Probing the redshift evolution of radio halos is an important test of the turbulent re-acceleration scenario, as fewer halos are expected at high redshift, given the same mass interval. In this thesis, we present MeerKAT observations at 1.28 GHz of three high-redshift (PSZ2G254.08- 58.45, PSZ2G255.60-46.18 and PSZ2G277.76-51.74, in the 0.42 ≲ z ≲ 0.46 range) clusters, with masses M500 ≳ 6.2 × 1014 M⊙, selected for their disturbed dynamical state – inferred from existing X-ray observations. Our observations reached rms noise values between 20 and 23.5 μJy beam−1, with ∼ 4′′ angular resolution. No evidence of diffuse emission is found at ii full resolution. Low-resolution (∼ 30′′) images achieved rms noise levels of 30-50 μJy beam−1, amongst the deepest observations of high-redshift targets. One radio halo was detected in the least massive cluster PSZ2G254.08-58.45 extending over ∼ 500 kpc, with a 1.20 } 0.08 mJy integrated flux density. We placed a ∼1 mJy upper limit at 95% confidence level on the radio halo flux density for the other two targets. The radio-halo detection is consistent with the recent P1.4 GHz − M500 correlation from Cuciti et al. (2021b), while the upper limit on PSZ2G255.60-46.18 is consistent with being on the correlation. On the other hand, the upper limit on PSZ2G277.76-51.74 places the radio halo well below the correlation. Recently a 1.5 GHz survey (Giovannini et al., 2020) detected a slightly higher fraction of radio halos in clusters in the same redshift range, with power and size typically higher than what we found in our observations. Both observations are, however, not inconsistent with each other. Our results, although with limited statistics, do not disfavour the current scenario of radiohalo formation based on the turbulent re-acceleration model.]]> Thu 04 Apr 2024 19:25:15 SAST ]]> Implications of changing land use and introducing extralimital giraffe on vegetation in the subtropical thicket, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:71935 Thu 04 Apr 2024 19:11:09 SAST ]]> Quantifying feed intake and feeding intensity using two experimental conditions and the effect of different feeding strategies on the production parameters of farmed South African abalone, haliotis midae https://vital.seals.ac.za/vital/access/manager/Repository/vital:71932 Thu 04 Apr 2024 19:04:28 SAST ]]> Source of introduced populations of Hemidactylus mabouia (Moreau de Jonnès, 1818) into the Eastern Cape Province and the potential spread to other South African regions https://vital.seals.ac.za/vital/access/manager/Repository/vital:71933 Thu 04 Apr 2024 19:04:14 SAST ]]> Coastal movements and estuarine use of sub-adult and adult leervis, lichia amia: results from long-term acoustic tracking https://vital.seals.ac.za/vital/access/manager/Repository/vital:71930 Thu 04 Apr 2024 18:57:36 SAST ]]> Distribution and conservation status assessment of the freshwater fishes in the Krom River system in the Eastern Cape Province, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:71929 Thu 04 Apr 2024 18:50:26 SAST ]]> Biological longitudinal aspects of the Kabompo River, a significant tributary of the upper Zambezi sub-catchment, North-west Province, Zambia https://vital.seals.ac.za/vital/access/manager/Repository/vital:71928 Thu 04 Apr 2024 17:34:04 SAST ]]> A Comparison of Mitochondrial Heat Shock Protein 70 and Hsp70 Escort Protein 1 Orthologues from Trypanosoma brucei and Homo sapiens https://vital.seals.ac.za/vital/access/manager/Repository/vital:71927 Thu 04 Apr 2024 17:12:57 SAST ]]> The influence of immuno-contraception on the ecology of African savanna elephants (Loxodonta africana) in a small game reserve in the Eastern Cape, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:71926 Thu 04 Apr 2024 16:59:13 SAST ]]> Microbial and extracellular polymeric substance dynamics in arid–zone temporary pan ecosystems https://vital.seals.ac.za/vital/access/manager/Repository/vital:71925 Thu 04 Apr 2024 16:51:48 SAST ]]> Investigating teachers’ perceptions on translanguaging pedagogy in a multilingual intermediate ESL classroom: a comparative study of two primary schools in Namibia https://vital.seals.ac.za/vital/access/manager/Repository/vital:71673 Sun 25 Feb 2024 09:52:15 SAST ]]> A distributed approach to leadership in an academic department in a South African university: an exploratory case study https://vital.seals.ac.za/vital/access/manager/Repository/vital:71672 Sun 25 Feb 2024 09:37:05 SAST ]]> The effects of inclusive education policies and administrative circulars on small schools in Namibia https://vital.seals.ac.za/vital/access/manager/Repository/vital:71671 Sun 25 Feb 2024 09:36:40 SAST ]]> Using the indigenous technology of making oshikundu to mediate learning of the topic diffusion in Namibia https://vital.seals.ac.za/vital/access/manager/Repository/vital:71670 Sun 25 Feb 2024 09:23:12 SAST ]]> Exploring ESL teachers’ self-developed pedagogical practices for teaching reading comprehension in Namibian primary schools https://vital.seals.ac.za/vital/access/manager/Repository/vital:71669 Sun 25 Feb 2024 09:09:41 SAST ]]> The political economy of industrial policy in post-apartheid South Africa: a comparative case study analysis of Brazil and South Korea https://vital.seals.ac.za/vital/access/manager/Repository/vital:71668 Sun 25 Feb 2024 09:08:49 SAST ]]> The yield spread as a predictor for buy or sell signals for sectoral indices of the JSE https://vital.seals.ac.za/vital/access/manager/Repository/vital:71666 Sun 25 Feb 2024 08:55:01 SAST ]]> Examining the expenditures and retention of money of recreational fishing along the Wild Coast, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:71665 Sun 25 Feb 2024 08:06:56 SAST ]]> The role of local level agency in a just green transition: the case of Rhodes University https://vital.seals.ac.za/vital/access/manager/Repository/vital:71662 Sun 25 Feb 2024 07:31:58 SAST ]]> The complexities of transfer pricing methods and the role of advance pricing agreements and tax audits in addressing disputes https://vital.seals.ac.za/vital/access/manager/Repository/vital:71661 Sun 25 Feb 2024 07:23:54 SAST ]]> Philosophical inquiry into the value of liberal education https://vital.seals.ac.za/vital/access/manager/Repository/vital:70540 Sun 10 Dec 2023 14:16:57 SAST ]]> Pathi’s sister is still troubling https://vital.seals.ac.za/vital/access/manager/Repository/vital:70539 Sun 10 Dec 2023 14:06:16 SAST ]]> Which Black Lives matter?

Observations of TIDs are made using Global Navigational Satellite Systems (GNSS) total electron content derived data. During quiet conditions, seven and two transhemispheric TIDs were identified over the African-European and American sectors, respectively. The observed TIDs originated from the wintertime hemisphere and propagated into the summertime hemisphere. The horizontal velocity, periods, and horizontal wavelengths of TIDs are in range of cH = 120-274 m/s, 48-80 min and _H = 379-1104 km, respectively. These quiet-time equatorward TIDs have been associated with tertiary gravity waves (GWs) from the dissipation of secondary GWs which are in turn generated from the dissipation of mountain waves (MWs) as a result of excited orographic forcing. The poleward TIDs during geomagnetically quiet conditions over the African and American sectors occur mainly during local daytime. Poleward TIDs were observed mostly in the African-European sector than the American sector. Their horizontal propagation velocities and periods range between 129-280 m/s and 39-70 min over African-European and American sectors. Although the mechanisms responsible for launching quiet-time poleward TIDs have not been established in this study, lower atmospheric processes such as convection systems, sudden stratospheric warming and cold weather fronts may have a role in their generation. During geomagnetic storms in the African sector, almost all poleward TIDs (with the exception of two cases) during the main phase were large-scale with horizontal velocities and periods ranging from 250-503 m/s and 30 min to 2 hours. During recovery phase, poleward TIDs fall under the category of medium scale. In the American sector, the majority of poleward TIDs occurred during the storm's main phase, as opposed to the African-European sector, which experienced a significant number of poleward TIDs during the recovery phase. The periods and horizontal velocities of TIDs range from 45 min-1.5 h and 180-296 m/s during main phase. During the recovery phase, the horizontal velocity and period range from 177-271 m/s and 40-1.5 h, respectively. Overall, it has been shown that statistically, changes in equatorial electrodynamics related to enhanced eastward electric _eld and hence increased equatorial electrojet (vertical E_B drift) correlates highly with the reported poleward TIDs.]]> Sat 06 Apr 2024 13:06:52 SAST ]]> Economically important cephalopods of southern Angola, with a focus on the artisanal jig fishery https://vital.seals.ac.za/vital/access/manager/Repository/vital:71955 Sat 06 Apr 2024 12:42:05 SAST ]]> Prosecution of forced marriage by international courts and tribunals in light of the principle of legality https://vital.seals.ac.za/vital/access/manager/Repository/vital:71772 Sat 02 Mar 2024 08:27:50 SAST ]]> The proprietary consequences of foreign marriages for the purposes of estate planning and succession in South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:71773 Sat 02 Mar 2024 08:27:37 SAST ]]> Optimization of an intranasal levodopa nanocrystalline formulation for delivery to the brain https://vital.seals.ac.za/vital/access/manager/Repository/vital:71771 Sat 02 Mar 2024 08:09:23 SAST ]]> An in-depth investigation of an early literacy intervention in Grade R in the Eastern Cape Province, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:65844 Mon 17 Jul 2023 18:43:34 SAST ]]> Leveraging a peer-learning community and expert community members in the integration of indigenous knowledge into the learning and teaching of Grade 10 Chemistry on the rate of reactions https://vital.seals.ac.za/vital/access/manager/Repository/vital:65843 Mon 17 Jul 2023 18:30:32 SAST ]]> A Pedagogy of Love: reflections on 25 years of informal vocational education and training practices in the commercial fishing industry in South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:65841 Mon 17 Jul 2023 18:08:14 SAST ]]> Evaluating the trophic ecology and feeding habits of three divergent lineages of Sandelia bainsii (Teleostei: Anabantidae), from the Eastern Cape Rivers using stable isotope analysis https://vital.seals.ac.za/vital/access/manager/Repository/vital:65667 Mon 10 Jul 2023 19:25:05 SAST ]]> An appraisal analysis of a selection of Zapiro’s political cartoons https://vital.seals.ac.za/vital/access/manager/Repository/vital:70302 Mon 04 Dec 2023 18:09:09 SAST ]]>
