Cosmological evolution of matter with interacting dust fluids
Geoffrey Okeng'o, Nceba Mhlahlo, Roy Maartens
We split the total matter fluid into a bound (halo) component and an unbound (free particles) fluid component that is accreted by the halos. We adopt a different framework that tre…
The MeerKAT Galaxy Cluster Legacy Survey I. Survey Overview and Highlights
K. Knowles, W. D. Cotton, L. Rudnick +148
MeerKAT's large number of antennas, spanning 8 km with a densely packed 1 km core, create a powerful instrument for wide-area surveys, with high sensitivity over a wide range of an…
Revealing the Unusual Structure of the KAT-7-Discovered Giant Radio Galaxy J01331302
Nceba Mhlahlo, Marek Jamrozy
We present a new study of the 1.7 Mpc KAT-7-discovered giant radio galaxy, J01331302, which was carried out using GMRT data at 323 and 608 MHz. This source is located at RA $01^…
Discovery of a shock front in the merging cluster of galaxies A2163
Nceba Mhlahlo, Loic Guennou, Luigina Feretti
ACO2163 is one of the hottest (mean keV) and extremely X-ray overluminous merging galaxy clusters which is located at . The cluster hosts one of the largest g…
Discovery of a suspected giant radio galaxy with the KAT-7 array
S. Colafrancesco, N. Mhlahlo, T. Jarrett +2
We detect a new suspected giant radio galaxy (GRG) discovered by KAT-7. The GRG core is identified with the WISE source J013313.50-130330.5, an extragalactic source based on its in…
Multi-frequency constraints on the non-thermal pressure in galaxy clusters
S. Colafrancesco, M. S. Emritte, N. Mhlahlo +1
The origin of radio halos in galaxy clusters is still unknown and is the subject of a vibrant debate both from the observational and theoretical point of view. In particular the am…
