  1. 1. Neutrino Hotspots in the Universe: a Sensitivity Study Using the IceCube Neutrino Observatory

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Kiana Ghiassi; Julia Salwén; [2023]
    Nyckelord :Astrophysics; Neutrino Astronomy; Particle Physics; Neutrinos; Blazars; Sensitivity Study; IceCube Neutrino Obesvatory;

    Sammanfattning : In this report, we aim to assess the sensitivity and 5$\sigma$ discovery potential of IceCube, the largest neutrino observatory on Earth, and compare it with prior findings. Our thesis will focus on a point source analysis, exploring the energy and declination dependencies, with particular emphasis on high-energy neutrinos. LÄS MER

  2. 2. AGN Candidates for High Energy Neutrino Emission in IceCube

    Master-uppsats, Uppsala universitet/Högenergifysik

    Författare :Roisín O'Rourke Brogan; [2020]
    Nyckelord :active galactic nuclei; agn; high energy physics; neutrinos; IceCube; blazars; jets; gamma emission;

    Sammanfattning : Since the construction of the IceCube Neutrino Observatory was completed in 2010, many amazing discoveries have been made in the field of neutrino physics. Recently a neutrino event has been linked to an blazar-type active galactic nucleus source, bringing us one step closer to understanding the production of high-energy extragalactic neutrinos and ushering in a new era of multimessenger astronomy.

  3. 3. High Energy gamma-ray behavior of a potential astrophysical neutrino source : The case of TXS 0506+056

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

    Författare :Nora Valtonen-Mattila; [2019]
    Nyckelord :Blazars; Active Galactic Nuclei; TXS 0506 056; Gamma rays; AGN; astrophysical neutrino; IceCube neutrino; astrophysical jets;

    Sammanfattning : Blazars are a type of Active Galaxy that emit strong astrophysical jets. The association of a HE gamma-ray flare from the blazar TXS 0506+056 to the IceCube-170922A neutrino event in 2017, opened the possibility to a link between these two events. LÄS MER
