Scale-Dependent Bias of Galaxies from Baryonic Acoustic Oscillations
  Baryonic acoustic oscillations (BAOs) modulate the density ratio of baryons
to dark matter across large regions of the Universe. We show that the
associated variation in the mass-to-light ratio of galaxies should generate an
oscillatory, scale-dependent bias of galaxies relative to the underlying
distribution of dark matter. A measurement of this effect would calibrate the
dependence of the characteristic mass-to-light ratio of galaxies on the baryon
mass fraction in their large scale environment. This bias, though, is unlikely
to significantly affect measurements of BAO peak positions.
