Dynamical Studies of the Globular Cluster Systems around the Giant Elliptical Galaxies NGC4636 and NGC1399
(2011-08-02)
Dark matter studies in elliptical galaxies were long hampered by the lack of suitable dynamical tracers. The advent of 8 m-class telescopes equipped with multi-object spectrographs has made it possible to use globular ...
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.
Three introduction chapters about cosmology, gravitational ...

X-Ray Studies of Galaxy Clusters and Groups: Gas Properties in the Exceptional Cases of Faint Outskirts, High Redshift and a Merging Event
(2018-01-26)
The history and evolution of the universe, the understanding of the formation of structures and the investigation of a wealth of astrophysical phenomena are the topical subjects in present-day galaxy cluster physics and ......
