Euclid: Forecasts for -cut Point Statistics
P. L. Taylor, T. Kitching, V. F. Cardone +92
Modelling uncertainties at small scales, i.e. high in the power spectrum , due to baryonic feedback, nonlinear structure growth and the fact that galaxies are biased trac…
Multi-CCD Point Spread Function Modelling
T. Liaudat, J. Bonnin, J. -L. Starck +4
Galaxy imaging surveys observe a vast number of objects that are affected by the instrument's Point Spread Function (PSF). Weak lensing missions, in particular, aim at measuring th…
Euclid: impact of nonlinear prescriptions on cosmological parameter estimation from weak lensing cosmic shear
M. Martinelli, I. Tutusaus, M. Archidiacono +91
Upcoming surveys will map the growth of large-scale structure with unprecented precision, improving our understanding of the dark sector of the Universe. Unfortunately, much of the…
Euclid preparation: X. The Euclid photometric-redshift challenge
Euclid Collaboration, G. Desprez, S. Paltani +170
Forthcoming large photometric surveys for cosmology require precise and accurate photometric redshift (photo-z) measurements for the success of their main science objectives. Howev…
Euclid preparation: VIII. The Complete Calibration of the Colour-Redshift Relation survey: VLT/KMOS observations and data release
Euclid Collaboration, V. Guglielmo, R. Saglia +145
The Complete Calibration of the Colour-Redshift Relation survey (C3R2) is a spectroscopic effort involving ESO and Keck facilities designed to empirically calibrate the galaxy colo…
Euclid: Forecast constraints on the cosmic distance duality relation with complementary external probes
M. Martinelli, C. J. A. P. Martins, S. Nesseris +82
In metric theories of gravity with photon number conservation, the luminosity and angular diameter distances are related via the Etherington relation, also known as the distance-du…
