The redshifted 21 cm line is an emerging tool in cosmology, in principle permitting three- dimensional surveys of our universe that reach unprecedentedly large volumes, previously …
The cosmic radio-frequency spectrum is expected to show a strong absorption signal corresponding to the 21-centimetre-wavelength transition of atomic hydrogen around …
