  1. 1. Was Einstein Wrong? : Theoretical and observational constraints on massive gravity

    Författare :Marcus Högås; Edvard Mörtsell; David Mota; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gravity; Massive gravity; Bimetric gravity; Cosmology; Gravitational collapse; Gravitational waves; Observational constraints; Theoretical Physics; teoretisk fysik;

    Sammanfattning : For more than a century, Einstein's theory of general relativity has described gravitational phenomena with astonishing precision. However, for the theory to fit observations we need to add two elusive substances: dark energy and dark matter. Together they add up to 95% of the energy budget of the Universe. LÄS MER

  2. 2. Delving in the Dark : Searching for Signatures of Non-Standard Physics in Cosmological and Astrophysical Observables

    Författare :Janina J. Renk; Joakim Edsjö; Pat Scott; Felix Kahlhöfer; David F. Mota; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cosmology; gravitation; Galileon; dark energy; dark matter; cosmic superstrings; neutrino mass; parameter inference; teoretisk fysik; Theoretical Physics;

    Sammanfattning : The dark sectors of our Universe, dark matter and dark energy, together constitute about 96 % of the total energy content of the Universe. To date, we only have observational evidence for their existence. LÄS MER
