Euclid: Constraining linearly scale-independent modifications of gravity with the spectroscopic and photometric primary probes

Noemi Frusciante, +128 more
TL;DR: In this paper , the authors focus on modified gravity models characterised, at linear scales, by a scale-independent growth of perturbations while featuring different testable types of derivative screening mechanisms at smaller nonlinear scales.
Journal ArticleDOI

Euclid preparation. XXIV. Calibration of the halo mass function in $\Lambda(\nu)$CDM cosmologies

Euclid Collaboration T. Castro, +180 more
TL;DR: In this paper , a new calibration of the analytic halo mass function (HMF) is presented, at the level of accuracy and precision required for the uncertainty in this quantity to be subdominant with respect to other sources of uncertainty in recovering cosmological parameters from Euclid cluster counts.

The Euclid Archive System: A Data-Centric Approach to Big Data

TL;DR: The Euclid Archive System (EAS) as discussed by the authors is a data-centric scientific information system, which is in the core of the Euclid Science Ground System (SGS).
Journal ArticleDOI

Leveraging Data Lineage to Infer Logical Relationships between Astronomical Catalogs

TL;DR: In this paper, a method to infer logical relationships between sets is presented, which does not require the contents of the sets to be known explicitly and combines incomplete knowledge about the relationships among sets to infer a priori unknown relationships.

Euclid: Validation of the MontePython forecasting tools

S. Casas, +442 more
TL;DR: In this article , the authors extend and adjust the mock Euclid likelihoods of the MontePython software in order to match the exact recipes used in previous Euclid Fisher matrix forecasts for several probes: weak lensing cosmic shear, photometric galaxy clustering, the cross-correlation between the latter observables, and spectroscopic galaxy clusters.
