MeerKAT view of Hickson Compact Groups: II. HI deficiency in the core and surrounding regions
A. Sorgho, L. Verdes-Montenegro, R. Ianjamasimanana +25
Hickson compact groups (HCGs) offer an ideal environment for investigating galaxy transformation as a result of interactions. It has been established that the evolutionary sequence…
MeerKAT view of Hickson Compact Groups:I. Data description and release
R. Ianjamasimanana, L. Verdes-Montenegro, A. Sorgho +25
Context: Hickson Compact Groups (HCGs) are dense gravitationally-bound collections of 4-10 galaxies ideal for studying gas and star formation quenching processes. Aims: We aim to u…
MeerKAT HI imaging of the jellyfish galaxy ESO 137-001
M. Ramatsoku, P. Serra, M. Sun +2
We present MeerKAT HI observations of ESO 137-001, a quintessential jellyfish galaxy with long multi-phase tails formed due to the interaction with the intra-cluster medium of its…
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 detection of a massive chain of dark HI clouds in the GAMA G23 Field
Gyula I. G. Jozsa, T. H. Jarrett, Michelle Cluver +18
We report on the detection of a large, extended HI cloud complex in the GAMA G23 field, located at a redshift of , observed as part of the MeerHOGS campaign (a pilot…
MeerKAT-64 discovers wide-spread tidal debris in the nearby NGC 7232 galaxy group
Brenda Namumba, Baerbel Silvia Koribalski, Gyula I. G. Józsa +24
We report the discovery of large amounts of previously undetected cold neutral atomic hydrogen (\HI) around the core triplet galaxies in the nearby NGC~7232 galaxy group with MeerK…
The flickering nuclear activity of Fornax A
F. M. Maccagni, M. Murgia, P. Serra +13
We present new observations of Fornax A taken at 1 GHz with the MeerKAT telescope and at 6 GHz with the Sardinia Radio Telescope (SRT). The sensitive (noise ~16 micro-Jy beam$^{-1}…
