Euclid preparation. The shape of halo profiles in CDM and non-standard cosmologies

Euclid Collaboration, L. Pizzuti, G. Y. Ferron +304

We study the shape of three-dimensional and projected dark-matter halo profiles extracted from cosmological -body simulations in CDM and non-standard cosmologies, using the \…

Empirical signatures of velocity and density cascades in the Local Universe probed by the CosmicFlows4 dataset

Yves Grosdidier, Hélène M. Courtois

Aims: Our aim is to characterise the multiscale statistical properties of the reconstructed velocity and density fields of the nearby Universe, identify possible scaling regimes, q…

Euclid preparation. XCVIII. Cosmology Likelihood for Observables in Euclid (CLOE). 5: Extensions beyond the standard modelling of theoretical probes and systematic effects

Euclid Collaboration, L. W. K. Goh, A. Nouri-Zonoz +301

Euclid is expected to establish new state-of-the-art constraints on extensions beyond the standard LCDM cosmological model by measuring the positions and shapes of billions of gala…

Euclid preparation. XXXI. The effect of the variations in photometric passbands on photometric-redshift accuracy

Euclid Collaboration, Stéphane Paltani, J. Coupon +214

The technique of photometric redshifts has become essential for the exploitation of multi-band extragalactic surveys. While the requirements on photo-zs for the study of galaxy evo…

Euclid preparation. LII. Forecast impact of super-sample covariance on 3x2pt analysis with Euclid

Euclid Collaboration, D. Sciotti, S. Gouyou Beauchamps +221

Deviations from Gaussianity in the distribution of the fields probed by large-scale structure surveys generate additional terms in the data covariance matrix, increasing the uncert…

Euclid: The search for primordial features

M. Ballardini, Y. Akrami, F. Finelli +126

Primordial features, in particular oscillatory signals, imprinted in the primordial power spectrum of density perturbations represent a clear window of opportunity for detecting ne…
