First Constraints on Helium +He3 Evolution in z = 3–4 Using the 8.67 GHz Hyperfine Transition
We present the first constraints on the cross-correlation power spectrum of the He ii ( ^+ He ^3 ) signal strength using the redshifted 8.67 GHz hyperfine transition between z = 2.9 and 4.1 and with interferometric data obtained from the public archive of the Australia Telescope Compact Array (ATCA)...
