Bayesian jackknife tests with a small number of subsets: Application to HERA 21cm power spectrum upper limits
Michael J. Wilensky, Fraser Kennedy, Philip Bull +2
We present a Bayesian jackknife test for assessing the probability that a data set contains biased subsets, and, if so, which of the subsets are likely to be biased. The test can b…
Antenna design for the SKA1-LOW and HERA super radio telescopes
Eloy de Lera Acedo, Hardie Pienaar, Nicolas Fagnoni
This paper summarizes the design process and metrics for the latest antenna design for 2 radio telescopes, SKALA4 for the SKA1-LOW instrument and the V-feed for the HERA telescope.…
Revisiting Hybrid Interferometry with Low-Frequency Radio Astronomy Arrays
Adrian T. Sutinjo, Daniel Ung, Tim M. Colegate +3
Radio interferometry most commonly involves antennas or antenna arrays of identical design. The identical antenna assumption leads to a convenient and useful mathematical simplific…
The Hydrogen Epoch of Reionization Array (HERA). Improvement of the antenna response with a matching network and scientific impacts
Nicolas Fagnoni, Eloy de Lera Acedo
The Hydrogen Epoch of Reionization Array (HERA) is a new powerful radio-telescope, dedicated to the study of the early universe. Its main goal is to characterise the period of the…
