Description
Upcoming and ongoing cosmological surveys, such as Euclid and DESI, are mapping the distribution of tens of millions of galaxies across cosmic time. These data sets will provide unprecedented opportunities to constrain the fundamental physical theory governing the Universe, including the nature of gravity, dark matter and dark energy. To fully exploit this potential, however, one must reconstruct the past matter distribution, before nonlinear gravitational evolution transformed the early density field into the complex large-scale structure observed in the late-time Universe. This talk will review key results and discuss several of the methods developed to achieve this goal.
