GD-1 and the Milky Way Starless Dark Matter Subhalos
Measurements of the GD-1 star stream velocity distribution within ±3° of the centerline find a total line-of-sight velocity spread of 5–6 km s ^−1 in the-well measured ϕ _1 = [−30, 0] region. The velocity spread is far above the ∼2–3 km s ^−1 of a dissolved globular cluster in a smooth galactic pot...
