Euclid: constraining dark energy coupled to electromagnetism using astrophysical and laboratory data
M. Martinelli, C. J. A. P. Martins, S. Nesseris +92
In physically realistic scalar-field based dynamical dark energy models (including, e.g., quintessence) one naturally expects the scalar field to couple to the rest of the model's…
Euclid: Estimation of the impact of correlated readout noise for flux measurements with the Euclid NISP instrument
A. Jimenez Munoz, J. Macias-Perez, A. Secroun +96
The Euclid satellite, to be launched by ESA in 2022, will be a major instrument for cosmology for the next decades. \Euclid\ is composed of two instruments: the Visible (VIS) instr…
Euclid: Effect of sample covariance on the number counts of galaxy clusters
A. Fumagalli, A. Saro, S. Borgani +93
Aims. We investigate the contribution of shot-noise and sample variance to the uncertainty of cosmological parameter constraints inferred from cluster number counts in the context…
Euclid preparation: XI. Mean redshift determination from galaxy redshift probabilities for cosmic shear tomography
Euclid Collaboration, O. Ilbert, S. de la Torre +162
The analysis of weak gravitational lensing in wide-field imaging surveys is considered to be a major cosmological probe of dark energy. Our capacity to constrain the dark energy eq…
