1. 1. PERFORMANCE OF THE PHOTODETECTOR FOR THE ACTIVE SHIELD OF THE COSI SPACE TELESCOPE

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Daniel Álvarez Franco; [2022]
   Keywords : Geant4; scintillation; BGO; CsI; simulation; COSI; telescope; photoelectric effect;

   Abstract : The COmpton Spectrometer and Imager (COSI) is a space telescope that aims to study the soft gamma regime (0.2-5 MeV), capable of performing spectroscopy, imaging and polarimetry of cosmic gamma sources. READ MORE

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

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

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

   Abstract : 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. READ MORE

4. 3. Constraints on the High-Energy Gamma-Ray Spectrum of Nearby Star-Forming Galaxies

   University essay from Stockholms universitet/Fysikum

   Author : Oskar Svenborn; [2021]
   Keywords : Gamma-ray emission; High-Energy astrophysics; Star-Forming Galaxies; Star formation; Cosmic rays; Fermi-LAT.;

   Abstract : The nature of high-energy gamma-ray emission from Star-Forming Galaxies is of utmost importance for understanding both the origin of Cosmic Rays and the high-energy processes that shape galaxy formation. Observations from the gamma-ray telescope Fermi-LAT have detected gamma-ray emission from a handful of nearby Star-Forming Galaxies. READ MORE

5. 4. Test setup for LDMX HCal readout

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Joshua Greaves; [2020]
   Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

   Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

6. 5. ALTO Timing Calibration : Calibration of the ALTO detector array based on cosmic-ray simulations

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : Sotirios-Ilias Tsivras; [2019]
   Keywords : ALTO; Cosmic-Rays; Water Cherenkov Detector; Python;

   Abstract : 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. READ MORE
