Upper panles: Baryonic impact on the matter power spectrum at z = 0, defined as S(k) = PHydro/PGro, as measaured in hydrodynamical simulations. The solid line represents the best-fitting models otained with our emulator. Lower panels: ratio between hydrodynamical simulations and our model, considering 7, 3, and 1 free parameters
Abstract
BACCOemu provides a collection of emulators for large-scale structure statistics over a wide range of cosmologies. The emulators provide fast predictions for the linear cold- and total-matter power spectrum, the nonlinear cold-matter power spectrum, and the modifications to the cold-matter power spectrum caused by baryonic physics in a wide cosmological parameter space, including dynamical dark energy and massive neutrinos.
