Galaxy and Mass Assembly (GAMA): Mid-infrared properties as tracers of galaxy environment
(EDP Sciences, 2023)We investigate how different mid-infrared (mid-IR) properties of galaxies are correlated with the environment in which the galaxies are located. For this purpose, we first study the dependence of galaxy clustering on the ... -
Galaxy And Mass Assembly (GAMA): Resolving the role of environment in galaxy evolution
(Oxford University Press, 2013)We present observations of 18 galaxies from the Galaxy And Mass Assembly (GAMA) survey made with the SPIRAL optical integral field unit (IFU) on the Anglo- Australian Telescope. The galaxies are selected to ... -
Galaxy And Mass Assembly (GAMA): spectroscopic analysis
(Oxford University Press, 2013)The Galaxy And Mass Assembly (GAMA) survey is a multiwavelength photometric and spectroscopic survey, using the AAOmega spectrograph on the Anglo-Australian Telescope to obtain spectra for up to _ 300 000 galaxies over ... -
Galaxy and mass assembly: evolution of the Hα luminosity function and star formation rate density up to z < 0.35
(OUP, 2013)Measurements of the low-z Hα luminosity function, Φ, have a large dispersion in the local number density of sources (∼0.5–1 Mpc−3 dex−1), and correspondingly in the star formation rate density (SFRD). The possible causes ... -
Galaxy cold gas contents in modern cosmological hydrodynamic simulations
(Oxford University Press, 2020-07-03)We present a comparison of galaxy atomic and molecular gas properties in three recent cosmological hydrodynamic simulations, namely SIMBA, EAGLE, and IllustrisTNG, versus observations from z ∼ 0 to 2. These simulations ... -
Galaxy correlations and the BAO in a void universe: structure formation as a test of the Copernican Principle
(IOP Science, 2013)A suggested solution to the dark energy problem is the void model, where accelerated expansion is replaced by Hubble-scale inhomogeneity. In these models, density perturbations grow on a radially inhomogeneous background. ... -
Galaxy training: A powerful framework for teaching!
(NLM (Medline), 2023)There is an ongoing explosion of scientific datasets being generated, brought on by recent technological advances in many areas of the natural sciences. As a result, the life sciences have become increasingly computational ... -
Galaxy–galaxy lensing in the voice deep survey
(EDP Sciences, 2022)The multi-band photometry of the VOICE imaging data, overlapping with 4.9 deg2 of the Chandra Deep Field South (CDFS) area, enables both shape measurement and photometric redshift estimation to be the two essential ... -
Galvanizing collective action to accelerate reductions in maternal and newborn mortality and prevention of stillbirths
(Johns Hopkins University, 2021)Every day, there are an estimated 810 maternal and 7,000 newborn deaths, and more than 5,000 stillbirths, most of which are preventable.1-3 While progress has been made in reducing maternal and neonatal morbidity and ... -
Gama/H-Atlas: The dust opacity-stellar mass surface density relation for spiral galaxies
(IOP Science, 2013)We report the discovery of a well-defined correlation between B-band face-on central optical depth due to dust and the stellar mass surface density of nearby spiral galaxies. This relation was derived from a sample of ... -
Gaussian process regression for foreground removal in hi intensity mapping experiments
(Oxford University Press, 2022)We apply for the first time Gaussian Process Regression (GPR) as a foreground removal technique in the context of single-dish, low redshift H I intensity mapping, and present an open-source PYTHON toolkit for doing so. We ... -
Gearing up for implementation: A new Children's Act for South Africa
(Taylor & Francis, 2008)The South African Government is presently processing a new comprehensive Children's Act, which is expected to be promulgated in 2008. The primary purpose of the Act is to give effect to the rights of children as contained ... -
Gelingualiseerde okklusie in die Suid-Afrikaanse konteks.
(2002)The search for the ideal artificial tooth arrangement that maximizes denture stability, comfort, aesthetics, and function has occupied the dental literature for many years and still continues to do so. Of the many occlusal ... -

Gender and participation: critical reflection on Zenzeleni Networks in Mankosi, South Africa
(ACM, 2016-11-25)This paper unveils the complexity of gender dynamics by reflecting on lessons learned in Zenzeleni Networks and provides a different perspective to notions of “participation” by asking “who participates and how?” The paper ... -
Gender and race distribution of dental graduates (1985 - 2004) and first year dental students (2000 - 2005) in South Africa
(South African Dental Association, 2005)This paper, written at the close of a decade of democracy in South Africa, sets out to analyse the demographic profile of dental graduates from 1985-2004 at the five Faculties/Schools of Dentistry in South Africa. A ... -
Gender construction in sexual offences cases: A case for fully reviving the Sexual Offences Courts
(Juta, 2020)Gender inequality, male hegemony and the power dynamics at the core of patriarchal society enable the high rate of sexual offences and the low conviction rate of sexual offenders when incidents are reported. The criminal ... -
