  2. 6. WIMP searches in an Effective Field Theory Framework from XENON1T to XENONnT

    Author : Vasile Cristian Antochi; Conrad Jan; Alfredo Davide Ferella; Samuel Silverstein; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; WIMP; Dark Matter; EFT; Chiral EFT; Direct Detection; PMT testing; fysik; Physics;

    Abstract : Observations from cosmology and astronomy suggest that most of the matter in the Universe is comprised of dark matter. In this thesis the evidence for dark matter and the possible candidates are explored, focusing on the Weakly Interacting Massive Particles (WIMPs) hypothesis. READ MORE

  4. 7. Dark matter signal normalisation for dwarf spheroidal galaxies : A frequentist analysis of stellar kinematics for indirect Dark Matter searches

    Author : Andrea Chiappo; Jan Conrad; Piero Ullio; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dark matter; dwarf galaxies; kinematics and dynamics of galaxies; fysik; Physics;

    Abstract : Indirect detection strategies of Dark Matter (DM) entail searching for signals of DM annihilation or decay, typically in the form of excess positrons or high-energy photons above the astrophysical background, originating from (inferred) DM-rich environments. Due to their characteristics, dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are considered very promising targets for indirect particle DM identification. READ MORE

  5. 8. Prior-less derivation of the astrophysical factor of Dwarf Spheroidal galaxies

    Author : andrea chiappo; jan dr. conrad; garrelt mellema; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dwarf galaxies; dark matter; fysik; Physics;

    Abstract : Dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are considered ideal targets for particle Dark Matter (DM) identification. Indirect detection strategies entail examining dSphs in search for signals of annihilating or decaying DM, in the form of excess electrons or gamma- and X-ray photons above the astrophysical background.

  6. 9. Dark Matter searches targeting Dwarf Spheroidal Galaxies with the Fermi Large Area Telescope

    Author : Maja Garde Lindholm; Jan Conrad; Alexander L. Read; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dark matter; Fermi-LAT; dwarf spheroidal galaxies; fysik; Physics;

    Abstract : In this thesis I present our recent work on gamma-ray searches for dark matter with the Fermi Large Area Telescope (Fermi-LAT). We have targeted dwarf spheroidal galaxies since they are very dark matter dominated systems, and we have developed a novel joint likelihood method to combine the observations of a set of targets.

  7. 10. Model for End of Life Treatment of Polymer Composite Materials

    Author : Anna Hedlund-Åström; Jan-Gunnar Persson; Conrad Luttropp; Sigbritt Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer composites; material recycling; energy recovery; environmental effects; recommendations; waste treatment model; Environmental engineering; Miljöteknik;

    Abstract : Because of increasing environmental demands, especially on dealing with products end of life phase, product manufacturers and designers must consider the future disposal of their products. For conventional materials like steel and aluminium well-functioning recycling methods exists. READ MORE
