Status Report on Observational 21cm Cosmology
Characterization of baryonic and dark matter structure in the intergalactic medium during the Epoch of Reionization (z~10) and the "pre-galactic" medium during Cosmic Dawn (z=20-30) is a frontier cosmological challenge. There is little data that directly constrains theory. I will review several early milestones in attempts to detect HI emission and absorption at these redshifts, focusing on the LEDA and EDGES projects that target the zero-mode at z~20, and the proposed EOS Array project that would be dedicated to detection of high-order modes during Cosmic Dawn.
