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 ...
Statistical recovery of 21 cm visibilities and their power spectra with gaussian-constrained realizations and gibbs sampling
(The Astrophysical Journal Supplement Series, 2023)
Radio interferometers designed to probe the 21 cm signal from Cosmic Dawn and the Epoch of Reionization must contend with systematic effects that make it difficult to achieve sufficient dynamic range to separate the 21 cm ...
