HERA

(Hydrogen Epoch of Reionization Array)
(low frequency radio telescope)

HERA (for Hydrogen Epoch of Reionization) is a radio telescope in South Africa operating at 100-200 MHz, aimed at detecting the hydrogen 21-cm line redshifted from the epoch of reionization (much like MWA and LOFAR). HERA's design borrows from their experiences, as well as that of PAPER, which has been declared to be HERA's Phase I.

HERA (proper) aims for a smaller field of view but more sensitivity, consisting of fixed 14-meter dishes in a tight array that view the sky as it pass over them. A 19-element array was put in service in 2017, and the National Radio Astronomy Observatory has provided funding to increase it to 240 elements in 2018.
