Cosmological constraints from the power spectrum and bispectrum of 21cm intensity maps
(IOP Publishing, 2022)The 21cm emission of neutral hydrogen is a potential probe of the matter distribution in the Universe after reionisation. Cosmological surveys of this line intensity will be conducted in the coming years by the SKAO and ... -
Cosmological constraints on post-Newtonian parameters in effectively massless scalar-tensor theories of gravity
(2019)We study the cosmological constraints on the variation of Newton’s constant and on post-Newtonian parameters for simple models of the scalar-tensor theory of gravity beyond the extended Jordan-BransDicke theory. We restrict ... -
Cosmology from HI galaxy surveys with the SKA
(Proceedings of Science, 2014)The Square Kilometer Array (SKA) has the potential to produce galaxy redshift surveys which will be competitive with other state of the art cosmological experiments in the next decade. In this chapter we summarise what ... -
Cosmology on the largest scales with the SKA
(Proceedings of Science, 2014)The study of the Universe on ultra-large scales is one of the major science cases for the Square Kilometre Array (SKA). The SKA will be able to probe a vast volume of the cosmos, thus representing a unique instrument, ... -
Cosmology on ultralarge scales with intensity mapping of the neutral hydrogen 21 cm emission: limits on primodial non-gaussianity
(American Physical Society, 2013)The large-scale structure of the Universe supplies crucial information about the physical processes at play at early times. Unresolved maps of the intensity of 21 cm emission from neutral hydrogen HI at redshifts z ~ 1 − ... -
Cosmology with a SKA HI intensity mapping survey
(Proceedings of Science, 2014)HI intensity mapping (IM) is a novel technique capable of mapping the large-scale structure of the Universe in three dimensions and delivering exquisite constraints on cosmology, by using HI as a biased tracer of the ... -
Cosmology with Phase 1 of the Square Kilometre Array Red Book 2018: Technical specifications and performance forecasts
(Cambridge University Press, 2020)We present a detailed overview of the cosmological surveys that we aim to carry out with Phase 1 of the Square Kilometre Array (SKA1) and the science that they will enable. We highlight three main surveys: a medium-deep ... -
Cosmology with photometrically classified type IA supernovae from the SDSS-II supernova survey
(The American Astronomical Society, 2013)We present the cosmological analysis of 752 photometrically–classified Type Ia Supernovae (SNe Ia) obtained from the full Sloan Digital Sky Survey II (SDSS-II) Supernova (SN) Survey, supplemented with host–galaxy ... -
COSMOS2020: A panchromatic view of the universe to z ∼ 10 from two complementary catalogs
(University of the Western Cape, 2022)The Cosmic Evolution Survey (COSMOS) has become a cornerstone of extragalactic astronomy. Since the last public catalog in 2015, a wealth of new imaging and spectroscopic data have been collected in the COSMOS field. This ... -

Cost and cost-effectiveness of a parenting programme to prevent violence against adolescents in South Africa
(BMJ Publishing Group, 2019)This paper presents the costs and costeffectiveness of ‘Parenting for Lifelong Health: Sinovuyo Teen’, a non-commercialised parenting programme aimed at preventing violence against adolescents in low-income and middle-income ... -
The cost of caring : secondary traumatic stress and burnout among lay trauma counsellors in the Western Cape Province
(South African journal of psychology, 2020)The psychological and emotional risks associated with providing care to traumatized populations have been largely overlooked in the literature on non-professional trauma counselling in South Africa. Non-professional or lay ... -
Cost of Traditional Herbal Medicines for Noncommunicable Diseases in Rural and Urban Communities in South Africa
(Elsevier Inc., 2022)Objectives: This study assessed traditional herbal medicine (THM) and conventional medicine (CM) utilization among par- participants with a noncommunicable diseases in South Africa. Methods: A cross-sectional study of the ... -
Cost-benefit analysis of the common teaching platform for the undergraduate nursing degree programme in the Western Cape, South Africa
(LAM Publications Limited, 2014)Post-1994, the South African higher education sector underwent a number of reforms to address issues of inequalities, inefficiencies and fragmentation. Reform in the Western Cape Province included pooling the resources of ... -
A Cost-Effectiveness Analysis of a Home- Based HIV Counselling and Testing Intervention versus the Standard (Facility Based) HIV Testing Strategy in Rural South Africa
(PLOS ONE, 2015)Introduction There is growing evidence concerning the acceptability and feasibility of home-based HIV testing. However, less is known about the cost-effectiveness of the approach yet it is a critical component to guide ... -
Cost-effectiveness and efficacy of fluoride varnish for caries prevention in South African children: A cluster-randomized controlled community trial
(Wiley, 2021)Objectives: This cluster-randomized controlled community trial aimed to assess the efficacy and costs of fluoride varnish (FV) application for caries prevention in a high-risk population in South Africa. Methods: 513 ... -
Cost-effectiveness of the HiBalance training program for elderly with Parkinson’s disease: analysis of data from a randomized controlled trial
(SAGE Publications, 2018)OBJECTIVE: To determine the cost-effectiveness of the HiBalance training program for managing Parkinson’s disease (PD)-related balance and gait disorders. DESIGN: Cost comparison design following the randomized controlled ... -
Costs of implementing integrated community case management (iCCM) in six African countries: implications for sustainability
(Edinburgh University Global Health Society, 2017)BACKGROUND Sub–Saharan Africa still reports the highest rates of under– five mortality. Low cost, high impact interventions exist, however poor access remains a challenge. Integrated community case management (iCCM) was ... -
Coulomb excitation of 102 Ru with 12 C and 16 O
(American Physical Society, 2022)The Coulomb excitation of 102Ru was performed with beams of 12C and 16O ions. The beam particles scattered at forward angles were momentum analyzed with a magnetic spectrograph. The resolution achieved enabled the ... -
Coulomb excitation of and a change in structure approaching N = Z = 40
