Aufbau eines Experiments zur Rückstreupolarisationsmessung an ELSA
(2015-05-05)
Das BGO-OD-Experiment am Bonner Elektronenbeschleuniger ELSA wurde für die Detektion von geladenen Teilchen unter kleinen Winkeln in Vorwärtsrichtung bei der Photoproduktion von leichten Mesonen an einem flüssigen ...
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 ...

R-Symmetries from the Orbifolded Heterotic String
(2014-11-20)
We examine the geometric origin of discrete R-symmetries in heterotic orbifold compactifications. By analysing the symmetries of the worldsheet instanton solutions and the underlying geometry, we obtain a scheme that allows ......
Development of pixel front-end electronics using advanced deep submicron CMOS technologies
(2014-10-17)
The content of this thesis is oriented on the R&D of microelectronic integrated circuits for processing the signal from particle sensors and partially on the sensors themselves. This work is motivated by ongoing upgrades ...
