Learn how to test multi-field inflation models using observational data from galaxy surveys in this 18-minute conference talk. Explore the theoretical framework of multi-field inflation and discover how the galaxy power spectrum and bispectrum serve as powerful observational tools for constraining inflationary scenarios. Examine the statistical methods used to extract cosmological information from large-scale structure data and understand how these measurements can distinguish between single-field and multi-field inflationary models. Gain insights into the current observational constraints on inflation parameters and the prospects for future galaxy surveys to further test these fundamental cosmological theories.
