The curious case of offset bars : markers for a baby galaxy disk or signposts of an interaction with dark matter sub halos?
(University of the Western Cape, 2016)We have used the Spitzer Survey of Stellar Structure in Galaxies (S⁴G) as a representative sample of the local universe (total of 2352 galaxies in S⁴G) to make a catalog of offset disk barred galaxies. Using the combined ... -
The effects of environment on radio-loud AGN activity in Stripe 82
(University of the Western Cape, 2016)We investigate the link between environment and radiative accretion efficiency using a sample of 8946 radio-loud AGN detected at 1 − 2 GHz in the SDSS Stripe 82 region. We quantify their environments using the surface-density ... -
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 ... -
A multi-scale study of the star formation law in nearby galaxies
(University of the Western Cape, 2020)This research aimed to evaluate the effects of changing length-scales on the star formation laws and star formation efficiencies for our selected sample of galaxies. We have combined high-resolution Hi data from The Hi ... -
The nature of the microjy source population
(University of the Western Cape, 2015)The study of the faint radio universe and of its properties has recently become a very active field of research not only because of the much improved capabilities of the SKA pathfinders but also because of the need to ... -
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 ... -
A study of the angular momentum content of early-type galaxies
(University of the Western Cape, 2019)
