Weak Lensing Mass Determination of Eight X-ray Selected Galaxy Clusters from the 400d Survey
(2011-01-19)
Evolution in the mass function of galaxy clusters sensitively traces both the expansion history of the Universe and cosmological structure formation. Hence, measuring the number density of galaxy clusters as a function of ...
Exploring Dark Matter Properties from the Smallest to the Largest Scales
(2004)
One of the main problems in cosmology is to understand the formation and evolution of galaxies, galaxy clusters, and large-scale structure. Whereas the basics of the current Cold Dark Matter (CDM) paradigm for structure ...
Weak lensing measurements for the APEX-SZ cluster survey
(2014-12-02)
The formation of structures in the universe, such as galaxy clusters, depends sensitively on cosmological parameters. Measuring the abundance of clusters as a function of mass and redshift therefore yields a way to constrain ...
Optical Data Analysis and its Application to Cosmology
(2016-03-30)
This work is concerned with different aspects of observational cosmology. It covers a broad range of problems that one needs to deal with in optical astronomy.
