredicting brighter galaxies.
The Milky Way disk spin-up to rotationally supported motion occurred at mean age 12.1 Gyr for -1.25 < [Fe/H] < -0.9, traced by high-alpha stars, while low-alpha stars show no transition and start at disk-like velocities.
TNG50 shows most massive high-z star-forming galaxies are dynamically hotter than ALMA data indicate, with rare cold discs forming from aligned accretion and evolving into one-third discs and two-thirds early-type galaxies by z=0.
Simulations show that observed rotation in 13.5-Gyr-old alpha-rich stars constrains the Gaia-Sausage-Enceladus merger to mass ratios below 1:4, with interaction and starburst times both near 11 Gyr.
Simulations show that bursty supernova feedback produces fewer bright [OIII] emitters by z=5 than smooth feedback due to less effective metal enrichment, while [OIII] traces shock-heated and radiatively ionized gas.

Interstellar Medium-Driven Orbital Transport -- I. Radial Heating and Migration
Realistic ISM fluctuations from TIGRESS-NCR MHD simulations drive stellar radial heating with σ_R ∝ t^{1/2} (early, cold) and t^{1/5} (late, warm) plus substantial migration explained by quasilinear theory with λ_* ~600 pc and τ_* ~70 Myr.
