Rethinking Cosmology - The High-Redshift Universe and Reionization Studies - Day 3 Session 2

Explore cutting-edge cosmological research through this conference session featuring three expert presentations on high-redshift universe studies and their implications for fundamental cosmology. Delve into how the James Webb Space Telescope has revealed tensions in our understanding of early universe formation and learn how upcoming Square Kilometre Array observations will revolutionize cosmological measurements. Examine the cosmic reionization epoch as a powerful tool for probing dark matter and dark energy, investigating how the transition from neutral to ionized hydrogen in the early universe provides unique insights into cosmological parameters. Discover how 21-cm radio observations constrain models of the high-redshift universe, offering new perspectives on cosmic dawn and the formation of the first stars and galaxies. This session addresses current challenges to the standard ΛCDM cosmological model, including the Hubble tension and other observational anomalies that suggest the need for new theoretical frameworks. Gain insights into how next-generation observatories and innovative analysis techniques are reshaping our understanding of cosmic evolution, dark matter properties, and the fundamental structure of spacetime itself.
