  1. 1. Fermi-LAT gamma-ray and multi-wavelength SED analysis and modelling of PKS 0426-380 : A thesis analysing the behaviour and properties of the blazar PKS 0426-380

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

    Författare :Nathanael Löfström; [2022]
    Nyckelord :active galactic nucleus; black hole; AGN; Fermi-LAT; JetSeT;

    Sammanfattning : An analysis is made on the Flat Spectrum Radio Quasar PKS 0426-380 using two sets of data. The first set of data is the Fermi-LAT data collected over the time 54682.66 − 59317.66 in Modified Julian Date within the energy range of 100 MeV to 500 GeV. LÄS MER

  3. 2. 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)

    Författare :Fredrik Vislander; [2022]
    Nyckelord :AGN; active galactic nuclei; Fermi-LAT; astrophysics; gamma-rays; synchrotron self-Compton; SSC; S50716 71.;

    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

  4. 3. Gamma-ray emission and Synchrotron Self-Compton modelling of the macrolensed Quasar PKS 1830-211

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

    Författare :Pierre Ohlsson; [2020]
    Nyckelord :Gamma-ray;

    Sammanfattning : The objective of this thesis is to retrieve Light Curves, Spectral Models, Spectral Maps, and to geta Spectral Energy Distribution (SED) plot, for the source of PKS1830-211. Finally, also to do amodelling of the whole SED coming from the source with the JetSet software. Which will then becompared to a previous modelling done by A. A. LÄS MER

  5. 4. Analysis of the Hard Spectrum BL Lac Source 1H 1914-194 with Fermi-LAT Data and Multiwavelength Modelling

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

    Författare :Dominic Gächter Sundbäck; [2018]
    Nyckelord :;

    Sammanfattning : The very-high-energy gamma-ray emission of the hard spectrum BL Lac source 1H1914-194 has been studied with Fermi-LAT data covering a nearly ten-year period between August 2008 until March 2018 in the energy range of 300 MeV to 870 GeV. The mean flux has been determined as 8.4 x 10-9±3.5 x 10-10 photon cm-2 s-1. LÄS MER

  7. 5. High energy gamma ray emission and multi-wavelength view of the AGN PKS 0537-441

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

    Författare :Emma Fransson; [2017]
    Nyckelord :astrophysics; AGN; PKS 0537-441; jet; accretion; synchrotron self compton; spectral energy distribution;

    Sammanfattning : This thesis describes the analysis of Very High Energy (VHE) emission from the Active Galactic Nucleus PKS 0537-441. It also aims to put the results in a wider context by implementing previous work done on this source. The data chosen for the analysis is provided by the Fermi-LAT satellite and covers the energy range between 300 MeV and 300 GeV. LÄS MER
