To the First Stars and Back Again: How we can Learn about the Infant Universe

Up until very recently, the beginnings of star formation within our Universe have been largely observationally unexplored. However, with advancements of modern telescopes, we are now able to study this period of the Universe in multiple ways. While observations are still very challenging due to a host of foreground contaminants, combining observations at multiple wavelengths can lead to a greater understanding of distant populations of stars and galaxies at high redshifts. I will describe some of these observables, including high redshift galaxy surveys, the Cosmic Infrared Background, which is partially the integrated light from all stars and galaxies at high redshifts, and the 21cm Background, which results from emission from neutral gas. By piecing together these observables, we can learn more about some of the first stars and galaxies that formed within our Universe.
