Higher-order statistics of the large-scale structure from photometric redshifts

Understand

The large-scale structure is a major source of cosmological information.

• However, next-generation photometric galaxy surveys will only provide a distorted view of cosmic structures due to large redshift uncertainties.
• To address the need for accurate reconstructions of the large-scale structure in presence of photometric uncertainties, we present a framework that constrains the three-dimensional dark matter density jointly with galaxy photometric redshift probability density functions (PDFs), exploiting information from galaxy clustering.
• Our forward model provides Markov Chain Monte Carlo realizations of the primordial and present-day dark matter density, inferred jointly from data.
