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…
Single frequency CMB B-mode inference with realistic foregrounds from a single training image
Niall Jeffrey, François Boulanger, Benjamin D. Wandelt +3
With a single training image and using wavelet phase harmonic augmentation, we present polarized Cosmic Microwave Background (CMB) foreground marginalization in a high-dimensional…
Dark Energy Survey Year 3 results: Cosmology with peaks using an emulator approach
D. Zürcher, J. Fluri, R. Sgier +119
We constrain the matter density and the amplitude of density fluctuations within the CDM cosmological model with shear peak statistics and angular converg…
Dark Energy Survey Year 3 results: cosmology with moments of weak lensing mass maps
M. Gatti, B. Jain, C. Chang +107
We present a cosmological analysis using the second and third moments of the weak lensing mass (convergence) maps from the first three years of data (Y3) data of the Dark Energy Su…
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: 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: 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…
Weak lensing mass reconstruction using sparsity and a Gaussian random field
J. -L. Starck, K. E. Themelis, N. Jeffrey +2
We introduce a novel approach to reconstruct dark matter mass maps from weak gravitational lensing measurements. The cornerstone of the proposed method lies in a new modelling of t…
A new approach for the statistical denoising of Planck interstellar dust polarization data
Bruno Regaldo-Saint Blancard, Erwan Allys, François Boulanger +2
Dust emission is the main foreground for cosmic microwave background (CMB) polarization. Its statistical characterization must be derived from the analysis of observational data be…
