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…
Machine learning applied to simulations of collisions between rotating, differentiated planets
Miles Timpe, Maria Han Veiga, Mischa Knabenhans +2
In the late stages of terrestrial planet formation, pairwise collisions between planetary-sized bodies act as the fundamental agent of planet growth. These collisions can lead to e…
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…
