Abstract
This work of thesis aims to investigate the process of dark matter (DM) annihilation in galaxy clusters (CG). In particular, the search for DM signal was conducted in the Perseus CG in the very-high-energy (VHE) -ray range. Using data of the Perseus CG collected by MAGIC (Major Atmospheric Gamma Imaging Cherenkov Telescopes), we analyze 45.1 h of data. The morphology of the cluster is taken into account by ad-hoc simulations using a method known as donut Monte Carlo (MC). In order to address properly this study for the annihilation case, J-factors were calculated and a surface brightness profile (SBP) of Perseus was created for this specific work. The annihilating DM J-factor (smooth component only considering spherical halo) calculated in this work is 8:72 1017GeV2cm􀀀5 as well as the decaying DM D-factor with value of 2:84 1018GeVcm􀀀2 and are used for morphology study. An investigation of the skymaps and 2 plots of the analysed sample is used to suppress the signal from the AGN (Active Galactic Nuclei) present in the centre of the field of view, NGC 1275. The applied set of cuts successfully excludes NGC 1275 from the data sample. Future prospects include the calculation of the sensitivity of the search and the estimation of the dark matter annihilation crosssection for different channels.
