Evidence for Sub-Maximal Disks • Bottema (1997): stellar kinematics of galactic disks • Predicted by analytical models of galaxy formation (e.g. Mo, Mao, & White 1998). Assumes AC. • <strong>Courteau</strong> & Rix (1999), <strong>Courteau</strong> etal (2005): TF residuals Assumes AC. • Kregel et al. (2002): disk flattening of edge-on galaxies • Trott & Webster (2002): lensing + rotation curve constraints • Dutton et al. (2005): mass modeling with stellar population constraints, including barred galaxies. Assumes AC. V disk /V tot ≤ 0.6 M DM /M tot ≥ 0.7 (on average at 2.2 disk scale lengths)
Evidence for Maximal (Bright and Barred) Disks • Weiner (2002), Perez (2003): fluid models applied to streaming motions in barred galaxies • Slyz, Kranz & Rix (2003): gas kinematics and structure of spiral arms -- range of dark matter content with SB • N-body simulations: resonance issues related to bar-halo friction • What can we do to move forward? HSB galaxies could be light dominated while LSB galaxies are DM-dominated at 2 disk scale lengths.
