Pulsations and eclipse-time analysis of HWVir
(Oxford University Press, 2018)
We analysed recent K2 data of the short-period eclipsing binary systemHWVir,which consists
of a hot subdwarf-B type primary with an M-dwarf companion.We determined the mid-times
of eclipses, calculated O–C diagrams, and ...
Properties of submillimeter galaxies in the CANDELS GOODS-south field
(American Physical Society, 2014)
We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field. The galaxies were first identified as submillimeter sources with the LABOCA bolometer and subsequently targeted ...
A deep search for faint galaxies associated with very low-redshift C iv absorbers: A case with cold-accretion characteristics
(The American Astronomical Society, 2013)
Studies of QSO absorber–galaxy connections are often hindered by inadequate information on whether faint/dwarf
galaxies are located near the QSO sight lines. To investigate the contribution of faint galaxies to QSO ...
Forming the Moon from terrestrial silicate-rich material
(Elsevier, 2013)
Recent high-precision measurements of the isotopic composition of lunar rocks demonstrate that the bulk
silicate Earth and the Moon show an unexpectedly high degree of similarity. This is inconsistent with one
of the ...
Isothermal dust models of Herschel-ATLAS galaxies
(Oxford University Press, 2013)
We use galaxies from the Herschel-ATLAS survey, and a suite of ancillary simulations based on an isothermal dust model, to study our ability to determine the effective dust temperature, luminosity and emissivity index of ...
High-Precision Branching Ratio Measurement for the Superallowed + Emitter 74Rb
(American Physical Society, 2013)
A high-precision branching-ratio measurement for the superallowed β
+ decay of 74Rb was performed at the
TRIUMF Isotope Separator and Accelerator (ISAC) radioactive ion-beam facility. The scintillating electronpositron
tagging ...
Calibrating photometric redshifts with intensity mapping observations
(American Physical Society, 2017)
Imaging surveys of galaxies will have a high number density and angular resolution yet a poor
redshift precision. Intensity maps of neutral hydrogen (HI) will have accurate redshift resolution
yet will not resolve ...
Bringing together knowledge and capabilities: a case study of engineering graduates
(Springer Verlag, 2016)
In contemporary times there is a renewed focus on the purposes of university
education in science or engineering, especially inemerging economycontexts like South Africa
where the massification of higher education is in ...
Mufasa: The assembly of the red sequence
(Oxford University Press, 2017)
We examine the growth and evolution of quenched galaxies in the Mufasa cosmo-
logical hydrodynamic simulations that include an evolving halo mass-based quench-
ing prescription, with galaxy colours computed accounting ...
News from the EREBOS project
(De Gruyter Open, 2017)
Planets and brown dwarfs in close orbits will interact with their host stars, as soon as the stars evolve to become
red giants. However, the outcome of those interactions is still unclear. Recently, several brown dwarfs ...
