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…
HI gas in the rejuvenated radio galaxy PKS 2014-55
Leon Mtshweni, Kshitij Thorat, Roger P. Deane +17
We present new high-spectral-resolution MeerKAT observations of absorption against the central region of the restarted, giant, X-shaped radio galaxy PKS2014-55, which…
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…
