SIDM simulations of dwarf halos show that quiescent merger histories produce gravothermal core collapse while sustained mergers prevent collapse and can yield central densities below gravothermal fluid model predictions.

Dwarf spheroidal galaxies evolve toward a dynamical attractor where r_half ≈ r_max and σ ≈ 0.5 v_max, causing their inferred halo masses to follow narrow sequences based on size.
The Via Project is a planned five-year dual-hemisphere spectroscopic survey targeting over 2 million stars with 100 m/s RV stability and transient spectroscopy to r~24 using instruments on MMT and Magellan/Clay telescopes starting in 2027.
