1301.0822 (Stacy McGaugh et al.)

Andromeda Dwarfs in Light of MOND    [PDF]

Stacy McGaugh, Mordehai Milgrom
We compare the recently published velocity dispersions for seventeen Andromeda dwarf spheroidals with estimates of the MOND predictions, based on the luminosities of these dwarfs, with reasonable stellar M/L values, and no dark matter. We find that the two are consistent within the uncertainties. We further predict the velocity dispersions of another nine dwarfs for which only photometric data are currently available. A comparably direct prediction cannot be made in the context LCDM.
