| Abstract: |
The earliest generations of galaxies are thought to have heated and reionized the universe. The most promising way to study cosmic reionization is to detect emission in the redshifted 21-cm line of atomic hydrogen. I will show how measurements of the 21-cm power spectrum should enable the simultaneous reconstruction of the reionization history and the properties of the ionizing sources. I will also present a detailed analysis of the 21-cm PDF (i.e., histogram of pixel values) and show that it offers an independent observational method for reconstructing the reionization history. |
