Inflation without an Inflaton

Daniele Bertacca, Raul Jimenez, Sabino Matarrese +1

We propose a novel scenario in which scalar perturbations, that seed the large scale structure of the Universe, are generated without relying on a scalar field (the inflaton). In t…

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…

Gravitational wave luminosity distance-weighted anisotropies

A. Begnoni, L. Valbusa Dall'Armi, D. Bertacca +1

Measurements of the luminosity distance of propagating gravitational waves can provide invaluable information on the geometry and content of our Universe. Due to the clustering of…

Euclid preparation. The impact of relativistic redshift-space distortions on two-point clustering statistics from the Euclid wide spectroscopic survey

Euclid Collaboration, M. Y. Elkhashab, D. Bertacca +252

Measurements of galaxy clustering are affected by RSD. Peculiar velocities, gravitational lensing, and other light-cone projection effects modify the observed redshifts, fluxes, an…

Euclid. I. Overview of the Euclid mission

Euclid Collaboration, Y. Mellier, Abdurro'uf +1134

The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…

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…
