Assessing tension metrics with Dark Energy Survey and Planck data

P. Lemos, M. Raveri, A. Campos +103

Quantifying tensions -- inconsistencies amongst measurements of cosmological parameters by different experiments -- has emerged as a crucial part of modern cosmological data analys…

Dark Energy Survey Year 3 Results: Covariance Modelling and its Impact on Parameter Estimation and Quality of Fit

O. Friedrich, F. Andrade-Oliveira, H. Camacho +109

We describe and test the fiducial covariance matrix model for the combined 2-point function analysis of the Dark Energy Survey Year 3 (DES-Y3) dataset. Using a variety of new ansat…

Dark Energy Survey Year 3 Results: Redshift Calibration of the Weak Lensing Source Galaxies

J. Myles, A. Alarcon, A. Amon +105

Determining the distribution of redshifts of galaxies observed by wide-field photometric experiments like the Dark Energy Survey is an essential component to mapping the matter den…

Consistency of cosmic shear analyses in harmonic and real space

C. Doux, C. Chang, B. Jain +67

Recent cosmic shear studies have reported discrepancies of up to on the parameter between the analysis of shear power spectra and two-point…

Dark Energy Survey Year 3 Results: Optimizing the Lens Sample in Combined Galaxy Clustering and Galaxy-Galaxy Lensing Analysis

A. Porredon, M. Crocce, P. Fosalba +77

We investigate potential gains in cosmological constraints from the combination of galaxy clustering and galaxy-galaxy lensing by optimizing the lens galaxy sample selection using…

Dark Energy Survey internal consistency tests of the joint cosmological probes analysis with posterior predictive distributions

C. Doux, E. Baxter, P. Lemos +85

Beyond-CDM physics or systematic errors may cause subsets of a cosmological data set to appear inconsistent when analyzed assuming CDM. We present an application of internal…
