Rethinking Cosmology - Day 2 Session 1

Explore cutting-edge cosmological research through this conference session featuring two distinguished speakers examining fundamental questions about our universe's structure and evolution. Delve into Alexandre Réfrégier's presentation on novel approaches to cosmological constraints, which introduces innovative methodologies for understanding cosmic parameters and testing theoretical models against observational data. Follow with Changbom Park's detailed analysis challenging dynamically evolving dark energy scenarios through the Alcock-Paczyński test applied to redshift-space correlation functions, providing crucial insights into the nature of dark energy's role in cosmic expansion. Learn about advanced statistical techniques, observational strategies, and theoretical frameworks that are reshaping our understanding of the ΛCDM model amid growing tensions and anomalies in cosmological data. Gain insights into how modern astronomical surveys and sophisticated analysis methods are being employed to address fundamental questions about dark matter, dark energy, and the overall architecture of the cosmos. Understand the implications of these findings for future cosmological research and the ongoing efforts to reconcile discrepancies between early and late universe observations that challenge our current cosmological paradigm.
