Study of two radio gravitational lenses: insight into the high-redshift Universe and properties of mass distribution
(2011-10-11)
Similarly to a magnifying glass, a gravitational field deflects light rays that travel through it. This phenomenon, predicted by the theory of General Relativity by A. Einstein (1915), is referred to as gravitational ...
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 ...
