Euclid : Forecasts on Lambda cold dark matter consistency tests with growth rate data
Astronomy and Astrophysics, vol. 714, pp. A57
Abstract
The large-scale structure (LSS) of the Universe is an important probe for deviations from the canonical cosmological constant Λ and cold dark matter (ΛCDM) model. A statistically significant detection of any deviations would signify the presence of a new physics or the breakdown of any number of the underlying assumptions of the standard cosmological model or possible systematic errors in the data. In this paper, we quantify the ability of the LSS data products of the spectroscopic survey of the Euclid mission, together with other contemporary surveys, to improve the constraints on deviations from ΛCDM in the redshift range 0 < z < 1.75. We consider both currently available growth rate data and simulated data with specifications from Euclid and external surveys, based on ΛCDM and a modified gravity (MoG) model with an evolving Newton’s constant (denoted μCDM), and carry out a binning method and a machine learning reconstruction, based on genetic algorithms (GAs), of several LSS null tests. Using the forecast Euclid growth data from the spectroscopic survey in the range 0.95 < z < 1.75, we find that in combination with external data products (covering the range 0 < z < 0.95), Euclid will be able to improve the precision of current null tests of the LSS on average by a factor of eight when using a binning method and a factor of six when using the GAs. Our work highlights the need for synergies between Euclid and other surveys, but also the usefulness of statistical analyses, such as GAs, in order to disentangle any degeneracies in the cosmological parameters. Both are necessary to provide tight constraints over an extended redshift range and to probe for deviations from the ΛCDM model.
