I currently work on my PhD at the European Southern Observatory (ESO) where I study the interplay between large hot gas reservoirs within galaxy clusters -- known as the intra cluster medium (ICM) -- and the cold gas located in and around galaxies. In my thesis, I further explore non-conventional detection methods, such as Bayesian-forward-modelling techniques in the uv-plane, to analyze astrophysical processes associated with the ICM.
This work is a natural extension of the research done in my Master theses. There, I experimented with another non-conventional detection method, namely a matched filter applied in the uv-plane, that resulted in the first detection of HCO+(4-3) in a z>2 dusty star-forming galaxy. In my other Master thesis, I created toy models and mock observations of galaxy clusters based on the hydrodynamical simulation BAHAMAS. With these models and mock observations, I studied the effects of gas clumping in the ICM on the position of a galaxy cluster in the Luminosity-Halo mass relation.
All my studies allowed me to combine my brought astronomical interests -- from observational cosmology to high-resolution observations of the centres of galaxies -- with my technical programming skills I developed over the last few years.
