  1. 1. Analysis of Atmospheric Muon Bundles with IceCube

    University essay from Uppsala universitet/Högenergifysik

    Author : Anna Selina Neyer; [2024]
    Keywords : ;

    Abstract : This work is a preliminary study of the background of a search for dark, long-lived particles in the IceCube detector. The high flux of atmospheric muons in IceCube is considered background to the detector's primary science goal, which is to detect astrophysical neutrinos through the emission of Cherenkov radiation.

  3. 2. Assessment of Modern Statistical Modelling Methods for the Association of High-Energy Neutrinos to Astrophysical Sources

    University essay from KTH/Matematisk statistik

    Author : Valentin Minoz; [2021]
    Keywords : Statistics; Astrophysics; Neutrino sources; Mixture models; Monte Carlo methods; Maximum likelihood estimation; Statistik; Astrofysik; Neutrinokällor; Blandningsmodeller; Monte Carlo-metoder; Maximum likelihood-metoden;

    Abstract : The search for the sources of astrophysical neutrinos is a central open question in particle astrophysics. Thanks to substantial experimental efforts, we now have large-scale neutrino detectors in the oceans and polar ice. READ MORE

  4. 3. Neutrino oscillations at very high energy/matter density

    University essay from KTH/Fysik

    Author : Mathilde Guillaud; [2020]
    Keywords : Theoretical Physics; Neutrino Oscillations; Astrophysical Neutrinos; Teoretisk fysik; Neutrinooscillationer; Astrofysiska neutriner;

    Abstract : Neutrino oscillations in matter can be studied in different regimes, depending on the energy of the incoming neutrinos and the matter density of the medium. In this thesis we investigate neutrino oscillations in dense matter at very high energy (TeV-PeV range), taking into account the absorption that the neutrinos may undergo in such dense media.

  5. 4. A search for a prompt atmospheric muon neutrino flux in the northern hemisphere using data releases from IceCube

    University essay from Uppsala universitet/Högenergifysik

    Author : Marcus Haberland; [2020]
    Keywords : IceCube; flux; neutrinos; neutrino; muon neutrinos; muon neutrino; prompt; astrophysical; student project; contribution; fitting;

    Abstract : The IceCube Neutrino Observatory is a cubic kilometre scale detector for high-energy neutrinos above hundreds of GeV produced in Earth’s atmosphere as well as outside our solar system whenever particles are accelerated to ultra-relativistic energies. The prompt atmospheric contribution is a result of the creation of heavy mesons with charm components in the atmosphere. READ MORE

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

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

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

    Abstract : 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. READ MORE
