Data Release 1 of the Dark Energy Spectroscopic Instrument Open
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving three-dimensional structure of the universe between $z=0$ and $z\approx4$. DES…

The gravitational lensing imprints of DES Y3 superstructures on the CMB: a matched filtering approach Open
Low-density cosmic voids gravitationally lens the cosmic microwave background (CMB), leaving a negative imprint on the CMB convergence $\kappa$. This effect provides insight into the distribution of matter within voids, and can also be use…

Dark Energy Survey Year 3 results: Imprints of cosmic voids and superclusters in the <i>Planck</i> CMB lensing map Open
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 the Planck CMB lensing map with voids detected in the Dark Energy Survey Year 3…

Dark Energy Survey Year 3 results: Curved-sky weak lensing mass map reconstruction Open
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 weighted projections of the density field (primarily dark matter) in the foregro…

Dark Energy Survey Year 1 results: the lensing imprint of cosmic voids on the cosmic microwave background Open
Cosmic voids gravitationally lens the cosmic microwave background (CMB) radiation, resulting in a distinct imprint on degree scales. We use the simulated CMB lensing convergence map from the Marenostrum Institut de Ciencias de l’Espai (MIC…
