Euclid: Cosmology forecasts from the void-galaxy cross-correlation function with reconstruction
Frédéric Courbin, Georges Meylan, Yi Wang, Richard Massey
We have investigated the cosmological constraints that can be expected from measurement of the cross-correlation of galaxies with cosmic voids identified in the Euclid spectroscopic survey, which will include spectroscopic information for tens of millions ...
EDP SCIENCES S A2023Cosmological constraints with the linear point from the BOSS survey
The Linear Point (LP), defined as the mid-point between the baryon acoustic oscillation (BAO) peak and the associated left dip of the two-point correlation function (2PCF), xi(s), is proposed as a new standard ruler which is insensitive to non-linear effec ...
Oxford2023Probing the nature of Dark Energy through the study of large scale structures using spectroscopic surveys and their simulations
Measurements of large-scale structure (LSS), as performed on the largest 3D map of over two million extragalactic sources from the Sloan Digital Sky Survey, together with measurements of the cosmic microwave background (CMB) anisotropies, are in complete a ...
EPFL2023Cosmology intertwined: A review of the particle physics, astrophysics, and cosmology associated with the cosmological tensions and anomalies
Frédéric Courbin, Richard Irving Anderson, Julien Lesgourgues, Mikhail Ivanov, Fabio Finelli, Adriano Agnello, Jie Wang, Florian Niedermann, Emre Ozulker, Melissa Joseph, Suresh Kumar, Hsin-Yu Chen
The standard Lambda Cold Dark Matter (Lambda CDM) cosmological model provides a good description of a wide range of astrophysical and cosmological data. However, there are a few big open questions that make the standard model look like an approximation to ...
ELSEVIER2022Angular systematics-free cosmological analysis of galaxy clustering in configuration space
Cheng Zhao, Anand Stéphane Raichoor
Galaxy redshift surveys are subject to incompleteness and inhomogeneous sampling due to the various constraints inherent to spectroscopic observations. This can introduce systematic errors on the summary statistics of interest, which need to be mitigated i ...
OXFORD UNIV PRESS2022Cosmological implications of the full shape of anisotropic clustering measurements in BOSS and eBOSS
We present the analysis of the full shape of anisotropic clustering measurement from the extended Baryon Oscillation Spectroscopic Survey (eBOSS) quasar sample together with the combined galaxy sample from the Baryon Oscillation Spectroscopic Survey (BOSS) ...
OXFORD UNIV PRESS2022Cosmology with Large Scale Structures using Massive Spectroscopic Surveys
Spectroscopic surveys aim to map large fractions of the Universe to study the Large Scale Structures (LSS). LSS evolution traces the distribution of matter as a result of the tension between the expansion of the Universe and the gravitational forces, which ...
EPFL2022Cosmic void baryon acoustic oscillation measurement: evaluation of sensitivity to selection effects
Jean-Paul Richard Kneib, Andrei Variu, Daniel Felipe Forero Sanchez, Cheng Zhao, Amélie Tamone
Cosmic voids defined as a subset of Delaunay triangulation (DT) circumspheres have been used to measure the baryon acoustic oscillations (BAO) scale; providing tighter constraints on cosmological parameters when combined with matter tracers. These voids ar ...
OXFORD UNIV PRESS2022Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Cosmological implications from two decades of spectroscopic surveys at the Apache Point Observatory
Jean-Paul Richard Kneib, Zheng Zheng, Andrei Variu, Cheng Zhao, Johan Comparat, Anand Stéphane Raichoor, Yuting Wang, Amélie Tamone
We present the cosmological implications from final measurements of clustering using galaxies, quasars, and Ly alpha forests from the completed Sloan Digital Sky Survey (SDSS) lineage of experiments in large-scale structure. These experiments, composed of ...
