Central stellar populations of brightest cluster galaxies
(South African Institute of Physics, 2014)We analyse the stellar populations of a sample of brightest cluster galaxies (BCGs), for which high signal-to-noise ratio, long-slit spectra were obtained on the Gemini telescopes, by fitting their spectra using the software ... -
The central stellar populations of brightest cluster galaxies
(North-West University, 2012)The majority of galaxy clusters contain a massive galaxy in the centre of the clusters that are far more luminous and massive than the other galaxies in the cluster. These galaxies are called the brightest galaxy clusters ... -
Central systolic pressure and a nonessential amino acid metabolomics profile: the African prospective study on the early detection and identification of cardiovascular disease and hypertension
(Wolters Kluwer, 2019)Objectives: Early-life exposures to cardiovascular risk factors may manifest as early vascular ageing, a phenomenon to which black populations are more prone. The metabolome provides insight into the current state and ... -
A centralised data management system for the South African mining and industrial sectors
