Query: Large-Scale Structure Formation with Massive Neutrinos and Dynamical
  Dark Energy   Over the next decade, cosmological measurements of the large-scale structure
of the Universe will be sensitive to the combined effects of dynamical dark
energy and massive neutrinos. The matter power spectrum is a key repository of
this information. We extend higher-order perturbative methods for computing the
power spectrum to investigate these effects over quasi-linear scales. Through
comparison with N-body simulations we establish the regime of validity of a
Time-Renormalization Group (Time-RG) perturbative treatment that includes
dynamical dark energy and massive neutrinos. We also quantify the accuracy of
Standard (SPT), Renormalized (RPT) and Lagrangian Resummation (LPT)
perturbation theories without massive neutrinos. We find that an approximation
that neglects neutrino clustering as a source for nonlinear matter clustering
predicts the Baryon Acoustic Oscillation (BAO) peak position to 0.25% accuracy
for redshifts 1 < z < 3, justifying the use of LPT for BAO reconstruction in
upcoming surveys. We release a modified version of the public Copter code which
includes the additional physics discussed in the paper.
