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 ... -
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 ... -
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 ...
