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.
