Exploring Radio Pulsars With New Technologies
(2017-04-03)
Pulsars are rapidly-rotating, highly-magnetized compact neutron stars. Their strong gravitational and magnetic fields, together with the stability of their rotations and the precision with which we can measure them using ...
Wave dynamics in random, absorptive or laseractive media
(2017-02-08)
We consider the behavior of light propagating in dielectrically disordered and energetically nonconservative material. Disorder and energy nonconservation can be dealt with via the use of the mathematical formalism commonly ...
Formation of low-mass helium white dwarfs orbiting binary millisecond pulsars
(2017-04-25)
Millisecond pulsars (MSPs) belong to a class of radio pulsars characterized by high rotational spin rates and low magnetic fields. These neutron stars are believed to be the end-product of binary evolution, in which an old ...
Comparing galaxy-galaxy(-galaxy) lensing in semi-analytic models and observations to study galaxy evolution
(2017-03-10)
One of the main challenges in cosmology is to understand the properties of dark matter, its distribution in the Universe, and its connection with baryonic matter. An ideal method to study the relation between baryonic ...
Kaon Fragmentation Functions From Semi-Inclusive Deep Inelastic Scattering of Muons on an Isoscalar Target
(2017-03-10)
This thesis presents the analysis of K0s multiplicities from COMPASS 2006 data, and the extraction of kaon fragmentation functions (FFs) including fits to K+ and K- multiplicities ...
Erzeugung eines Bose-Einstein-Kondensats aus Erbiumatomen in einer quasi-elektrostatischen Dipolfalle
(2017-03-02)
Ultrakalte Gase dienen seit den Achtzigerjahren der Erforschung neuartiger physikalischer Phänomene, in deren Rahmen zum Beispiel erstmals die Realisierung atomarer Bose-Einstein-Kondensate sowie die quantenentarteter ...
Møller polarimetry for the BGO-OD experiment and cross section measurement of the reaction γp → K+Λ at the extreme forward angles
(2017-01-24)
The BGO-OD experiment, located at the electron accelerator ELSA at the University of Bonn, is designed to study nucleon and hyperon excitations via meson photoproduction using an energy tagged bremsstrahlung photon beam, ...
Search for Supersymmetry with Hadronically and Leptonically Decaying Tau Leptons at the ATLAS Experiment
(2017-01-20)
The search for physics beyond the Standard Model (SM) is a central focus of modern particle physics. Supersymmetric extensions (SUSY) to the SM offer elegant solutions to many unresolved questions of the theory. This thesis ...
The Quantum Walk Microscope
(2017-03-02)
In this thesis, I present single-site detection of neutral atoms stored in a three-dimensional optical lattice using a numerical aperture objective lens (NAdesign = 0.92). The combination of high-resolution ......
MR-Phasenbilder ultraschallinduzierter Verschiebungsfelder an Brustläsionen
(2017-09-15)
In dieser Arbeit wurde eine Methode erforscht, die die Uktraschalstrahlungskraft mit der MRT kombiniert.
Durch die Schallstrahlungskraft werden im Gewebe Verschiebungen hervorgerufen. Diese lieferten einen Kontrast ...
