Speaker Institution: 
University of California, Riverside
Talk Title: 
Recent Progress Toward Understanding Cosmological Reionization
Event description: 

When the first galaxies formed, their starlight likely reionized and heated the intergalactic hydrogen that had existed since recombination.  In the past few years, there has been significant progress toward understanding the reionization process.  I will highlight this progress, including the possibility that we have already observed evidence of reionization’s tail end in the spectra of high-redshift quasars.  I will also discuss the role that small-scale structure in the cosmic web played in shaping reionization, and what we might learn about cosmology from reionization observables.
