  1. 1. Black-Hole Universe

    Författare :Irina Galstyan; Kjell Rosquist; Ingemar Bengtsson; Sören Holst; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Sammanfattning : In this thesis, we have constructed new analytical solutions for initial data of the Einstein equations. Such solutions are valuable for gaining a better understanding of problems involving strong gravitational and/or electromagnetic interactions in general relativity. LÄS MER

  7. 5. Probing the early Universe with B-mode polarization : The Spider instrument, optical modelling and non-Gaussianity

    Författare :Adriaan Judocus Duivenvoorden; Katherine Freese; Jón Emil Gudmundsson; Juan García-Bellido; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cosmic microwave background; early universe; polarimetry; telescopes; fysik; Physics;

    Sammanfattning : One of the main goals of modern observational cosmology is to constrain or detect a stochastic background of primordial gravitational waves. The existence of such a background is a generic prediction of the inflationary paradigm: the leading explanation for the universe's initial perturbations. LÄS MER
