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 ......
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 ...
New Insights into the Milky Way Magnetic Fields through Radio Broadband Spectro-polarimetry
(2020-03-05)
Magnetic field is an essential ingredient of the interstellar medium of galaxies. In particular, an accurate characterisation of the magnetic field strength and structure of the Milky Way is crucial for complete understanding ...
Halo bias renormalisation
(2020-06-09)
Modern galaxy redshift surveys provide a wealth of information about the evolution of our Universe. They allow to measure both the two-dimensional position on the sky and the distance (given by the cosmological redshift) ...
Radio Continuum of Galaxies with H2O-Megamaser-Disks
(2019-11-08)
Galaxies with H2O-megamaser-disks are low luminosity active galaxies where 22GHz H2O-maser emission is detected in their accretion disk surrounding the central supermassive black hole (SMBH). Furthermore, ...
Molecular gas in hydrodynamical simulations of galaxy formation
(2022-09-26)
Observations of nearby galaxies indicate a strong correlation between their molecular gas content and their star formation rate. This leads to the conclusion that molecular hydrogen – the most abundant molecule in galaxies ...
Binary star population synthesis: Progenitors of gravitational wave driven mergers
(2018-06-13)
The vast majority of all massive stars are born in binaries. The binarity of a star may influence its life drastically via a large variety of interactions with its companion star. Several astrophysical events, like the ...
X-Ray Studies of Galaxy Clusters and Groups: Gas Properties in the Exceptional Cases of Faint Outskirts, High Redshift and a Merging Event
(2018-01-26)
The history and evolution of the universe, the understanding of the formation of structures and the investigation of a wealth of astrophysical phenomena are the topical subjects in present-day galaxy cluster physics and ......
GLOSTAR: Investigating Tracers of Early High-Mass Star Formation
(2023-05-12)
High-mass stars (>8 msol) are not as numerous as their less massive counterparts but have a much more profound impact on their environment within their native galaxies. Despite their importance, our understanding of their ...
