Abstract

The 21cm line can be used to conduct large-volume surveys of the high-z universe, probing both astrophysics and cosmology. We highlight the promise of using the 21cm line to constrain cosmology via z>6 observations, emphasizing the key advances and investments required to access the potentially vast information content of future surveys.
