New Cosmology group paper
January 12, 2023
Observational Cosmology Group“Cosmological Fisher forecasts for next-generation spectroscopic surveys ” by William Doumerg and collaborators has been uploaded to arXiv.
In this paper we perform a Fisher matrix analysis for future spectroscopic surveys (MegaMapper, MUST…) on the BAO, RSD, the non-Gaussianity amplitude, and the total neutrino mass. These surveys will have a large number of fibres (~20,000), and study the high redshift universe (z>2). In addition, we model the observations of a spectroscopic survey with free observational parameters (redshift range, sky coverage, efficiency threshold…), and we derive the optimal ones for non-Gaussianity and neutrino mass measurements, and study the fibre increase effect.

New Planetarium show - '5000 Eyes: Mapping the Universe with DESI'
June 13, 2023
A stunning documentary film featuring recent discoveries from the Dark Energy Spectroscopic Instrument (DESI) has been released to planetariums worldwide. A catalan version of this new documentary has been produced by the ERC COSMO-LYA project in collaboration with the UAB.
