  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

  2. 2. A gamma-ray study of a highly variable blazar : The Fermi-LAT analysis and the modeling of the FSRQ PKS 1510–089

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

    Författare :Nadja Bollström; [2021]
    Nyckelord :active galactic nuclei; AGN; astrophysics; jet; PKS 1510-089; Fermi; external Compton model; gamma-rays;

    Sammanfattning : The subject of this thesis is the analysis and modeling of the active galactic nucleus PKS 1510-089. The aim is to present a thorough background of active galactic nuclei combined with the analysis and modeling of a specific active galactic nucleus. The results will then be  linked to previous research and theories about active galactic nuclei. LÄS MER

  3. 3. Analysis of Mouse Whisker Movement Synchronicity

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Johanna Elisabeth de Voogel; [2020]
    Nyckelord :;

    Sammanfattning : In active sensing, sensory organs are actively controlled by the motor system to optimize stimuli acquisition. Coupling behaviour of animal models with electrophysiological signals could give us important insights in the workings of this active sensing in health and disease. In this work, a contribution is made towards this aim. LÄS MER

  4. 4. 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. 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
