Description

The CMB was first measured at radio wavelengths, but most measurements these days are done at mm wavelengths. It is still there, in the radio, we should measure the fluctuations there. I'll show some preliminary cross-power spectra of high-frequency radio maps and Planck, and advocate for doing this with experiments targeting cosmic dawn as a new handle on the evolution of the 21cm spin temperature.
