The internal kinematics of the Leo I dwarf spheroidal galaxy: dark matter at the fringe of the Milky Way.
MATEO M., OLSZEWSKI E.W., VOGT S.S. and KEANE M.J.
Abstract (from CDS):
Because Leo I is isolated and has passed the Milky Way at most once in the past, external tides could not plausibly have inflated its central dispersion to the observed value. We also considered whether modified Newtonian dynamics (MOND) could account for the internal kinematics of Leo I and conclude that this alternative gravitational model can account for the Leo I kinematics adequately without requiring a dark halo.
