Euclid: Forecasts from the void-lensing cross-correlation
M. Bonici, C. Carbone, S. Davini +129
The Euclid space telescope will survey a large dataset of cosmic voids traced by dense samples of galaxies. In this work we estimate its expected performance when exploiting angula…
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…
Gravitation And the Universe from large Scale-Structures: The GAUSS mission concept
Alain Blanchard, Aubourg Éric, Philippe Brax +25
Today, thanks in particular to the results of the ESA Planck mission, the concordance cosmological model appears to be the most robust to describe the evolution and content of the…
The Completed SDSS-IV Extended Baryon Oscillation Spectroscopic Survey: Growth rate of structure measurement from cosmic voids
Marie Aubert, Marie-Claude Cousinou, Stéphanie Escoffier +19
We present a void clustering analysis in configuration-space using the completed Sloan Digital Sky Survey IV (SDSS-IV) extended Baryon Oscillation Spectroscopic Survey (eBOSS) DR16…
The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Cosmological Implications from two Decades of Spectroscopic Surveys at the Apache Point observatory
eBOSS Collaboration, Shadab Alam, Marie Aubert +97
We present the cosmological implications from final measurements of clustering using galaxies, quasars, and Ly forests from the completed Sloan Digital Sky Survey (SDSS) lineage…
Peculiar velocity cosmology with type Ia supernovae
R. Graziani, M. Rigault, N. Regnault +20
Type Ia Supernovae have yet again the opportunity to revolutionize the field of cosmology as the new generation of surveys are acquiring thousands of nearby SNeIa opening a new era…
Cosmological constraints from cosmic homogeneity
Pierros Ntelis, Adam James Hawken, Stephanie Escoffier +2
In this paper, we study the normalised characteristic scale of transition to cosmic homogeneity, , as a cosmological probe. We use a compilation of SDSS galaxy s…
Inflation and Dark Energy from spectroscopy at
Simone Ferraro, Michael J. Wilson, Muntazir Abidi +140
The expansion of the Universe is understood to have accelerated during two epochs: in its very first moments during a period of Inflation and much more recently, at , when D…
Primordial Non-Gaussianity
P. Daniel Meerburg, Daniel Green, Muntazir Abidi +175
Our current understanding of the Universe is established through the pristine measurements of structure in the cosmic microwave background (CMB) and the distribution and shapes of…
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…
The scale of cosmic homogeneity as a standard ruler
Pierros Ntelis, Anne Ealet, Stephanie Escoffier +5
In this paper, we study the characteristic scale of transition to cosmic homogeneity of the universe, , as a standard ruler, to constrain cosmological parameters on…
Massive Neutrinos Leave Fingerprints on Cosmic Voids
Christina D. Kreisch, Alice Pisani, Carmelita Carbone +5
Do void statistics contain information beyond the tracer 2-point correlation function? Yes! As we vary the sum of the neutrino masses, we find void statistics contain information a…
Measuring the Universe with galaxy redshift surveys
L. Guzzo, J. Bel, D. Bianchi +7
Galaxy redshift surveys are one of the pillars of the current standard cosmological model and remain a key tool in the experimental effort to understand the origin of cosmic accele…
The VIMOS Public Extragalactic Redshift Survey: Measuring the growth rate of structure around cosmic voids
A. J. Hawken, B. R. Granett, A. Iovino +33
We identified voids in the completed VIMOS Public Extragalactic Redshift Survey (VIPERS), using an algorithm based on searching for empty spheres. We measured the cross-correlation…
Testing the lognormality of the galaxy and weak lensing convergence distributions from Dark Energy Survey maps
L. Clerkin, D. Kirk, M. Manera +57
It is well known that the probability distribution function (PDF) of galaxy density contrast is approximately lognormal; whether the PDF of mass fluctuations derived from weak lens…
The Integrated Sachs-Wolfe Signal from BOSS Super-Structures
Benjamin R. Granett, András Kovács, Adam J. Hawken
Cosmic structures leave an imprint on the microwave background radiation through the integrated Sachs-Wolfe effect. We construct a template map of the linear signal using the SDSS-…
Effective dark matter power spectra in gravity
Jian-hua He, Baojiu Li, Adam J. Hawken
Using N-body simulations, we measure the power spectrum of the effective dark matter density field, which is defined through the modified Poisson equation in cosmologies. We…
