Accurate Predictions for the Scale-Dependent Galaxy Bias from Primordial
  Non-Gaussianity
  The large-scale clustering of galaxies can serve as a probe of primordial
non-Gaussianity in the Universe competitive with the anisotropies of the CMB.
Here, we present improved theoretical predictions which include an important,
previously overlooked correction to the bias. We demonstrate that the new
predictions are able to reproduce the results of N-body simulations, explaining
the significant departures seen from previous theoretical results. These
refined predictions open the way to accurate constraints on primordial physics
with large-scale structure surveys.
