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 ...
Weak Lensing Flexion Study
(2010-09-01)
In this thesis, I studied the higher order weak gravitational lensing effect,flexion, and some of its potential applications in cosmology.
Flexion, as a new subject in lensing, has shown its advantages in various ...

Cosmic Shear and the Intrinsic Alignment of Galaxies
(2010-11-12)
Cosmology has recently entered an era of increasingly rich observational data sets, all being in agreement with a cosmological standard model that features only a small number of free parameters. One of the most powerful ...
Statistical properties of cosmological correlation functions
(2015-04-24)
Correlation functions are an omnipresent tool in astrophysics, and they are routinely used to study phenomena as diverse as the large-scale structure of the Universe, time-dependent pulsar signals, and the cosmic microwave ...
