Radio-optical analysis of extended radio sources in the first look survey field
(2010)
I combine 610 MHz Giant Metrewave Radio Telescope (GMRT) data, 1.4 GHz Very
Large Array (VLA) data and 1.4 GHz Westerbork Synthesis Radio Telescope (WSRT)
observations, encompassing a ∼ 4 square degree field (sq. deg. ...
Infrared-bright galaxies in the millennium simulation and Sunyaev Zeldovich effect contamination
(2010)
Measuring the evolution of the abundance of galaxy clusters puts constraints on cosmological parameters like the cosmological density parameter m, σ8 and the dark energy equation of state parameter, w. Current observations ...
Modelling radio galaxies in the Millennium simulation: SKA/MeerKAT sources and CMB contaminants
(University of the Western Cape, 2010)
We investigate the modelling of radio galaxies within a semi-analytic framework in the Millennium Simulation of the Virgo Consortium. The aim is to assess the radio sources contamination of Sunyaev-Zeldovich (SZ) signatures ...
Stellar masses of star forming galaxies in clusters
(University of the Western Cape, 2010)
We determine the stellar mass of star forming galaxies in the X-ray luminous cluster MS 0451.6-0305 at z ∼ 0.54. The stellar masses are estimated from fitting model spectral energy distributions (SEDs) to deep, optical ...
Luminous red galaxies in simulations
(2010)
There have been a number of attempts to measure the expansion rate of the Universe using age-dating of Luminous Red Galaxies (LRGs).Assuming stars in LRGs form at the same time, age-dating of two populations of LRGs at ...
Radon escape from water
(University of the Western Cape, 2010)
This thesis aims to measure the rate of radon loss from water in a systematic way. The dependence on surface area, temperature and concentration will be investigated. The experiments were done at UWC by creating radon using ...
Study of magnetic properties of nanostructures on self-assembled patterns
(University of the Western Cape, 2010)
In the current study, we give a report when oxalic acid was used as an electrolyte to synthesize an AAO template with hexagonal pore array. Optimum parameters were observed as 0.4 M of oxalic acid, anodizing voltage of 45 ...
Three dimensional thermal modelling of high temperature proton exchange membrane fuel cells in a serpentine design
(University of the Western Cape, 2010)
The aim of my work is to model a segment of a unit cell of a fuel cell stack using numerical methods which is classified as computational fluid dynamics and implementing the work in a commercial computational fluid dynamics ...
Ion genaration, deflection and deposition in vacuum
(University of the Western Cape, 2010)
In the PBMR it is known that at high temperatures (above 1250 'C) silver-110m is known to have been released from the TRISO particles and taken up by the helium coolant stream. The released silver-ll0m travels with the ...
