Euclid preparation
Astronomy and Astrophysics, vol. 713, pp. A186
Abstract
As the statistical precision of cosmological measurements increases, the accuracy of the theoretical description of these measurements must correspondingly increase to infer the underlying cosmology governing the Universe. To this end, we created the Cosmology Likelihood for Observables in Euclid (CLOE), which is a novel cosmological parameter inference pipeline developed within the Euclid Consortium to translate measurements and covariances into cosmological parameter constraints. In this first in a series of five papers, we describe the theoretical recipe of this code for the Euclid primary probes. These probes are composed of the photometric 3 × 2pt observables of cosmic shear, galaxy-galaxy lensing, and galaxy clustering, along with spectroscopic galaxy clustering. We provide this description in both Fourier and configuration space for standard and extended summary statistics, including the wide range of systematic uncertainties that affect these statistics. This includes systematic uncertainties such as intrinsic galaxy alignments, baryonic feedback, photometric and spectroscopic redshift uncertainties, shear calibration uncertainties, sample impurities, photometric and spectroscopic galaxy biases, as well as magnification bias. The theoretical descriptions can further accommodate both Gaussian and non-Gaussian likelihoods, as well as extended cosmologies with non-zero curvature, massive neutrinos, evolving dark energy, and simple forms of modified gravity. These theoretical descriptions that underpin CLOE will form a crucial component in revealing the true nature of the Universe with next-generation cosmological surveys such as Euclid .
