Africanus I. Scalable, distributed and efficient radio data processing with Dask-MS and Codex Africanus
Simon J. Perkins, Jonathan S. Kenyon, Lexy A. L. Andati +3
New radio interferometers such as MeerKAT, SKA, ngVLA, and DSA-2000 drive advancements in software for two key reasons. First, handling the vast data from these instruments require…
Africanus IV. The Stimela2 framework: scalable and reproducible workflows, from local to cloud compute
Oleg M. Smirnov, Sphesihle Makhathini, Jonathan S. Kenyon +4
Stimela2 is a new-generation framework for developing data reduction workflows. It is designed for radio astronomy data but can be adapted for other data processing applications. S…
Africanus III. pfb-imaging -- a flexible radio interferometric imaging suite
Hertzog L. Bester, Jonathan S. Kenyon, Audrey Repetti +8
The popularity of the CLEAN algorithm in radio interferometric imaging stems from its maturity, speed, and robustness. While many alternatives have been proposed in the literature,…
Africanus II. QuartiCal: calibrating radio interferometer data at scale using Numba and Dask
Jonathan S. Kenyon, Simon J. Perkins, Hertzog L. Bester +3
Calibration of radio interferometer data ought to be a solved problem; it has been an integral part of data reduction for some time. However, as larger, more sensitive radio interf…
