Antenna beam characterization for the global 21-cm experiment LEDA and its impact on signal model parameter reconstruction
(Oxford University Press, 2022)
Cosmic dawn, the onset of star formation in the early universe, can in principle be studied via the 21-cm transition of neutral hydrogen, for which a sky-averaged absorption signal, redshifted to MHz frequencies, is predicted ...
Patterns of primary beam non-redundancy in close-packed 21 cm array observations
(Oxford University Press, 2021)
Radio interferometer arrays such as HERA consist of many close-packed dishes arranged in a regular pattern, giving rise to a
large number of ‘redundant’ baselines with the same length and orientation. Since identical ...
