Filament dark matter density profiles become nearly universal when scaled by terminal halo virial radii, with the inner cusp produced by embedded halos and the smooth component showing a flat core that evolves from smooth to clumpy accretion.

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}.
An improved distribution-function modeling technique applied to thousands of stars yields a 4 million solar-mass central black hole and a total mass of 2.0-2.3 x 10^7 solar masses within 10 pc of the Milky Way nucleus.
Milky Way-mass dark matter density profiles in IllustrisTNG are largely insensitive to astrophysics and cosmology variations, dominated by halo-to-halo variance instead.
