1. 1. Analysis of Atmospheric Muon Bundles with IceCube

   Master-uppsats, Uppsala universitet/Högenergifysik

   Författare :Anna Selina Neyer; [2024]
   Nyckelord :;

   Sammanfattning : 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. 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

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

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

   Författare :Anton Holmberg; [2022]
   Nyckelord :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;

   Sammanfattning : 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.

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

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Manne Segerlund; [2021]
   Nyckelord :Supernova neutrinos; Supernova detection; Multi-messenger astronomy;

   Sammanfattning : 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.

7. 5. Ghosts of Our Past: Neutrino Direction Reconstruction Using Deep Neural Networks

   Kandidat-uppsats, Uppsala universitet/Högenergifysik

   Författare :Sigfrid Stjärnholm; [2021]
   Nyckelord :neutrino; neural network; ICECUBE; AI; convolutional neural network; CNN; askaryan emission; charged current; neutral current; CC; NC; Keras; TensoFlow; neutrino; neuralt nätverk; ICECUBE; AI; askaryan emission; Keras; TensorFlow;

   Sammanfattning : Neutrinos are the perfect cosmic messengers when it comes to investigating the most violent and mysterious astronomical and cosmological events in the Universe. The interaction probability of neutrinos is small, and the flux of high-energy neutrinos decreases quickly with increasing energy. LÄS MER
