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 ...

Chemical Vapour Deposition Diamond: Charge Carrier Movement at Low Temperatures and Use in Time-Critical Applications
(2015-02-05)
Diamond, a wide band gap semiconductor with exceptional electrical properties, has found its way in diverse fields of application reaching from the usage as a sensor material for beam loss monitors at particle accelerator ...
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 ...
Galaxies in Milgromian Dynamics
(2015-02-04)
Since its first formulation in 1983, Milgromian dynamics (also known as modified Newtonian dynamics or MOND) has been very successful in predicting the gravitational potential of galaxies from the distribution of baryons ...
Mathesis of star formation – from kpc to parsec scales
(2015-06-16)
In this thesis I present a series of studies aiming to understand the formation of stars from gas in the Milky Way. Generally speaking, I will progress from larger to smaller scales.
The kilo-parsec scale (1000 ...

The Tagging System of the BGO-OD experiment
(2015-06-17)
In the course of my PhD work, I have been involved in the development and the construction of the Tagging System for the BGO-OD experiment at the ELSA accelerators of the University of Bonn.

Atomarer Transport und die Kontrolle von Transportresonanzen in optischen Gitterpotentialen
(2015-07-29)
Der Ratscheneffekt erlaubt es, eine gerichtete Teilchenbewegung mittels einer im zeitlichen Mittel ungerichteten Kraft zu erzeugen. Da die Transporteffizienz und die Transportrichtung eines klassischen Ratschensystems oft ...
Measurement of the top-quark mass and the ttZ cross section in ATLAS: the tt dilepton way
(2015-07-07)
A measurement of the top-quark mass and the ttZ cross section is performed using 4.6 fb-1 and 20.3 fb-1 of data from proton-proton collisions collected ...
Semileptonic Decays of Strange Beauty Mesons at Belle
(2015-07-16)
Semileptonic decays of b-flavoured mesons are an important tool for the determination of the CKM matrix element |Vcb|. In this thesis, measurements of semileptonic Bs meson decays ...
