First Results from HERA Phase I: Upper Limits on the Epoch of Reionization 21 cm Power Spectrum

Show other versions (1)

We report upper limits on the Epoch of Reionization 21 cm power spectrum at redshifts 7.9 and 10.4 with 18 nights of data (∼36 hr of integration) from Phase I of the Hydrogen Epoch of Reionization Array (HERA). The Phase I data show evidence for systematics that can be largely suppressed with system...
