  1. 1. Measuring the vertical muon intensity with the ALTO prototype at Linnaeus University

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Magnus Norén; [2021]
    Nyckelord :Muon Intensity; ALTO; CoMET; Cosmic Rays; VHE Gamma Rays; Extensive Air Shower; Water Cherenkov Detector; Scintillation Detector; Monte Carlo Simulation; GEANT4;

    Sammanfattning : ALTO is a project, currently in the research and development phase, with the goal of constructing a Very High Energy (VHE) gamma-ray observatory in the southern hemisphere. It will detect the particle content reaching the ground from the interactions of either VHE gamma rays or cosmic rays in the atmosphere known as extensive air showers. LÄS MER

    Sammanfattning : This thesis describes a timing calibration method for the detector array of the ALTO experiment. ALTO is a project currently at the prototype phase that aims to build a gamma-ray astronomical observatory at high-altitude in the Southern hemisphere. LÄS MER

  4. 3. Dark Matter Signatures in Cosmic Gamma-Rays

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Jonas Wessén; [2012]
    Nyckelord :gravitino; 130 GeV line; IACT; MAGIC; indirect dark matter detection; decaying dark datter; Physics and Astronomy;

    Sammanfattning : This thesis concentrates on one of the indirect Dark Matter (DM) detection methods, namely through observations of Very High Energy (VHE) $\gamma$-ray signals from DM annihilation (or decay) in cosmic sources using the Imaging Atmospheric Cherenkov Technique (IACT). We discuss the particle physics and astrophysical aspects of those observations and perform several calculations which lead to an estimation of the DM detection prospects for IACTs. LÄS MER
