Master thesis on the topic: Analysis of the Crab Nebula using Photon Stream Data observed by the First G-APD Cherenkov Telescope
In imaging air Cherenkov astronomy, the cosmic radiation is observed via the secondary particles it produces in Earth's atmosphere. These high-energy secondary particles cause the emission of Cherenkov light, which is measured by the Cherenkov telescopes' optical cameras. From this light, information on the cosmic radiation can be derived, to learn about the characteristics of the cosmic sources. The data, Cherenkov telescopes produce, consists of properties derived from the time series of measured voltages. These properties strongly depend on the detector's readout hardware. This work focuses on a new data representation, developed by Sebastian Mueller: the PhotonStream. It consists of single reconstructed photons and opens new possibilities for analyses throughout the field of Cherenkov astronomy. In this work, a first analysis of this new data representation is performed. To do so, openly accessible data of the First G-APD Cherenkov telescope is used. Alongside the results of origin reconstruction, gamma hadron separation and energy reconstruction, detailed investigations on the PhotonStream's properties and differences to the classical approach are presented.
