1. 1. A study of the gamma-ray emission from the blazar S50716+71 using the Fermi-LAT telescope

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

   Sammanfattning : This thesis sums up a bachelor project in which gamma-ray emission from an extra-galactic source (S50716+71) is studied using data collected by the Fermi Large Area Telescope (LAT). The emission consists of 12,5 years of data (April 2008 to February 2020) in the energy range 100 MeV - 300 GeV. LÄS MER

3. 2. Prompt emission in Gamma-ray bursts; Photospheric Radiation from Synchrotron-Like spectra

   Kandidat-uppsats, KTH/Fysik

   Författare :Erik Vitols; [2022]
   Nyckelord :Gamma-ray burst; radiation mechanisms: thermal and non-thermal;

   Sammanfattning : Gamma-ray bursts (GRBs) are the most luminous phenomena in the Universe, explosions whoseenergy is generated by supernovae or mergers of dense objects such as neutron stars. The GRBemission is divided into the prompt emission phase characterized by γ-ray radiation and the afterglowof lower energy radiation. LÄS MER
