Euclid preparation LX. The use of HST images as input for weak-lensing image simulations

Euclid Collaboration, D. Scognamiglio, T. Schrabback +245

Data from the Euclid space telescope will enable cosmic shear measurements with very small statistical errors, requiring corresponding systematic error control level. A common appr…

Euclid preparation: TBD. The impact of line-of-sight projections on the covariance between galaxy cluster multi-wavelength observable properties -- insights from hydrodynamic simulations

Euclid Collaboration, A. Ragagnin, A. Saro +240

Cluster cosmology can benefit from combining multi-wavelength studies, which can benefit from characterising the correlation coefficients between different mass-observable relation…

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 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…

Euclid preparation LXIII. Simulations and nonlinearities beyond CDM. 2. Results from non-standard simulations

Euclid Collaboration, G. Rácz, M. -A. Breton +275

The Euclid mission will measure cosmological parameters with unprecedented precision. To distinguish between cosmological models, it is essential to generate realistic mock observa…
