Baryonic fraction in certain galaxies correlates with baryonic acceleration as approximately a_bar inverse, placing known dark-matter-deficient galaxies at the high-acceleration extreme and predicting low dark matter content for ultra-diffuse galaxies brighter than 25 mag arcsec^{-2}.
Simulations of dwarf galaxies show V/σ rising with stellar mass, with HI gas and young stars more rotation-supported than old stars.
New FUV SFRs for the full SHIELD sample confirm Hα underestimates star formation in dwarfs, establish FUV as robust at lowest masses, and identify baryonic mass as the best predictor with most galaxies gas-dominated.
A unified HI rotation curve database for 129 Local Volume dwarf and irregular galaxies with standardized parameters, quality tiers, and machine-readable formats.
Simulations constrain the mass scale for efficient ISM stripping of dwarf satellites to M_star ≲ 10^7 M_sun in MW-like halos, 0.5-1 dex below observed values, indicating additional quenching mechanisms are needed.
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.
