A radio view on the structural evolution of massive star-forming galaxies across cosmic time
(2020-03-06)
It is not well understood what processes regulate the global formation of stars in galaxies throughout cosmic history. My work aims to measure the structural evolution of star-forming galaxies (SFGs), from the present back ...
Die Implementierung des Themas Fernerkundung in den Schulunterricht der Sekundarstufe I durch das neue MINT-Wahlpflichtfach "Geographie-Physik": eine Studie zur praktischen Schulfachgestaltung im Differenzierungsbereich der Jahrgangsstufen 8 und 9 an Gymnasien in Nordrhein-Westfalen am Beispiel des Gymnasiums Siegburg Alleestraße
(2021-10-26)
Schülerinnen und Schüler werden in ihrer Alltagswelt seit dem letzten Jahrzehnt immer früher mit Satellitenbildern konfrontiert. Durch den Wetterbericht und die Nachrichtensendung im Fernsehen oder durch virtuelle Globen ...
Probing the Magnetized Medium of Galaxies and AGNs using Wideband Radio Polarimetry
(2019-08-13)
I performed an observational study of diffuse linearly polarized synchrotron emission of a nearby galaxy and of extragalactic background sources in order to study cosmic magnetism. The speciality of my work is given by the ......
Small Molecules, Big Impact: Investigating Hydrides in the Interstellar Medium
(2021-06-16)
This thesis investigates hydride molecules in the interstellar medium (ISM) and their use as diagnostics of different phases of the ISM. Particular emphasis is given to the central CH radical, a probe of diffuse and ......
Pulsar searching with the Effelsberg telescope
(2020-02-21)
Pulsars, highly magnetised rapidly-rotating neutron stars, have proved themselves to be incredible tools for exploring many aspects of fundamental physics and astrophysics. More opportunities for building new theories and ...
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 ...
Weak lensing magnification in SpARCS
(2020-02-04)
The growth of large scale structure is one of the fundamental predictions of any cosmological model. Galaxy clusters are the highest peaks in the cosmological matter density field and therefore of prime importance in ...
Complex organic chemistry in high-mass star forming regions
(2019-10-22)
The quest for interstellar complex organic molecules (COMs) lies at the heart of astrochemistry. One basic motivation is to figure out how the rich inventory of COMs found in meteorites and comets is connected to interstellar ...
Cosmology with the galaxy bispectrum
(2019-10-29)
The last decades witnessed huge progress in understanding the large-scale structure of the Universe. While homogeneous and isotropic on the largest scales, the matter and galaxy distributions display complex patterns on ...
Targeted Fast Radio Burst Searches with the Efflesberg 100-m Radio Telescope
(2021-03-24)
Fast radio bursts (FRBs) are bright, energetic, millisecond duration radio bursts of extragalactic origin. The source of FRBs still remains an open problem. Since the discovery of FRBs in 2007, over 100 FRBs have been ...
