Automated detection of antenna malfunctions in large-n interferometers: A case study with the hydrogen epoch of reionization array
Storer, Dara; Dillon, Joshua S.; Kittiwisit, Piyanat (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
Kittiwisit, Piyanat; Bowman, Judd D.; Murray, Steven G. (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 ... -
A real time processing system for big data in astronomy: Applications to Hera
La Plante, Paul; Williams, Peter KG; Kittiwisit, Piyanat (Elsevier, 2021)As current- and next-generation astronomical instruments come online, they will generate an unprecedented deluge of data. Analyzing these data in real time presents unique conceptual and computational challenges, and their ... -
Validation of the HERA Phase I Epoch of Reionization 21 cm Power Spectrum Software Pipeline
Aguirre, James E.; Murray, Steven G.; Kittiwisit, Piyanat (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 ...
