Large-Scale Structure Formation with Massive Neutrinos and Dynamical Dark Energy

Understand

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.
