  1. 6. Studies of cosmic rays with the anticoincidence system of the PAMELA satellite experiment

    Författare :Silvio Orsi; Mark Pearce; Martin Pohl; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; astrophysics; astroparticle physics; antimatter; organic scintillators; cosmic rays; trapped particles; Astroparticle physics; Astropartikelfysik;

    Sammanfattning : PAMELA is a satellite-borne experiment designed to study the charged component of the cosmic radiation of galactic, solar and trapped nature. The main scientific objective is the study of the antimatter component of cosmic rays over a wide range of energies (antiprotons: 80 MeV–190 GeV, positrons: 50 MeV–270 GeV). LÄS MER

  3. 7. Searching for an Ultra High-Energy Diffuse Flux of Extraterrestrial Neutrinos with IceCube 40

    Författare :Henrik Johansson; Christian Walck; Antoine Letessier-Selvon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutrinos; UHE; diffuse; IceCube; Astroparticle physics; Astropartikelfysik; fysik; Physics;

    Sammanfattning : Neutrino astronomy has the potential to greatly improve our understanding of the high-energy universe. An unresolved, diffuse, flux of neutrinos is sensitive to the properties of the population of cosmic accelerators in the universe. LÄS MER

  4. 8. The Anticoincidence System of the PAMELA Satellite Experiment : Design of the data acquisition system and performance studies

    Författare :Johan Lundquist; Mark Pearce; Tony Weidberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAMELA; satellites; astroparticle physics; electronics; anticoincidence system; trigger system; Astroparticle physics; Astropartikelfysik;

    Sammanfattning : PAMELA is a satellite-borne cosmic ray experiment. Its primary scientific objective is to study the antiproton and positron components of the cosmic radiation. This will be done with unprecedented statistics over a wide energy range (~10MeV to ~100GeV). LÄS MER

  7. 10. A search for solar dark matter with the IceCube neutrino telescope

    Författare :Gustav Wikström; Klas Hultqvist; John Carr; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; neutrinos; neutrino telescopes; IceCube; Astroparticle physics; Astropartikelfysik; fysik; Physics;

    Sammanfattning : Dark matter particles in the form of supersymmetric Weakly Interacting Massive Particles (WIMPs) could accumulate in the centre of the Sun because of gravitational trapping. Pair-wise annihilations of WIMPs could create standard model particles out of which neutrinos could reach the Earth. LÄS MER
