The DES view of the Eridanus supervoid and the CMB Cold Spot
A. Kovács, N. Jeffrey, M. Gatti +119
The Cold Spot is a puzzling large-scale feature in the Cosmic Microwave Background temperature maps and its origin has been subject to active debate. As an important foreground str…
SkyPy: A package for modelling the Universe
Adam Amara, Lucia F. de la Bella, Simon Birrer +18
SkyPy is an open-source Python package for simulating the astrophysical sky. It comprises a library of physical and empirical models across a range of observables and a command-lin…
Dark Energy Survey Year 3 results: Marginalisation over redshift distribution uncertainties using ranking of discrete realisations
Juan P. Cordero, Ian Harrison, Richard P. Rollins +92
Cosmological information from weak lensing surveys is maximised by dividing source galaxies into tomographic sub-samples for which the redshift distributions are estimated. Uncerta…
Dark Energy Survey Year 3 results: Galaxy-halo connection from galaxy-galaxy lensing
G. Zacharegkas, C. Chang, J. Prat +114
Galaxy-galaxy lensing is a powerful probe of the connection between galaxies and their host dark matter halos, which is important both for galaxy evolution and cosmology. We extend…
Dark Energy Survey Year 3 results: cosmology from combined galaxy clustering and lensing -- validation on cosmological simulations
J. DeRose, R. H. Wechsler, M. R. Becker +114
We present a validation of the Dark Energy Survey Year 3 (DES Y3) -point analysis choices by testing them on Buzzard v2.0, a new suite of cosmological simulations that is…
Dark Energy Survey Year 3 Results: Cosmological Constraints from Galaxy Clustering and Weak Lensing
DES Collaboration, T. M. C. Abbott, M. Aguena +168
We present the first cosmology results from large-scale structure in the Dark Energy Survey (DES) spanning 5000 deg. We perform an analysis combining three two-point correlatio…
Dark Energy Survey Year 3 results: Cosmological constraints from galaxy clustering and galaxy-galaxy lensing using the MagLim lens sample
A. Porredon, M. Crocce, J. Elvin-Poole +141
Two of the most sensitive probes of the large scale structure of the universe are the clustering of galaxies and the tangential shear of background galaxy shapes produced by those…
Dark Energy Survey Year 3 Results: Cosmology from Cosmic Shear and Robustness to Modeling Uncertainty
L. F. Secco, S. Samuroff, E. Krause +151
This work and its companion paper, Amon et al. (2021), present cosmic shear measurements and cosmological constraints from over 100 million source galaxies in the Dark Energy Surve…
Dark Energy Survey Year 3 Results: Cosmology from Cosmic Shear and Robustness to Data Calibration
A. Amon, D. Gruen, M. A. Troxel +144
This work, together with its companion paper, Secco and Samuroff et al. (2021), presents the Dark Energy Survey Year 3 cosmic shear measurements and cosmological constraints based…
Dark Energy Survey Year 3 Results: High-precision measurement and modeling of galaxy-galaxy lensing
J. Prat, J. Blazek, C. Sánchez +138
We present and characterize the galaxy-galaxy lensing signal measured using the first three years of data from the Dark Energy Survey (DES Y3) covering 4132 deg. These galaxy-g…
Dark Energy Survey Year 3 results: curved-sky weak lensing mass map reconstruction
N. Jeffrey, M. Gatti, C. Chang +127
We present reconstructed convergence maps, \textit{mass maps}, from the Dark Energy Survey (DES) third year (Y3) weak gravitational lensing data set. The mass maps are weighted pro…
