Bachelor’s thesis: Multi-scale Clean in Radio Interferometric Imaging
This thesis examines the advantages of multi-scale clean as implemented in CASA‘s msclean over conventional (point source) clean algorithms when applied to THINGS.
Master’s thesis: Star Formation in the Galactic Center
My master’s thesis explains the steps of data reduction, imaging and ammonia hyperfine structure fitting of the Survey of Water and Ammonia in the Galactic Center (SWAG), and investigates gas kinematics and temperature of clouds in the Central Molecular Zone. It is found that they match the implications of the triggered star formation hypothesis of Longmore et al. (2013) and Kruijssen et al. (2015).
42 spectral lines were observed in SWAG and their images presented in appendix A. This heavily increases the file size to 46MB. The short version without App. A is much lighter at only 22 MB.

PhD thesis: Zooming into the Blast Furnace – A close look into the Molecular Gas in the NGC253 starburst
In my PhD thesis I study several aspects of the dense molecular gas in the center of the starburst galaxy NGC253. Parsec scale resolution ALMA data resolves the molecular outflow, allows to zoom into super star clusters and enables us to expand Galactic studies to nearby galaxies.
