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 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: Galaxy-galaxy lensing

G. Giannini, G. Camacho-Ciurana, A. Whyley +116

We present galaxy--galaxy lensing (GGL) measurements from the full six years of data from the Dark Energy Survey (DES Y6), covering and used in the DES Y6 $3…

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…

Dark Energy Survey Year 6 Results: Magnification modeling and its impact on galaxy clustering and galaxy-galaxy lensing cosmology

E. Legnani, J. Elvin-Poole, D. Anbajagane +72

Gravitational lensing magnification alters the observed spatial distribution of galaxies and must be accounted for to prevent biases in cosmological probes of the large-scale struc…

Confronting cosmic shear astrophysical uncertainties: DES Year 3 revisited

Leah Bigwood, Jamie McCullough, Jared Siegel +19

Cosmology from weak gravitational lensing has been limited by astrophysical uncertainties in baryonic feedback and intrinsic alignments. By calibrating these effects using external…

Dark Energy Survey Year 6 Results: Clustering-redshifts and importance sampling of Self-Organised-Maps realizations for pt samples

W. d'Assignies, G. M. Bernstein, B. Yin +92

This work is part of a series establishing the redshift framework for the pt analysis of the Dark Energy Survey Year 6 (DES Y6). For DES Y6, photometric redshift distribu…

Dark Energy Survey Year 6 Results: Synthetic-source Injection Across the Full Survey Using Balrog

D. Anbajagane, M. Tabbutt, J. Beas-Gonzalez +79

Synthetic source injection (SSI), the insertion of sources into pixel-level on-sky images, is a powerful method for characterizing object detection and measurement in wide-field, a…

Dark Energy Survey Year 3: Blue Shear

J. McCullough, A. Amon, E. Legnani +115

Modeling the intrinsic alignment (IA) of galaxies poses a challenge to weak lensing analyses. The Dark Energy Survey is expected to be less impacted by IA when limited to blue, sta…

The IA Guide: A Breakdown of Intrinsic Alignment Formalisms

Claire Lamman, Eleni Tsaprazi, Jingjing Shi +4

We summarize common notations and concepts in the field of Intrinsic Alignments (IA). IA refers to physical correlations involving galaxy shapes, galaxy spins, and the underlying c…
