MOND Predictions

• The Tully-Fisher Relation
  • Slope = 4
  • Normalization = (a₀G)^-1
  • Fundamentally a relation between Disk Mass and V_flat
  • No Dependence on Surface Brightness

• Dependence of conventional M/L on radius and surface brightness

• Rotation Curve Shapes

• Surface Density ~ Surface Brightness

• Detailed Rotation Curve Fits

• Stellar Population Mass-to-Light Ratios

What's an humble observer suppose to conclude?
