Model-Independent Methods for Determining Cosmological Parameters

Explore a detailed lecture by Professor Luca Amendola from the University of Heidelberg that delves into model-independent approaches for determining cosmological parameters. Learn how to estimate fundamental quantities like the cosmological expansion rate H(z) and deviations from Einstein gravity without relying on specific cosmological models like ΛCDM. Discover techniques for combining multiple observational methods including redshift distortions, gravitational lensing, and matter clustering to obtain model-independent results. Gain insights into why current parameter estimations from CMB surveys and large-scale structure analyses are typically model-dependent, and understand alternative approaches for obtaining more universal cosmological measurements.
