Circumbinary disk simulations


I simulate the gas disk of a binary star system to investigate temperature distributions and compare them to the specific physical system IRAS 16293-2422 A. I run a parallelized, static mesh refined simulation of the system using the magnetohydrodynamics code Athena++. To identify the relevant physical processes to be included in the simulation, I have adapted the original code to the specific needs. I have learned a lot about numerical solvers and mesh refinement. I run the code on the institute cluster with Slurm. The output of the simulation then has to be analysed and visualised, for which I use Python specific tools.

Background event classification for Belle II


In this project I used neural networks to classify EvtGen simulated data into signal, \(B \to K^* \nu \bar{\nu} \), and background. The goal was to investigate the possibility of bypassing the expensive Geant4 detector simulation and following analysis. This...

CP violation in charmless B meson decays at the LHCb


Following in the footsteps of the LHCb collaboration, I worked on a project to validate the discovered evidence for CP violation in charmless, B meson decays. I developed a data analysis framework using ROOT to analyse the experimental data obtained...
