Abstract

En 中文

We apply the Effective Field Theory of Large-Scale Structure to analyze the wCDM cosmological model. By using the full shape of the power spectrum and the BAO post-reconstruction measurements from BOSS, the Supernovae from Pantheon, and a prior from BBN, we set the competitive CMB-independent limit w = -1.0461(-0.052)(+0.055) at 68% C.L. After adding the Planck CMB data, we find w = -1.023(-0.030)(+0.033) at 68% C.L. Our results are obtained using PyBird, a new, fast Python-based code which we make publicly available.
