Weak gravitational lensing analyses of clusters of galaxies
(2011-04-04)
Comprising the most massive gravitationally bound and relaxed structures in the Universe, galaxy clusters are essential in providing a deeper understanding of the properties of dark matter. Being cosmologically young ...
Measuring cosmological weak lensing using the Advanced Camera for Surveys on board the Hubble Space Telescope
(2008)
Following from the theory of General Relativity, light-bundles are deflected and differentially distorted while passing through the gravitational potential of matter inhomogeneities. The gravitational lensing effect caused ...
Dark matter halos of galaxies studied with weak gravitational lensing
(2003)
The main goal of this thesis is to investigate the dark matter halos of galaxies. Current theories of galaxy formation predict that galaxies are embedded in large dark matter halos with much larger extents than the visible ...
