The highly redshifted 21 cm emission line from neutral hydrogen has the potential to reveal the temperature, density, and ionization fraction of the IGM during the Cosmic Dawn, when the first stars and galaxies illuminated the universe. The Long Wavelength Array at the Owens Valley Radio Observatory (OVRO-LWA) is currently undergoing an upgrade that substantially improves its sensitivity to...
