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}.

The Sagittarius dwarf progenitor had a metallicity gradient of roughly -0.3 dex per kpc prior to infall.
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.
Forecasts indicate CSST can detect wide binaries in Segue 1 down to fb ~ 0.01 with 2300 stars but needs 6000 stars and fb ~ 0.1 to distinguish cusped from cored dark matter profiles.
The PFS Galactic Archaeology survey will observe thousands of stars in Local Group systems to measure density profiles in dwarfs and compare assembly histories of M31 and the Milky Way.
New non-LTE abundances for three Bootes I stars show an alpha-element transition at [Fe/H] between -3 and -2, interpreted as the onset of type Ia supernova contributions in this ultra-faint dwarf galaxy.

Contribution of type Ia supernovae to the chemical enrichment of the ultra-faint dwarf galaxy Bootes I
New non-LTE abundances for three Bootes I stars show an alpha-element transition at [Fe/H] between -3 and -2, interpreted as the onset of type Ia supernova contributions in this ultra-faint dwarf galaxy.
