    DETAILS

    Observational cosmology is approaching a new era with a surge of spectroscopic galaxy redshift surveys all aimed at understanding the accelerated expansion of the Universe. A few notable examples are the Dark Energy Spectroscopic Instrument (DESI) and the ESA Euclid mission, which are obtaining their first scientific results. The primary probe of these surveys will be the baryon acoustic oscillations (BAO) imprinted in the large-scale structure (LSS) traced by galaxies. Galaxy clustering and the BAO probe of the expansion history of the Universe were proven by the hugely successful surveys of the last decade (BOSS, eBOSS, WiggleZ). In combination with the Planck cosmic microwave background analyses, the advancements in theory and analysis methods of LSS with these surveys brought us to the current point of achieving percent-level constraints on the parameters that describe the flat ΛCDM cosmological model. However, the increasingly precise measurements have only deepened the enigma surrounding the Λ term and dark energy that has been open for over 30 years.
    This meeting aims to discuss the latest advancements in the analysis of the LSS, exploiting both lower- and higher-order statistics from an observational and theoretical point of view, and also considering all the issues and mitigation strategies that need to be faced in real data analysis.
