THE DISKMASS SURVEY. IV. THE DARK-MATTER-DOMINATED GALAXY UGC 463
We present a detailed and unique mass budget for the high-surface-brightness galaxy UGC 463, showing it is dominated by dark matter (DM) at radii beyond one scale length (h_R) and has a baryonic-to-DM mass ratio of approximately 1:3 within 4.2 h_R. Assuming a constant scale height (h_z, calculated via an …
