Dark Energy Survey Year 6 Results: fast and interpretable posterior predictive checks for correlated cosmic probes
C. Doux, J. Muir, A. Ferté +59
We present a fast and numerically stable framework for conducting posterior predictive distribution (PPD) tests of internal consistency in correlated cosmological probes. Our metho…
Dark Energy Survey Year 6 Results: Cosmological Constraints from Cosmic Shear
DES Collaboration, T. M. C. Abbott, M. Aguena +126
We present legacy cosmic shear measurements and cosmological constraints using six years of Dark Energy Survey imaging data. From these data, we study ~140 million galaxies (8.29 g…
Dark Energy Survey Year 6 Results: Cosmological Constraints from Galaxy Clustering and Weak Lensing
DES Collaboration, T. M. C. Abbott, M. Adamow +169
We present cosmology results combining galaxy clustering and weak gravitational lensing measured in the full six years (Y6) of observations by the Dark Energy Survey (DES) covering…
Dark Energy Survey Year 6 Results: Weak Lensing and Galaxy Clustering Cosmological Analysis Framework
D. Sanchez-Cid, A. Ferté, J. Blazek +115
We present the methodology for the weak lensing and galaxy clustering analyses of the Dark Energy Survey (DES) Year 6 data set. In this work, we design and validate the analysis pi…
Prospects for disentangling dark matter with weak lensing
Calvin Preston, Keir K. Rogers, Alexandra Amon +1
We investigate the degeneracy between the effects of ultra-light axion dark matter and baryonic feedback in suppressing the matter power spectrum. We forecast that galaxy shear dat…
Reconstructing the matter power spectrum with future cosmic shear surveys
Calvin Preston, Alexandra Amon, George Efstathiou
Analyses of cosmic shear typically condense weak lensing information over a range of scales to a single cosmological parameter, . This paper presents a method to extract more…
Weak lensing combined with the kinetic Sunyaev Zel'dovich effect: A study of baryonic feedback
L. Bigwood, A. Amon, A. Schneider +122
Extracting precise cosmology from weak lensing surveys requires modelling the non-linear matter power spectrum, which is suppressed at small scales due to baryonic feedback process…
A non-linear solution to the tension II: Analysis of DES Year 3 cosmic shear
Calvin Preston, Alexandra Amon, George Efstathiou
Weak galaxy lensing surveys have consistently reported low values of the parameter compared to the cosmology. Amon & Efstathiou (2022) used KiDS-…
