  1. 6. Neutrino interactions and axion emission impact on core-collapse supernova simulations

    Författare :Aurore Betranhandy; Evan O'Connor; Jeremiah Murphy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Core-Collapse Supernovae; simulations; CCSN; PNS; neutrino; axion; Astronomy; astronomi;

    Sammanfattning : Core-Collapse Supernovae (CCSNe) are important phenomena in the scope of nucleosynthesis and, as the final stage of massive stars' life, they are key processes in the understanding of stellar evolution. They also are the birthplace of neutron stars and black holes, therefore they play a major role in the modelling and understanding of compact object mergers. LÄS MER

  3. 7. Weigh them all! : Cosmological searches for the neutrino mass scale and mass ordering

    Författare :Sunny Vagnozzi; Katherine Freese; Lars Bergström; Alessandra Silvestri; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neutrinos; neutrino mass; neutrino mass ordering; cosmology; cosmic microwave background; large-scale structure; galaxy surveys; dark energy; cosmic inflation; data analysis; teoretisk fysik; Theoretical Physics;

    Sammanfattning : The elusive neutrinos are among the most intriguing constituents of the particle zoo. The observation of neutrino flavour oscillations, indicating that neutrinos are massive, provides the only direct evidence for physics beyond the Standard Model. LÄS MER

  4. 8. Extending the observational reach of core-collapse supernovae for IceCube using high-energy neutrinos

    Författare :Nora Valtonen-Mattila; Erin O'Sullivan; Timothy Linden; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neutrino physics; Neutrino astrophysics; Supernovae; Core-collapse supernovae; Particle astrophysics; Fysik; Physics;

    Sammanfattning : Neutrino telescopes such as IceCube monitor for low-energy neutrinos O(10 MeV) produced in nuclear processes during core-collapse in supernovae. The detection horizon to the neutrino burst is 50 kpc, the distance to the Magellanic Clouds. LÄS MER

  5. 9. Searching for dark matter in the Galactic Halo with IceCube using high energy cascades

    Författare :Samuel Flis; Klas Hultqvist; Chad Finley; Emmanuel Moulin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IceCube; neutrino; dark matter; halo; Milky Way; fysik; Physics;

    Sammanfattning : The presence of dark matter is inferred at scales ranging from rotations of galaxies to imprints in the CMB – the Big Bang after-glow. The nature of dark matter is, however, still unknown as no detection other than the gravitational one has been made. LÄS MER

  7. 10. Exploring the potentials of next-generation, wavelength-shifting, optical sensors for IceCube

    Författare :Jakob Beise; Erin O'Sullivan; Christian Ohm; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neutrino Physics; Astroparticle Physics; Supernovae; Wavelength Shifters; IceCube;

    Sammanfattning : The IceCube Neutrino Observatory has sensitivity to MeV electron antineutrinos from core-collapse supernovae through an excess of the detection rate over the background. Wavelength-shifting sensors have the potential to greatly increase photon collection making it a promising candidate for improving the measurement of the supernova neutrino light curve in IceCube-Gen2.
