Mining the time axis with TRON - III. Discovery of a nulling pulsar towards the SMC with MeerKAT
T. Blecher, M. Geyer, O. M. Smirnov +21
We report on the discovery of a nulling pulsar, PSR J00527551, in archival MeerKAT L-band observations of the Small Magellanic Cloud (SMC). The discovery was made using the imag…
Mining the time axis with TRON. I. Millisecond pulsars in Omega Centauri, Terzan 5 and 47 Tucanae detected through MeerKAT interferometric imaging
Oleg M. Smirnov, Ian Heywood, Marisa Geyer +13
Medium-timescale (minutes to hours) radio transients are a relatively unexplored population. The wide field-of-view and high instantaneous sensitivity of instruments such as MeerKA…
Mining the time axis with TRON. II. MeerKAT detects a stellar radio flare from a distant RS CVn candidate
Oleg M. Smirnov, Aaron Golden, Talon Myburgh +14
Medium-timescale (minutes to hours) radio transients are a relatively unexplored population. The wide field-of-view and high instantaneous sensitivity of instruments such as MeerKA…
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…
Solution intervals considered harmful: on the optimality of radio interferometric gain solutions
Ulrich Armel Mbou Sob, Hertzog Landman Bester, Oleg M. Smirnov +2
Solution intervals are often used to improve the signal-to-noise ratio during radio interferometric gain calibration. This work investigates how factors such as the noise level, in…
