The isotropy of the Universe as seen through galaxy clusters
(2021-07-07)
The cosmological principle (CP) postulates that the Universe is isotropic and homogeneous. This implies that the Universe has the same expansion rate toward every direction and holds similar amounts of matter when averaged ...
The physical and chemical conditions of molecular clouds on large scales
(2021-09-15)
Observations of molecular emission lines in the radio and (sub)millimetre wavelength regime provide insights into the interiors of molecular clouds which are inaccessible by other forms of radiation. Examining the physical ...
Understanding the impact of massive star formation on its surroundings in Messier 8
(2020-06-04)
Massive stars inject an immense amount of energy into their surroundings, which affect the physics and chemistry of the interstellar medium (ISM). Massive stars play a significant role in the evolution of galaxies. The ...
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 ...
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 ...
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 ...
