Zvonimir Vlah, visiting ORIGINS guest from the Ruder Bošković Institute, will give a talk on nonlinearities in the structure formation of the Universe.
The talk discusses recent developments in cosmological perturbation theory and the effective field theory (EFT) of large-scale structure.
Current galaxy surveys such as DESI and Euclid provide some of the cleanest probes of the Universe on large cosmological scales.
While the one-loop power spectrum (the two-point correlator) remains the standard and widely adopted theoretical tool, fully exploiting the potential of these new datasets requires extending our framework to higher loops and N-point correlators.
Zvonimir Vlah will outline the theoretical and computational challenges of going beyond the one-loop level and present recent results in the context of DESI and upcoming Euclid data.
