  1. 1. Indirect Searches for Dark Matter in the Milky Way with IceCube-DeepCore

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Martin Wolf; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark Matter Annihilation; WIMP; Milky Way; IceCube Neutrino Observatory; DeepCore; neutrino; particle physics; high-energy physics; Physics; fysik;

    Abstract : Many astronomical observations, including rotational curve measurements of stars and the analysis of the cosmic microwave background, suggest the existence of an invisible matter density content in the Universe, commonly called Dark Matter (DM). Possibly, DM could be of particle nature, where Weakly Interacting Massive Particles (WIMPs) could be a viable DM candidate. READ MORE

  2. 2. Dark Matter in the Milky Way

    University dissertation from Stockholm : Stockholm University

    Author : Axel Widmark; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dark matter; Theoretical Physics; teoretisk fysik;

    Abstract : Den här licenciatuppsatsen bygger på två vetenskapliga artiklar, varav den första är skriven som ensamförfattare och den andra är skriven tillsammans med Dr. Giacomo Monari. De är båda på temat mörk materia i Vintergatan.Den första artikeln handlar om mörk materia som fångas i solen. READ MORE

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

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Samuel Flis; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; IceCube; neutrino; dark matter; halo; Milky Way; Physics; fysik;

    Abstract : 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. READ MORE

  4. 4. Chemical Abundance Analysis of Population II Stars The Summary Includes a Background in General Astronomy

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karin Jonsell; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomy; Galactic evolution; Halo; Milky Way; Oxygen; r-element; s-element; Stellar abundances; Astronomi; NATURAL SCIENCES Physics Astronomy and astrophysics; NATURVETENSKAP Fysik Astronomi och astrofysik;

    Abstract : We are made of stardust in the sense that most atomic nuclei around us have been formed by stars. Stars synthesise new elements and expel them to the interstellar medium, from which later new generations of stars are born. We can map this chemical evolution by analysing the atmospheric contents of old Galactic halo stars. READ MORE

  5. 5. Galactic Structure Revealed by Space Astrometry

    University dissertation from Lund Observatory, Lund University

    Author : Johan Holmberg; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomi; cosmic chemistry; Galactic structure; Milky Way Galaxy; Galactic kinematics and dynamics; Galactic chemical evolution; moving groups; solar neighbourhood; dark matter; astrometry; Hipparcos; space research; Astronomy; rymdvetenskap; kosmisk kemi; Space technology; Rymdteknik; Fysicumarkivet A:2001:Holmberg;

    Abstract : This work demonstrates how the structure of our Galaxy, the Milky Way, can be unveiled with the use of space astrometry. It consists of two parts, of which the first is a brief introduction to the fields of Galactic structure, covering the Galaxy's stellar constituents, how the Galaxy was formed and how it has evolved over time, both chemically and kinematically.
