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…
A Spectropolarimetric Study of Pictor A Radio Galaxy with MeerKAT
Lexy A. L. Andati, Lerato M. Baidoo, Athanaseus J. T. Ramaila +3
We present the results of a polarimetric study from our new high-sensitivity L-band (0.8--1.7 GHz) observation of Pictor A with the MeerKAT radio telescope. We confirm the presence…
PolarVis: Towards Web-based Polarimetric Analysis
Lexy A. L. Andati, O. M. Smirnov, S. Makhathini +1
Astronomers performing polarimetric analysis on astronomical images often have to manually identify locations on their objects of interest, such as galaxies, which exhibit the infl…
The extended HI halo of NGC 4945 as seen by MeerKAT
Roger Ianjamasimanana, B. S. Koribalski, Gyula I. G. Józsa +20
Observations of the neutral atomic hydrogen (HI) in the nuclear starburst galaxy NGC 4945 with MeerKAT are presented. We find a large amount of halo gas, previously missed by HI ob…
Anomalous gas in ESO 149-G003: A MeerKAT-16 View
Gyula I. G. Józsa, Kshitij Thorat, Peter Kamphuis +28
ESO 149-G003 is a close-by, isolated dwarf irregular galaxy. Previous observations with the ATCA indicated the presence of anomalous neutral hydrogen (HI) deviating from the kinema…
MeerKAT's discovery of a radio relic in the bimodal merging cluster A2384
V. Parekh, K. Thorat, R. Kale +12
We present the discovery of a single radio relic located at the edge of the galaxy cluster A2384, using the MeerKAT radio telescope. A2384 is a nearby ( = 0.092), low mass, comp…
MeerKAT-16 HI observation of the dIrr galaxy WLM
Roger Ianjamasimanana, Brenda Namumba, Athanaseus J. T. Ramaila +19
We present observations and models of the kinematics and the distribution of the neutral hydrogen (HI) in the isolated dwarf irregular galaxy, Wolf-Lundmark-Melotte (WLM). We obser…
GASP XXVI. HI Gas in Jellyfish Galaxies: The case of JO201 and JO206
M. Ramatsoku, P. Serra, B. M. Poggianti +21
We present HI observations of the jellyfish galaxy, JO201. This massive galaxy (M M) is falling along the line-of-sight towards the centre of…
MeerKATHI -- an end-to-end data reduction pipeline for MeerKAT and other radio telescopes
Gyula I. G. Józsa, Sarah V. White, Kshitij Thorat +13
MeerKATHI is the current development name for a radio-interferometric data reduction pipeline, assembled by an international collaboration. We create a publicly available end-to-en…
Collimated synchrotron threads linking the radio lobes of ESO137-006
M. Ramatsoku, M. Murgia, V. Vacca +14
We present MeerKAT 1000 MHz and 1400 MHz observations of a bright radio galaxy in the southern hemisphere, ESO~137-006. The galaxy lies at the centre of the massive and merging Nor…
