Mitigating Nonlinear Systematics in Weak Lensing Surveys II: Stability and Diagnostics with Intrinsic Alignment
Shiming Gu, Ludovic van Waerbeke, Francis Bernardeau +1
The Bernardeau-Nishimichi-Taruya (BNT) transform provides a powerful framework for analysing tomographic cosmic shear data by improving the localization of shear correlations in ph…
The Domain Adaptation problem in photometric redshift estimation: a solution applied to the HSC Survey
M. Treyer, R. Ait-Ouahmed, S. Arnouts +5
The multi-band HSC-CLAUDS survey comprises several sky regions with varying observing conditions, only one of which, the COSMOS Ultra Deep Field (UDF), offers extensive redshift co…
Euclid preparation. Review of forecast constraints on dark energy and modified gravity
Euclid Collaboration, N. Frusciante, M. Martinelli +326
The Euclid mission has been designed to provide, as one of its main deliverables, information on the nature of the gravitational interaction, which determines the expansion of the…
Growth rate measurements from a joint analysis of the large-scale galaxy clustering in Fourier and configuration space
Vincenzo Aronica, Julian E. Bautista, Arnaud de Mattia +1
In this work, we test a framework to perform the analysis of redshift-space distortions simultaneously in configuration and Fourier space. We test our methods with the AbacusSummit…
Constraining primordial non-Gaussianity from DESI DR1 quasars and Planck PR4 CMB Lensing
Sofia Chiarenza, Alex Krolewski, Marco Bonici +54
We present the first measurement of local-type primordial non-Gaussianity from the cross-correlation between million spectroscopically confirmed quasars from the first data r…
The DESI DR1 Peculiar Velocity Survey: Fundamental Plane Catalogue
C. E. Ross, C. Howlett, J. R. Lucey +58
Measurements of peculiar velocities in the local Universe are a powerful tool to study the nature of dark energy at low () redshifts. Here we present the largest single se…
