Euclid preparation: VI. Verifying the Performance of Cosmic Shear Experiments
Euclid Collaboration, P. Paykari, T. D. Kitching +128
Our aim is to quantify the impact of systematic effects on the inference of cosmological parameters from cosmic shear. We present an end-to-end approach that introduces sources of…
Strong Lensing Time Delay Constraints on Dark Energy: a Forecast
Banafshe Shiralilou, Matteo Martinelli, Georgios Papadomanolakis +3
Measurements of time delays between multiple quasar images produced by strong lensing are reaching a sensitivity that makes them a promising cosmological probe. Future surveys will…
Euclid preparation: VII. Forecast validation for Euclid cosmological probes
Euclid Collaboration, A. Blanchard, S. Camera +151
The Euclid space telescope will measure the shapes and redshifts of galaxies to reconstruct the expansion history of the Universe and the growth of cosmic structures. Estimation of…
CMB tensions with low-redshift and measurements: impact of a redshift-dependent type-Ia supernovae intrinsic luminosity
Matteo Martinelli, Isaac Tutusaus
With the recent increase in precision of our cosmological datasets, measurements of CDM model parameter provided by high- and low-redshift observations started to be in tension,…
Constraints on the interacting vacuum -- geodesic CDM scenario
Matteo Martinelli, Natalie B. Hogg, Simone Peirone +2
We investigate an interacting dark sector scenario in which the vacuum energy is free to interact with cold dark matter (CDM), which itself is assumed to cluster under the sole act…
Reconstruction of the Dark Energy equation of state from latest data: the impact of theoretical priors
Francesca Gerardi, Matteo Martinelli, Alessandra Silvestri
We reconstruct the Equation of State of Dark Energy (EoS) from current data using a non-parametric approach where, rather than assuming a specific time evolution of this function,…
