Contributions from primordial non-Gaussianity and General Relativity to
  the galaxy power spectrum
  We compute the real space galaxy power spectrum, including the leading order
effects of General Relativity and primordial non-Gaussianity from the
$f_{\mathrm{NL}}$ and $g_{\mathrm{NL}}$ parameters. Such contributions come
from the one-loop matter power spectrum terms dominant at large scales, and
from the factors of the non-linear bias parameter $b_{\mathrm{NL}}$ (akin to
the Newtonian $b_{\phi}$). We assess the detectability of these contributions
in Stage-IV surveys. In particular, we note that specific values of the bias
parameter may erase the primordial and relativistic contributions to the
configuration space power spectrum.
