Validation of the HERA Phase I Epoch of Reionization 21 cm Power Spectrum Software Pipeline
(The American Astronomical Society., 2022)
We describe the validation of the HERA Phase I software pipeline by a series of modular tests, building up to an
end-to-end simulation. The philosophy of this approach is to validate the software and algorithms used in ...
Automated detection of antenna malfunctions in large-n interferometers: A case study with the hydrogen epoch of reionization array
(2022)
We present a framework for identifying and flagging malfunctioning antennas in large radio
interferometers. We outline two distinct categories of metrics designed to detect outliers along known failure
modes of large ...
Measurements of one-point statistics in 21-cm intensity maps via foreground avoidance strategy
(Oxford University Press, 2022)
Measurements of the one-point probability distribution function and higher-order moments (variance, skewness, and kurtosis) of
the high-redshift 21-cm fluctuations are among the most directstatistical probes of the ...
