SubsidieMeestersA Cosmological Lever Arm for Fundamental Physics
The project aims to enhance measurements of the Universe's expansion rate and density fluctuations using 3D correlations in the Lyman forest, potentially advancing our understanding of neutrino masses and inflationary models.
Projectdetails
Introduction
Key open questions in the boundary of cosmology and fundamental physics can be addressed by studies of the distribution of matter as a function of scale and time (or redshift). While the traditional approach has been to use large galaxy catalogues, during the last decade I have pioneered the use of an alternative probe: 3D correlations in the Lyman- (Ly) forest, absorption features in the spectra of high-redshift quasars caused by intervening neutral hydrogen. The Ly forest provides a unique window to study the distribution of matter at earlier times and on smaller scales than those accessible with galaxy catalogues.
Project Overview
I lead the Ly analysis of the Dark Energy Spectroscopic Instrument (DESI) survey, and with ERC support, I will be able to develop and apply new techniques to dramatically enhance its expected outcome.
COSMO-LYA Goals
On one hand, COSMO-LYA will use the correlations on large (> 30 Mpc) scales to obtain a 0.5% measurement of the expansion rate of the Universe at z > 2, four times better than the state-of-the-art.
On the other hand, we will carry out the first coherent analysis of 1D and 3D correlations to provide a 1% measurement of the amplitude of density fluctuations on small (~1 Mpc) scales, unreachable by other probes.
Cosmological Lever Arm
In combination with public CMB results, sensitive to the distribution of matter at early times and on the largest scales, we will be able to construct a cosmological lever arm covering 4 orders of magnitude in scale.
Expected Outcomes
This will enable my team to:
- Increase by at least a factor of 2 the constraints on the sum of the neutrino masses, potentially leading to the first measurement of the absolute neutrino masses.
- Increase by at least a factor of 3 our constraints on the shape of the primordial power spectrum of density fluctuations, an important step towards confirming or falsifying a large number of inflationary models.
Interdisciplinary Impact
These results will have interdisciplinary impact, with wide-reaching consequences in particle and fundamental physics.
