The 2023 dissertation prize was awarded to two people:
Dr. Ancla Müller and Dr. Jan Luca van den Busch
Polarized radio emission of cluster galaxies: clue to the physics of ram-pressure stripping and its influence on galaxy evolution
Dr. Ancla Müller
With the help of the uniquely deep observational data, Ms. Müller was able to map the magnetic field structure of star-forming galaxies in a galaxy cluster for the first time and thus draw conclusions about their evolution in such an environment, taking into account their magnetic properties. Furthermore, large-scale emissions could be mapped and the rarely observed re-acceleration processes could be studied.
A Study in Redshift - Simulating and calibrating cosmic shear surveys
Dr. Jan Luca van den Busch
The key to understanding our cosmos lies in the distribution of matter, which we reconstruct by observing millions of galaxies in extensive observation campaigns. A major challenge is to reconstruct the third dimension, the distance, from our two-dimensional view of the night sky. As part of his dissertation, Mr. van den Busch has tested and further developed the latest techniques for distance determination using realistic simulations. The results of this work are an important contribution to mastering the challenges of the future generation of observation campaigns.
