The Radio Continuum Halos of the Edge-on Galaxies NGC 891 and NGC 4565
Schmidt, Philip (2016-10-13)The halos of spiral galaxies are complex entities consisting of multiple matter components, generally including neutral and ionized gas phases, cosmic rays (CRs), dust, as well as extraplanar stars. The detection of ... -
Radio Continuum of Galaxies with H2O-Megamaser-Disks
Kamali, Fateme (2019-11-08)Galaxies with H<sub>2</sub>O-megamaser-disks are low luminosity active galaxies where 22GHz H<sub>2</sub>O-maser emission is detected in their accretion disk surrounding the central supermassive black hole (SMBH). Furthermore, ... -
Radio Emission from Cosmic Ray Air Showers
Huege, Tim (2005)Charged particles with energies ranging from a few times 10<sup>6</sup> eV up to ≥ 10<sup>20</sup> eV continuously impinge on the earth as so-called “cosmic rays”. Their study constitutes an important field of research in ... -
Radio emission from massive Young Stellar Objects and their surroundings: Characterization and feedback
Serrano Medina, Sac Nicte Xiomara (2020-10-12)Massive stars or high-mass stars dominate their galactic environments. They play a major role in the energy budget of galaxies and are essential in their evolution. However, high mass star formation is not fully understood, ... -
A radio view on the structural evolution of massive star-forming galaxies across cosmic time
Jiménez-Andrade, Eric Faustino (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 ... -
Radiologische Detektion experimentell erzeugter Defekte im humanen Kieferknochen
Pieper, Christiane (2018-11-08)Defekte im humanen Kieferknochen entstehen durch entzündliche, zystische oder tumoröse Erkrankungen und entwickeln sich unterschiedlich schnell. Die korrekte und frühzeitige Diagnose ist äußerst relevant für die anstehende ... -
