Euclid: Cosmological forecasts from the void size function

S. Contarini, G. Verza, A. Pisani +123

The Euclid mission with its spectroscopic galaxy survey covering a sky area over in the redshift range will provide a sample of tens o…

Dark Energy Survey Year 3 results: imprints of cosmic voids and superclusters in the Planck CMB lensing map

A. Kovács, P. Vielzeuf, I. Ferrero +82

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 lensi…

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…

Euclid: Forecasts from redshift-space distortions and the Alcock-Paczynski test with cosmic voids

N. Hamaus, M. Aubert, A. Pisani +127

Euclid is poised to survey galaxies across a cosmological volume of unprecedented size, providing observations of more than a billion objects distributed over a third of the full s…

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…

Dark Energy Survey Year 1 Results: the lensing imprint of cosmic voids on the Cosmic Microwave Background

P. Vielzeuf, A. Kovács, U. Demirbozan +62

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 ma…

Dark Energy Survey Year 1 results: The relationship between mass and light around cosmic voids

Y. Fang, N. Hamaus, B. Jain +74

What are the mass and galaxy profiles of cosmic voids? In this paper we use two methods to extract voids in the Dark Energy Survey (DES) Year 1 redMaGiC galaxy sample to address th…

The bias of cosmic voids in the presence of massive neutrinos

Nico Schuster, Nico Hamaus, Alice Pisani +4

Cosmic voids offer an extraordinary opportunity to study the effects of massive neutrinos on cosmological scales. Because they are freely streaming, neutrinos can penetrate the int…

Cosmic voids: a novel probe to shed light on our Universe

Alice Pisani, Elena Massara, David N. Spergel +26

Cosmic voids, the less dense patches of the Universe, are promising laboratories to extract cosmological information. Thanks to their unique low density character, voids are extrem…

On the relative bias of void tracers in the Dark Energy Survey

G. Pollina, N. Hamaus, K. Paech +61

Luminous tracers of large-scale structure are not entirely representative of the distribution of mass in our Universe. As they arise from the highest peaks in the matter density fi…

Dark Energy Survey Year 1 Results: Weak Lensing Mass Calibration of redMaPPer Galaxy Clusters

T. McClintock, T. N. Varga, D. Gruen +99

We constrain the mass--richness scaling relation of redMaPPer galaxy clusters identified in the Dark Energy Survey Year 1 data using weak gravitational lensing. We split clusters i…

On the linearity of tracer bias around voids

Giorgia Pollina, Nico Hamaus, Klaus Dolag +3

The large-scale structure of the universe can only be observed via luminous tracers of the dark matter. However, the clustering statistics of tracers are biased and depend on vario…

Cosmic voids in coupled dark energy cosmologies: the impact of halo bias

Giorgia Pollina, Marco Baldi, Federico Marulli +1

In this work we analyse the properties of cosmic voids in standard and coupled dark energy cosmologies. Using large numerical simulations, we investigate the effects produced by th…

Cosmic voids detection without density measurements

Andrii Elyiv, Federico Marulli, Giorgia Pollina +4

Cosmic voids are effective cosmological probes to discriminate among competing world models. Their identification is generally based on density or geometry criteria that, because o…
