Cosmic Shear Analysis of the Garching-Bonn-Deep Survey
Hetterscheidt, Marco (2007)We perform a cosmic shear analysis of 15 square degree high-quality R-band data of the Garching-Bonn Deep Survey (GaBoDS) obtained with the Wide-Field-Imager (WFI) at the ESO/MPG 2.2m telescope. The GaBoDS comprises 1.75 ... -
Early Nucleosynthesis Studies with Quasar Absorption Line Spectroscopy
Erni, Peter (2007)Studying the light of celestial objects in different wavelengths is a fundamental approach and very common in astronomy, where large ground based telescopes and sophisticated high-resolution spectrographs became recently ... -
Old Globular Clusters in Dwarf Irregular Galaxies
Georgiev, Iskren Y. (2008)One of the most pressing questions in astrophysics to date is resolving the history of galaxy assembly and their subsequent evolution. In the currently popular hierarchical merging” scenario, massive galaxies are believed ...

RR Lyrae Sterne: Eigenschaften und Kinematik der RR Lyrae Sterne im Feld der Milchstraße
Maintz, Gisela (2008)Die vorliegende Arbeit befaßt sich mit RR-Lyrae-Sternen (RR Lyrs). Dabei werden die RR Lyrs in zweierlei Hinsicht betrachtet, nämlich sowohl in ihrer Kinematik in der Milchstraße als auch in ihren physikalischen Eigenschaft ...

Satellite Galaxies in the Local Group: CDM subhaloes or Tidal Dwarf Galaxies?
Metz, Manuel (2008)We use the Local Group satellite galaxies as probes of dwarf galaxy formation processes within the framework of the hierarchical structure formation theory. As the Local Group dwarf galaxies are not unambiguously verified ...

Simultaneous multichannel photometry with BUSCA
Cordes, Oliver-Mark (2004)This thesis deals with the multicolour simultaneous camera BUSCA (Bonn University Simultaneous CAmera), which was build at the Sternwarte of the University of Bonn for the the 2.2m telescope at the Calar Alto Observatory ... -
Small-scale studies of the Milky Way disc and halo gas with absorption-line spectroscopy
Nasoudi Shoar, Soroush (2012-12-13)Progressive studies in the last decades have shown that the interstellar medium (ISM) is more complex and dynamic than previously thought. The presence of the small-scale structures, structures on scales below 1 pc, has ...
