PublicaciónDark energy survey year 3 results: cosmological constraints from the analysis of cosmic shear in harmonic space
We present cosmological constraints from the analysis of angular power spectra of cosmic shear maps based on data from the first three years of observations by...

PublicaciónDark Energy Survey Year 3 results: Curved-sky weak lensing mass map reconstruction
We present reconstructed convergence maps, mass maps, from the Dark Energy Survey (DES) third year (Y3) weak gravitational lensing data set. The mass maps are...

PublicaciónDark Energy Survey Year 3 results: galaxy-halo connection from galaxy-galaxy lensing
Galaxy-galaxy lensing is a powerful probe of the connection between galaxies and their host dark matter haloes, which is important both for galaxy evolution and...

PublicaciónDark Energy Survey Year 3 results: Imprints of cosmic voids and superclusters in the Planck CMB lensing map
The CMB lensing signal from cosmic voids and superclusters probes the growth of structure in the low-redshift cosmic web. In this analysis, we cross-correlated...

PublicaciónDark Energy Survey Year 3 results: magnification modelling and impact on cosmological constraints from galaxy clustering and galaxy-galaxy lensing
We study the effect of magnification in the Dark Energy Survey Year 3 analysis of galaxy clustering and galaxy-galaxy lensing, using two different lens samples...

PublicaciónDark Energy Survey Year 3 results: marginalization over redshift distribution uncertainties using ranking of discrete realizations
Cosmological information from weak lensing surveys is maximized by sorting source galaxies into tomographic redshift subsamples. Any uncertainties on these...

PublicaciónDark Energy Survey year 3 results: point spread function modelling
We introduce a new software package for modelling the point spread function (PSF) of astronomical images, called PIFF (PSFs In the Full FOV), which we apply to...

PublicaciónDark Energy Survey Year 3 results: redshift calibration of the MAGLIM lens sample from the combination of SOMPZ and clustering and its impact on cosmology
We present an alternative calibration of the MAGLIM lens sample redshift distributions from the Dark Energy Survey (DES) first 3 yr of data (Y3). The new...
