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.
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.
