UNIONS-3500 Weak Lensing: IV. 2D cosmological constraints in harmonic space
S. Guerrini, L. W. K. Goh, F. Hervas-Peters +14
The Ultraviolet Near Infrared Optical Northern Survey (UNIONS) is a photometric survey in the northern sky. The quality of the data in the band provides precise shape measureme…
UNIONS-3500 Weak Lensing: I. A Galaxy Shape Catalogue in the Northern Sky
F. Hervas-Peters, S. Guerrini, M. Kilbinger +15
Weak gravitational lensing has become a widely used effect to characterise the dark-matter distribution on large scales in the Universe by measuring galaxy ellipticities and their…
UNIONS-3500 Weak Lensing: III. 2D Cosmological Constraints in Configuration Space
L. W. K. Goh, S. Guerrini, C. Daley +13
We present the first cosmological constraints from the cosmic shear analysis of the UNIONS-3500 weak lensing galaxy catalogue in configuration space. The Ultraviolet Near Infrared…
Euclid preparation. CosmoPostProcess: A simulation calibrated framework for weak lensing selection bias in richness-selected galaxy clusters
Euclid Collaboration, R. Ingrao, M. Costanzi +280
We present \texttt{CosmoPostProcess}, a simulation-based forward-modelling algorithm calibrated to reproduce Euclid optical cluster observables. Its main deliverable is a correctio…
UNIONS-3500 Weak Lensing: II. B-mode validation for cosmic shear
C. Daley, A. Guinot, S. Guerrini +9
At Stage-III sensitivities, cosmic shear modes unambiguously indicate systematic contamination and are often used to inform data selection and scale cuts for cosmological infer…
Euclid preparation. XCVI. Cosmology Likelihood for Observables in Euclid (CLOE). 3. Inference and Forecasts
Euclid Collaboration, G. Cañas-Herrera, L. W. K. Goh +337
The Euclid mission aims to measure the positions, shapes, and redshifts of over a billion galaxies to provide unprecedented constraints on the nature of dark matter and dark energy…
Euclid preparation. XCI. Validation method for the detections in the Euclid Catalogue of Galaxy Clusters using external data
Euclid Collaboration, J. -B. Melin, S. A. Stanford +315
We present our methodology for identifying known clusters as counterparts to objects in the Euclid Catalogue of Galaxy Clusters (ECGC). Euclid is expected to detect a large number…
Euclid preparation. Constraining parameterised models of modifications of gravity with the spectroscopic and photometric primary probes
Euclid Collaboration, I. S. Albuquerque, N. Frusciante +285
The Euclid mission has the potential to understand the fundamental physical nature of late-time cosmic acceleration and, as such, of deviations from the standard cosmological model…
Euclid preparation. 3-dimensional galaxy clustering in configuration space. Part I. 2-point correlation function estimation
Euclid Collaboration, S. de la Torre, F. Marulli +297
The 2-point correlation function of the galaxy spatial distribution is a major cosmological observable that enables constraints on the dynamics and geometry of the Universe. The Eu…
Euclid preparation LXXI. Simulations and nonlinearities beyond CDM. 3. Constraints on models from the photometric primary probes
Euclid Collaboration, K. Koyama, S. Pamuk +275
We study the constraint on gravity that can be obtained by photometric primary probes of the Euclid mission. Our focus is the dependence of the constraint on the theoretical…
Euclid preparation: Determining the weak lensing mass accuracy and precision for galaxy clusters
Euclid Collaboration, L. Ingoglia, M. Sereno +279
We investigate the level of accuracy and precision of cluster weak-lensing (WL) masses measured with the \Euclid data processing pipeline. We use the DEMNUni-Cov -body simulatio…
Euclid preparation. LIX. Angular power spectra from discrete observations
Euclid Collaboration, N. Tessore, B. Joachimi +266
We present the framework for measuring angular power spectra in the Euclid mission. The observables in galaxy surveys, such as galaxy clustering and cosmic shear, are not continuou…
Euclid. V. The Flagship galaxy mock catalogue: a comprehensive simulation for the Euclid mission
Euclid Collaboration, F. J. Castander, P. Fosalba +366
We present the Flagship galaxy mock, a simulated catalogue of billions of galaxies designed to support the scientific exploitation of the Euclid mission. Euclid is a medium-class m…
