Optical spectroscopy and applications of atomically precise graphene nanoribbons: from light emission to photodetection
(2020-11-16)
Atomically precise graphene nanoribbons (GNRs) are narrow stripes of graphene with a width of a few atoms and a well-defined edge structure. On-surface synthesis of GNRs from molecular precursors enables atomic precision ...
Photon Based Electron Beam Analysis at ELSA Utilizing Synchrotron Radiation and Compton Scattering
(2020-11-17)
Within the collaborative research center SFB/TRR 16 "subnuclear structure of matter" the beam diagnostic capabilities of the ELSA storage ring at the Physics Institute of Bonn University have been extended by a synchrotron ...
A 3-mm Imaging Line Survey of the Central Molecular Zones of M 82 and IC 342
(2020-07-07)
The central molecular zones of two nearby galaxies M 82 and IC 342 are among the most prominent extragalactic molecular sources in the northern hemisphere. While M 82 is a relatively small late type starburst galaxy, IC ...
Optimierung der GEM-basierten Verstärkungsstufe einer TPC für das CB/TAPS-Experiment
(2020-08-10)
Das CB/TAPS-Experiment widmet sich der Untersuchung des Spektrums angeregter Hadronen. In seinem aktuellen Aufbau ist es dabei auf die Identifikation und der Vermessung ungeladener Endzustände spezialisiert. In einer ...
Probing the Standard Model of particle physics with ttH, WWZ and WZZ multilepton final states
(2020-01-13)
The Standard Model of particle physics elegantly describes the fundamental constituents of matter and their interactions. The electroweak gauge and top-quark Yukawa couplings can be directly probed in the associated ...
Probing new physics with boosted H → bb decays with the ATLAS detector at 13 TeV
(2020-01-27)
The discovery of the Higgs boson by the ATLAS and CMS collaborations at the Large Hadron Collider was a major success in particle physics. Even though studies of the Higgs boson suggest that its properties are in agreement ......
Probing the Interstellar Medium and Dark Matter with Pulsars
(2020-03-05)
Pulsars are rapidly rotating, highly magnetised neutron stars which emit electromagnetic radiation from their magnetic poles in the form of highly collimated beams. Pulsars are known as a powerful tool to probe the ...
Hadron-Hadron Interactions from Nf = 2+1+1 Lattice QCD: The ρ-resonance
(2020-01-07)
In this work the calculation of the ρ resonance's decay parameters with Nf = 2+1+1 flavour lattice QCD is presented. The calculation is performed based on gauge configuration ensembles produced by the ETM ......
Disconnected Contributions to Hadronic Processes
(2020-01-06)
Lattice quantum chromodynamics (QCD) is a powerful tool to calculate the dynamics of low-energy, non-perturbative QCD. It has made great strides in numerically evaluating hadronic observables by simulating the interactions ...
Advanced Image Reconstruction Methods for Ultra-High Field MRI
(2020-07-07)
Magnetic resonance imaging (MRI) has become a very powerful and flexible medical imaging technique, that allows an unrivaled insight into human anatomy and physiology. For a wide range of possible applications, acquisition ...
