Galactic rotation curves in Einstein's conformal gravity
  We show quantitatively that an exact solution of Einstein's conformal gravity
can explain very well the galactic rotation curves for a sample of 104 galaxies
without need for dark matter or other exotic modification of gravity. The
metric is an overall rescaling of the Schwarzschild-de Sitter spacetime as
required by Weyl conformal invariance, which has to be spontaneously broken,
and the velocity of the stars depends only on two universal parameters
determined on the base of the observational data.
