Speaker:  Prof. Naveen Reddy (University of California, Riverside)

Abstract:

A key issue in astrophysics is to uncover the sources responsible for ionizing hydrogen in the early Universe. Prof. Reddy will discuss how deep rest-frame UV spectroscopy of cosmologically-distant galaxies can be used to constrain pathways by which hydrogen-ionizing radiation escapes galaxies. Prof. Reddy will highlight a few observational proxies for escaping radiation and show how these measurements will be key for identifying and characterizing those galaxies that contribute to cosmic reionization.
