Project Title
Cosmology Theory Meets Data: Modelling Non-Linear Scales for Dark Energy Experiments
During the last few years, we have entered the “golden era” of observational cosmology. The standard cosmological model fits the data extremely well, but requires the existence of two exotic constituents, namely dark energy in the form of a cosmological constant, and cold dark matter. Dark energy currently dominates the Universe and it is responsible for its accelerated expansion.
