1. 1. Reconstruction of Radio Detector Data using Graph Neural Networks

   University essay from Uppsala universitet/Högenergifysik

   Author : Arnau Serra Garet; [2023]
   Keywords : ;

   Abstract : The current neutrino detectors have been able to detect neutrinos in the range of TeV to 100 PeV, however, ultra high energy (UHE) neutrinos above 100 PeV still remain to be detected. A new neutrino detector, the RNO-G, is currently being constructed in Greenland with the purpose of detecting the first UHE neutrinos using radio antennas capable of measuring the Askaryan pulse generated after a neutrino interaction with the ice molecules.

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

   University essay from Uppsala universitet/Högenergifysik
