Rethinking Cosmology - The High-Redshift Universe as a Cosmological Laboratory - Day 4 Session 2

Explore cutting-edge cosmological research through this conference session featuring three expert presentations on high-redshift universe studies and their implications for modern cosmology. Delve into how recent JWST observations are creating tensions with standard cosmological models as Tirthankar Roy Choudhury examines the high-redshift universe as a cosmological laboratory and discusses prospects for the upcoming SKA era. Learn how cosmic reionization serves as a powerful tool for probing dark sector physics through Girish Kulkarni's analysis of the transition from the last neutral islands in the universe to our current understanding of dark matter and dark energy. Discover how 21-cm radio observations provide unique constraints on the early universe through Saurabh Singh's presentation on using these signals to study high-redshift cosmological phenomena. Gain insights into the current challenges facing the standard ΛCDM cosmological model, including the Hubble tension and other observational anomalies, while exploring how next-generation observatories like SKA, Rubin-LSST, and future CMB missions will revolutionize our understanding of cosmic evolution, dark matter, and dark energy in the coming decade.
