The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Cosmology with voids from the Nancy Grace Roman Space Telescope
Giovanni Verza, Giulia Degni, Alice Pisani +7
We provide an accurate forecast of the expected constraining power from the main void statistics -- the void size function and the void-galaxy cross-correlation function -- to be m…
A Parameter-Masked Mock Data Challenge for Beyond-Two-Point Galaxy Clustering Statistics
2pt Collaboration, Elisabeth Krause, Yosuke Kobayashi +23
The last few years have seen the emergence of a wide array of novel techniques for analyzing high-precision data from upcoming galaxy surveys, which aim to extend the statistical a…

Neutrino mass constraint from an Implicit Likelihood Analysis of BOSS voids
Leander Thiele, Elena Massara, Alice Pisani +4
Cosmic voids identified in the spatial distribution of galaxies provide complementary information to two-point statistics. In particular, constraints on the neutrino mass sum, $\su…

We investigate the cosmological constraints that can be expected from measurement of the cross-correlation of galaxies with cosmic voids identified in the Euclid spectroscopic surv…
DEMNUni: disentangling dark energy from massive neutrinos with the void size function
Giovanni Verza, Carmelita Carbone, Alice Pisani +1
Cosmic voids, the underdense regions in the Universe, are impacted by dark energy and massive neutrinos. In this work, relying on the DEMNUni suite of cosmological simulations, we…
The perspective of voids on rising cosmology tensions
Sofia Contarini, Alice Pisani, Nico Hamaus +3
We investigate the main tensions within the current standard model of cosmology from the perspective of the main statistics of cosmic voids, using the final BOSS DR12 data set. For…
Machine-learning cosmology from void properties
Bonny Y. Wang, Alice Pisani, Francisco Villaescusa-Navarro +1
Cosmic voids are the largest and most underdense structures in the Universe. Their properties have been shown to encode precious information about the laws and constituents of the…
