The Inner Galaxy in High Energy Gamma-rays
When High Energy Gamma-rays hit the atmosphere of the Earth, a shower of particles is produced until all of the energy is deposited. The particles in the shower produce Cherenkov light, which can be detected by telescopes on the ground. The Cherenkov Telescope Array (CTA) will be the next generation of Imaging Atmospheric Cherenkov Telescopes (IACTs), it is still under development. The H.E.S.S. telescope array is an IACT currently operating.
One part of my Ph.D. project is to work on ctapipe, which is an analysis software package for CTA, and to adapt it for the analysis of data from H.E.S.S. I will implement and improve different parts of the code such as e.g. background rejection, energy reconstruction or dealing with pixel saturation. After completion, I will use ctapipe to analyze data from H.E.S.S. of the inner galaxy.
Another part will be to work with the software GAMERA, which is used to model spectra and their time evolution of different particle distributions. I will include some new features to GAMERA such as diffusion and I will develop the implementation of anisotropic inverse Compton scattering further. GAMERA will be used later to model the data from H.E.S.S. of different sources in the inner Galaxy, which I analyzed with ctapipe before.
