Far-infrared-radio relations in clusters and groups at intermediate redshift
(University of the Western Cape, 2014)
In this thesis, we present a multi-wavelength analysis of star-forming galaxies to shed new light on the evolution of the far-IR-radio relations in intermediate redshift (0.3 < z < 0.6) galaxy clusters and galaxy groups. ...
Galaxy evolution and cosmology studies using luminous red galaxies
(University of the Western Cape, 2014)
There have been a number of attempts to measure the expansion rate of the Universe using age-dating of Luminous Red Galaxies (LRGs). Assuming that stars in LRGs form at the same time, age-dating of two populations of LRGs ...
Spectrally selective AlXOY/Pt/AlXOY solar absorber coatings for high temprature solar-thermal applications
(University of Western Cape, 2014)
The limited supply of fossil hydrocarbon resources and the negative impact of CO2 emission on the global environment dictate the increasing usage of renewable energy sources. Concentrating solar power (CSP) systems are the ...
