The Promise and Challenge of 21 cm Cosmology

Abstract: 21 cm Cosmology has the potential to be the future of observational cosmology. By measuring the redshifted radio line of neutral hydrogen, 21 cm Cosmology can map the effects of Dark Energy, reveal the Epoch of Reionization, and even constrain the Dark Sector by observing small scale primordial fluctuations during the Dark Ages. Realizing this potential, however, necessitates solving the exquisite experimental precision and data analysis challenges needed to isolate the faint cosmological signal. I will talk about the potential of 21 cm Cosmology, describe the experimental challenges, and discuss the current state of the art with the deepest 21 cm Cosmology limits from the Epoch of Reionization.
