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.

Introduces a semi-deterministic star sampling method in simulations that derives the instantaneous IMF from current cluster mass using reservoir particles and on-the-fly cluster finding.
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.
A model based on Chandrasekhar's 1951 time-invariant quantity quantitatively explains the Mach-number dependence of the density power spectrum slope in isothermal supersonic turbulence and demonstrates that the slope cannot reliably determine the Mach number.
Multiphase observations show molecular gas mass loading factors 10 times higher than ionised gas in ESO 484-036, creating a 3.5 dex discrepancy with cosmological simulations that underpredict cold gas outflows.
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.
Massive young star clusters clear their natal gas faster than lower-mass clusters, based on HST and JWST imaging of four galaxies.
New CO survey of 62 CALIFA galaxies shows median molecular gas depletion times rising from 2.1 Gyr on the main sequence to 128 Gyr in red galaxies, with SFE declining systematically below the SFMS independent of CO-to-H2 conversion factor choice.
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.
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.
Dwarf irregular galaxies form stars sequentially in dispersed HI clouds and on expanding cavity rims at ~1% efficiency per free-fall time, comparable to spiral galaxy clouds but without CO due to lower metallicity.
The chapter proposes SKA spectroscopic surveys of the inner and outer Milky Way using OH, CH, radio recombination lines, and H2CO to study molecular cloud formation, ionized gas properties, and CO-dark molecular gas.
