Impact of Small-Scale Structure on Reionization - Hyunbae Park

Explore the impact of small-scale structure on cosmic reionization in this 26-minute conference talk by Hyunbae Park from Lawrence Berkeley National Laboratory. Delivered at the "Co-evolution of the Cosmic Web and Galaxies across Cosmic Time" conference at the Kavli Institute for Theoretical Physics, this presentation delves into the intricate relationship between the cosmic web and galaxy formation. Gain insights into how small-scale structures influence the reionization process, a crucial phase in the early universe. Examine the latest research on the thermal web at high redshifts, the distribution of early galaxies and quasars within the cosmic web, and the interaction between ionization fronts and the web's structure. Understand the implications of these findings for cosmology, dark energy, and primordial non-Gaussianity, as well as their significance in constraining models of structure formation and modified gravity.
