Euclid: Field-level inference of primordial non-Gaussianity and cosmic initial conditions

A. Andrews, J. Jasche, G. Lavaux +147

A primary target of the \Euclid space mission is to constrain early-universe physics by searching for deviations from a primordial Gaussian random field. A significant detection of…

Euclid preparation: TBD. The impact of line-of-sight projections on the covariance between galaxy cluster multi-wavelength observable properties -- insights from hydrodynamic simulations

Euclid Collaboration, A. Ragagnin, A. Saro +240

Cluster cosmology can benefit from combining multi-wavelength studies, which can benefit from characterising the correlation coefficients between different mass-observable relation…

Euclid preparation: 6x2 pt analysis of Euclid's spectroscopic and photometric data sets

Euclid Collaboration, L. Paganin, M. Bonici +252

We present cosmological parameter forecasts for the Euclid 6x2pt statistics, which include the galaxy clustering and weak lensing main probes together with previously neglected cro…

Euclid preparation. Simulations and nonlinearities beyond CDM. 1. Numerical methods and validation

Euclid Collaboration, J. Adamek, B. Fiorini +268

To constrain models beyond CDM, the development of the Euclid analysis pipeline requires simulations that capture the nonlinear phenomenology of such models. We present an overv…

Euclid preparation. L. Calibration of the linear halo bias in CDM cosmologies

Euclid Collaboration, T. Castro, A. Fumagalli +253

The Euclid mission, designed to map the geometry of the dark Universe, presents an unprecedented opportunity for advancing our understanding of the cosmos through its photometric g…

Euclid preparation: Determining the weak lensing mass accuracy and precision for galaxy clusters

Euclid Collaboration, L. Ingoglia, M. Sereno +279

We investigate the level of accuracy and precision of cluster weak-lensing (WL) masses measured with the \Euclid data processing pipeline. We use the DEMNUni-Cov -body simulatio…
