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. Fast Simulations of Radio Neutrino Detectors : Using Generative Adversarial Networks and Artificial Neural Networks

   University essay from Uppsala universitet/Högenergifysik

   Author : Anton Holmberg; [2022]
   Keywords : Askaryan emission; Radio detection of neutrinos; in-ice propagation; neutrino; Generative adversarial networks; GAN; WGAN; Neural networks; NN; surrogate model; IceCube; deep learning; generative model;

   Abstract : Neutrino astronomy is expanding into the ultra-high energy (>1017eV) frontier with the use of in-ice detection of Askaryan radio emission from neutrino-induced particle showers. There are already pilot arrays for validating the technology and the next few years will see the planning and construction of IceCube-Gen2, an upgrade to the current neutrino telescope IceCube.

4. 3. Birefringence: Effects and Implications on In-Ice Radio Detection of High-Energy Neutrinos

   University essay from Uppsala universitet/Högenergifysik

   Author : Nils Heyer; [2022]
   Keywords : Birefringence; Cosmic Neutrinos; In-ice radio propagation;

   Abstract : The detection of high-energy neutrinos in the EeV range requires new detection techniques to cope with the small expected flux. The radio detection method, utilizing Askaryan emission, can be used to detect these neutrinos in polar ice. READ MORE

5. 4. 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

6. 5. Estimating progenitor mass and distance to Galactic Core-Collapse Supernova using neutrino observatory IceCube

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Manne Segerlund; [2021]
   Keywords : Supernova neutrinos; Supernova detection; Multi-messenger astronomy;

   Abstract : Galactic core-collapse supernovae is a once-in-a-lifetime event which could carry with it information about new physics. In this work a method for estimating the progenitor mass and distance using the IceCube Neutrino Observatory is presented. The mass is expressed through an intermediate parameter called compactness.
