Explore cutting-edge cosmological research through three comprehensive conference presentations examining the high-redshift universe and its implications for our understanding of cosmology. Delve into how recent JWST observations have created tensions with the standard ΛCDM model and discover how upcoming SKA observations will revolutionize our cosmological laboratory capabilities. Learn about reionization processes and how they serve as powerful tools for probing dark sector physics, from the final neutral hydrogen islands to broader cosmological implications. Investigate 21-cm signal constraints and their role in understanding the early universe's evolution and cosmological parameters. Gain insights into how these observational frontiers are challenging established cosmological frameworks and opening new avenues for testing fundamental physics through astronomical observations.
