1. 36. 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. 37. Constraints on the Kaluza-Klein Photon as a Dark Matter Candidate from the IceCube Collaboration Results

   L3-uppsats, Uppsala universitet/Högenergifysik

   Författare :Miquel Colom i Bernadich; [2019]
   Nyckelord :dark matter; WIMP; Kaluza-Klein; IceCube; neutrinos; muon neutrinos; muons;

   Sammanfattning : New constraints on the scattering cross sections of the Kaluza Klein photon as a darkmatter candidate, its annihilation rate in the Sun and the resulting muon flux on Earth are derived.For this purpose, data collected in the IceCube Neutrino Observatory during 532 days of exposurein the austral winters between 2011 and 2014 have been analyzed with Poisson confidence intervals (J.

4. 38. MAC-E-Filter characterization for PTOLEMY : a relic neutrino direct detection experiment

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Carl-Fabian Strid; [2019]
   Nyckelord :particle physics; astroparticle physics; astrophysics; PTOLEMY; relic neutrinos; monte carlo simulation; mac-e-filter; sterile neutrinos; physics beyond the standard model;

   Sammanfattning : The cosmic neutrino background (CNB) can be composed of both active and hypothetical sterileneutrinos. At approximately one second after big bang, neutrinos decoupled from radiationand matter at a temperature of approximately one MeV. LÄS MER

5. 39. Potential of harvesting solar neutrinos to power electric cars

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Michael Hoenes; [2019]
   Nyckelord :;

   Sammanfattning : Imminent penalties for excess emissions force the automotive industry to radically rethink how to power vehicles. Novel concepts are needed to facilitate these changes, which might be found by scouting patents of emerging and established companies. LÄS MER

7. 40. 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
