Tracing star formation in groups and filaments around a young active galaxy cluster at z ∼ 1.46.
(2022)Abstract available in PDF. -
The evolution of galaxies in Sunyaev-Zel’dovich selected galaxy clusters from ACT DR5.
(2023)Abstract available in PDF. -
Investigation of the South African public TVET colleges’ engineering official mathematics curriculum for entry level artisans.
(2023)One of the main objectives of any mathematics curriculum is to equip students with the necessary thinking skills for real-world problems. As the world evolves every day of our lives, so do the people living in it. ... -
New exact solutions for neutral and charged shear-free relativistic fluids.
(2022)We study shear-free gravitating fluids in general relativity. We first analyse the integrability of the Emden-Fowler equation that governs the behaviour of shear-free neutral perfect fluid distributions. We find a new ... -
Generalized radiating stellar models with cosmological constant and electric charge.
(2019)A general matter distribution, with the addition of the cosmological constant and electric charge, for the interior spacetime of a spherically symmetric radiating star undergoing gravitational collapse is considered in ... -
Hyperspheres of static charged fluids in standard and modified gravity.
(2019)Abstract available in PDF. -
Fixed point theory in various generalized metric-type spaces.
(2022)In the theory of fixed points, there are numerous articles dealing with generalization of the basic Banach contraction mapping principle. There has been two lines of approach. The first one is concerned with generalizations ... -
Probing the nature of dark energy with 21-cm intensity mapping.
(2020)Two approaches to measure the BAOs (baryon acoustic oscillations) with optical and radio telescopes, namely; galaxy redshift and intensity mapping (IM) surveys have been introduced and discussed in the literature. Among ... -
New models in general relativity and Einstein-Gauss-Bonnet gravity.
(2021)We generate the Einstein-Gauss-Bonnet field equations in five dimensions for a spherically symmetric static spacetime. The matter distributions considered are both neutral and charged. The introduction of a coordinate ... -
Role of Weyl tensor and spacetime shear in relativistic fluids.
(2021)The main gravitational theory in which we develop this work is general relativity. We study the role of the Weyl tensor in general relativistic fluid motion including the e↵ects of spacetime shear. Firstly we consider ... -
Using machine learning techniques to identify strong gravitational lensing systems in DES.
(2021)Gravitational lensing systems enable astronomers to look into the distant universe by magnifying distant objects. Strong gravitational lensing systems are an incredibly rare phenomenon, with only a total about 1; 000 ... -
Discontinuous Galerkin finite element method for the stokes problem using rectangular meshes.
(2020)Abstract available in PDF. -
Analysis of models arising from heat conduction through fins using Lie symmetries and Tanh method.

Epidemiological modelling of foot and mouth disease control in cattle: incorporating time and spatial spread of disease dynamics.
(2019)Foot and mouth disease (FMD) is a contagious animal viral infection that can spread rapidly if the disease is not monitored and controlled. Therefore, protecting livestock and controlling foot and mouth disease is important ... -
A numerical study of heat and mass transfer in non-Newtonian nanofluid models.
(2019)A theoretical study of boundary layer flow, heat and mass transport in non-Newtonian nanofluids is presented. Because of the diversity in the physical structure and properties of non-Newtonian fluids, it is not possible ...
