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 ...
Challenges of theoretical and numerical structure formation in a ΛCDM universe
(2015-06-22)
Systematic surveys of the extra-galactic sky have revealed the existence of large-scale structures in the Universe: the galaxy distribution is organized in a complex network of filaments surrounding underdense regions and ...
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.
