Environmental segregation between early-type and late-type galaxies weakens with decreasing stellar mass and vanishes in the dwarf regime, where internal processes dominate galaxy evolution.
The Milky Way is a kinematic outlier, with 2-3 times lower stellar velocity dispersion per unit rotation speed at a given age than all but one observed disk galaxy, and most cosmological simulations match other galaxies but not the Milky Way.
Galaxies become less concentrated, more asymmetric and less clumpy toward lower stellar masses, with bar fraction declining to zero near 10^8 solar masses and CAS parameters losing separating power in the dwarf regime.
JWST measurements of pitch angles in 593 spiral galaxies to z=3.5 show no overall redshift evolution but reveal correlations with mass and sSFR only below z=1.25, implying a transition from locally driven to globally regulated spiral arms.
FIRE-2 simulations find metallicity gradients in EoR galaxies flatten from median -0.15 dex/kpc at z~10 to -0.1 at z~6, with positive correlations to stellar mass and gas flow proxy Δv/2σ and links to central SFR density.
Simulated galaxies with on-the-fly dust evolution appear brighter-centered and more bulge-dominated in mock JWST images than with a fixed dust-to-metal ratio, lowering the measured late-type fraction at high redshift.
Galactic flat rotation curves and the acceleration scale a0 are attributed to slow time-dependent growth of galaxy mass and radius, rather than dark matter or modified gravity.
FIRE simulations show that the inner CGM of halos below ~10^12 Msun is cool and supersonically turbulent before hot-phase formation, and this turbulence naturally yields the ~1 angstrom equivalent width UV absorbers observed around star-forming galaxies.
For 24 rotating disks at z about 2, specific angular momentum scales with stellar mass as j_star proportional to M_star^0.25, significantly shallower than the local beta of about 0.67.
FIRE-2 simulations show that stellar radial redistribution scatter saturates at ~2 kpc for stars older than ~3 Gyr, with net orbital changes depending on age and current radius, broadly matching Milky Way observations.
IC 2531's geometrically defined thick disc is, on average, older, more metal-poor and similarly alpha-enhanced relative to its thin disc, resembling the Milky Way's chemical discs.

The relationship between morphology, density, and location in the cosmic web from massive to dwarf galaxies
Environmental segregation between early-type and late-type galaxies weakens with decreasing stellar mass and vanishes in the dwarf regime, where internal processes dominate galaxy evolution.

Stellar Velocity Dispersion versus Age: Consistency across Observations and Simulations, with the Milky Way as an Outlier
The Milky Way is a kinematic outlier, with 2-3 times lower stellar velocity dispersion per unit rotation speed at a given age than all but one observed disk galaxy, and most cosmological simulations match other galaxies but not the Milky Way.

Global trends in morphology from massive to dwarf galaxies
Galaxies become less concentrated, more asymmetric and less clumpy toward lower stellar masses, with bar fraction declining to zero near 10^8 solar masses and CAS parameters losing separating power in the dwarf regime.

Spiral arms across cosmic time: JWST measurements of the pitch angles of spiral galaxies at $z<3.5$
JWST measurements of pitch angles in 593 spiral galaxies to z=3.5 show no overall redshift evolution but reveal correlations with mass and sSFR only below z=1.25, implying a transition from locally driven to globally regulated spiral arms.

Turbulence-dominated CGM: the origin of UV absorbers with equivalent widths of $\sim1$\AA
FIRE simulations show that the inner CGM of halos below ~10^12 Msun is cool and supersonically turbulent before hot-phase formation, and this turbulence naturally yields the ~1 angstrom equivalent width UV absorbers observed around star-forming galaxies.
