A distribution-free approach to test astrophysical models for angular power spectra

Oregon Convention Center 

This talk introduces a novel inferential strategy to test cosmological and astrophysical models for angular power spectra characterized by unknown parameters. We show that it is possible to assess the validity of such models without specifying the distribution of the estimators of the angular power spectrum being used. This holds true under rather general conditions, ensuring the applicability of the method across diverse scenarios. Moreover, the proposed solution overcomes the need for case-by-case simulations when testing different models - leading to remarkable advantages from a computational perspective.
