Lumen modeling of IllustrisTNG50 shows that high ionization parameters from massive star clusters plus enhanced nitrogen abundances are needed to reproduce the extreme [OIII]/Hβ, [OIII]/[OII], and [NII]/Hα ratios seen in z>3 galaxies.

COLIBRE simulations find the galaxy gas-phase MZR already in place at z≈10 with little evolution until z≈5, then shallowens at low z, with high-mass turnover set by AGN feedback and low-mass end by core-collapse supernovae.
ALMA CO observations of NGC 4565 reveal a thin non-flaring molecular disk with a central gap, consistent GMC properties to 17 kpc, and a prominent star-forming ring feature.
Observational study of MBM12 shows CO-to-H2 conversion factor near galactic average with density-dependent variations, high virial parameters decreasing at small scales, broken power-law mass-size relations indicating external pressure, and magnetic field orientation transition at N(H2) = 4.5e21 cm-
Observational study of 100 LMC GMCs finds median 13CO(2-1)/12CO(2-1) line ratio of 0.078, nearly linear with luminosity, and higher in clouds hosting IR-bright young stellar objects.
Molecular gas in M83 consists of two log-normal density components, with the high-density component enhanced along spiral arms and more tightly linked to star formation than the low-density component.
ALMA CO data in NGC 3351's CMZ shows a size-linewidth slope of 0.58, ordered motions stronger above 30 pc and random motions below, with free-fall times comparable to ordered crossing times across scales.
