Studying Galaxy-Galaxy Lensing and Higher-Order Galaxy-Mass Correlations Using the Halo Model
(2009-06-22)
In recent years, the distribution of galaxies in the Universe could be measured up to large distances and over a significant part of the sky. The analysis of this large-scale structure contains a wealth of cosmological ...
A Tale of Two Wide Separation Gravitational Lenses
(2008)
Wide separation gravitational lens systems are good candidates to probe the matter (luminous+dark) distribution in massive halos. Investigation of two wide separation lens systems is carried out. MG 2016+112 is a quadruply ...
Application of photometric redshifts on the correlation properties of galaxies and matter
(2007)
In the past years cosmology, the science of the universe as a whole, has seen tremendous progress. The Lambda-Cold-Dark-Matter scenario is widely accepted as the standard model of cosmology describing the evolution of the ...
