(Elsevier, 2020-05)Please read abstract in the article.
-
(Oxford University Press, 2020-11)Although radio relics are understood to originate in intracluster shock waves resulting from merger shocks, the most widely used model for describing this (re-)acceleration process at shock fronts, the diffusive shock ...
-
(Elsevier, 2019-11)In this work, Schottky diodes based on undoped and (Ce, Al) co-doped ZnO thin films have been fabricated using the sol-gel spin coating. The effect of (Ce, Al) co-doped ZnO films on the structural and optical properties ...
-
(Elsevier, 2019-12)The spin-coating technique was utilized to produce thin films of nickel oxide on glass substrates. Three drying temperatures, 160 °C, and 200 °C, and 250 °C were used. Annealing temperatures ranged from 300 °C to 600 °C. ...

(Elsevier, 2019-11)Schottky diodes based on ZnO nanorods, undoped and co-doped with different concentrations (0.0, 0.2, 0.4, 0.6 and 0.8 at.%) of Ce and Sm, were fabricated on glass and on n-Si (111) substrates using chemical bath deposition ...

An insight into the extragalactic transient and variable microJy radio sky across multiple decades (Oxford University Press, 2019-12)The mJy variable extragalactic radio sky is known to be broadly non-changing with approximately 3 per cent of persistent radio sources exhibiting variability that is largely active galactic nucleus-related (AGN). In the ...

(Nature Publishing Group, 2010-11)Exciting opportunities are emerging for science and scientists in Africa. There is a vast pool of latent talent that can be a vital source of advancement and cooperation that has the potential to overcome barriers within ...
-
(EDP Sciences, 2021-04)We present MeerKAT neutral hydrogen (H i) observations of the Fornax A group, which is likely falling into the Fornax cluster for the first time. Our H i image is sensitive to 1.4 × 1019 atoms cm−2 over 44.1 km s−1 , ...
-
(Oxford University Press, 2022-05)We present MeqSilhouette v2.0 (MeqSv2), a fully polarimetric, time-and frequency-resolved synthetic data generation software for simulating millimetre (mm) wavelength very long baseline interferometry (VLBI) observations ...

-
(Oxford University Press, 2021-02)After a decade of design and construction, South Africa’s SKA-MID precursor MeerKAT has begun its science operations. To make full use of the widefield capability of the array, it is imperative that we have an accurate ...
-
(Oxford University Press, 2020-07)We propose a probabilistic framework for performing simultaneous estimation of source structure and fringe-fitting parameters in very long baseline interferometry (VLBI) observations. As a first step, we demonstrate this ...

(Wiley, 2012-04)About 200 coloured glass beads (red, yellow, green, blue, white, black, pink, plum) excavated on Mapungubwe hill and at K2, archaeological sites in the Limpopo valley South Africa, were studied with Raman scattering. This ...
