Dark Energy Survey Year 3 Results: Calibration of Lens Sample Redshift Distributions using Clustering Redshifts with BOSS/eBOSS

R. Cawthon, J. Elvin-Poole, A. Porredon +83

We present clustering redshift measurements for Dark Energy Survey (DES) lens sample galaxies to be used in weak gravitational lensing and galaxy clustering studies. To perform thi…

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…

DES Y3 results: Blending shear and redshift biases in image simulations

N. MacCrann, M. R. Becker, J. McCullough +93

As the statistical power of galaxy weak lensing reaches percent level precision, large, realistic and robust simulations are required to calibrate observational systematics, especi…

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…

Constraints on dark matter to dark radiation conversion in the late universe with DES-Y1 and external data

Angela Chen, Dragan Huterer, Sujeong Lee +81

We study a phenomenological class of models where dark matter converts to dark radiation in the low redshift epoch. This class of models, dubbed DMDR, characterizes the evolution o…

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…

Dark Energy Survey Year 1 Results: Cosmological Constraints from Cluster Abundances, Weak Lensing, and Galaxy Correlations

C. To, E. Krause, E. Rozo +105

Combining multiple observational probes is a powerful technique to provide robust and precise constraints on cosmological parameters. In this letter, we present the first joint ana…

DES Y1 results: Splitting growth and geometry to test CDM

J. Muir, E. Baxter, V. Miranda +100

We analyze Dark Energy Survey (DES) data to constrain a cosmological model where a subset of parameters -- focusing on -- are split into versions associated with structure gr…

Cosmology Intertwined IV: The Age of the Universe and its Curvature

Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +88

A precise measurement of the curvature of the Universe is of primeval importance for cosmology since it could not only confirm the paradigm of primordial inflation but also help in…

Cosmology Intertwined III: and

Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +89

The standard Cold Dark Matter cosmological model provides a wonderful fit to current cosmological data, but a few tensions and anomalies became statistically significant with t…

Cosmology Intertwined I: Perspectives for the Next Decade

Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +89

The standard Cold Dark Matter cosmological model provides an amazing description of a wide range of astrophysical and astronomical data. However, there are a few big open quest…
