Parameter inference with non-linear galaxy clustering: accounting for theoretical uncertainties
Mischa Knabenhans, Thejs Brinckmann, Joachim Stadel +2
We implement EuclidEmulator (version 1), an emulator for the non-linear correction of the matter power spectrum, into the MCMC forecasting code MontePython. We compare the performa…
Baryonic effects for weak lensing. Part II. Combination with X-ray data and extended cosmologies
Aurel Schneider, Alexandre Refregier, Sebastian Grandis +6
An accurate modelling of baryonic feedback effects is required to exploit the full potential of future weak-lensing surveys such as Euclid or LSST. In this second paper in a series…
Baryonic effects for weak lensing. Part I. Power spectrum and covariance matrix
Aurel Schneider, Nicola Stoira, Alexandre Refregier +4
Baryonic feedback effects lead to a suppression of the weak lensing angular power spectrum on small scales. The poorly constrained shape and amplitude of this suppression is an imp…
Dark energy perturbations in -body simulations
Jeppe Dakin, Steen Hannestad, Thomas Tram +2
We present -body simulations which are fully compatible with general relativity, with dark energy consistently included at both the background and perturbation level. We test ou…
Euclid preparation: II. The EuclidEmulator -- A tool to compute the cosmology dependence of the nonlinear matter power spectrum
Euclid Collaboration, Mischa Knabenhans, Joachim Stadel +12
We present a new power spectrum emulator named EuclidEmulator that estimates the nonlinear correction to the linear dark matter power spectrum. It is based on a spectral decomposit…
