  • Forfang, Peder (Master thesis / Masteroppgave, 2017)
    Following the discovery of the late-time acceleration, a multitude of extensions to General Relativity have been developed, seeking to shed light on this new phenomenon. Some of these models involve couplings to ordinary ...
  • Oppen, Henrik (Master thesis / Masteroppgave, 2014)
    Studier av vekselvirkningsmodeller for baryonsk materie, mørk materie og mørk energi. Hovedfokus på stabilitet for universmodeller, sammenligning med observasjonelle data og konsekvenser for strukturformasjoner.
  • Ihle, Håvard Tveit (Master thesis / Masteroppgave, 2016)
    If dark matter, after it has become non-relativistic, scatters elastically with a relativistic heat bath particle, then the resulting pressure leads to acoustic oscillations that suppress the growth of overdensities in the ...

    SDSS J2222+2745 is a galaxy cluster at z = 0.49, strongly lensing a quasar at z = 2.805 into six widely separated images. In recent Hubble Space Telescope imaging of the field, we identify additional multiply lensed galaxies ...
  • Hauge, Lars Christian (Master thesis / Masteroppgave, 2015)
    In 2013 a new metric called TARDIS was introduced. This metric was published by Tippet and Tsang, and described a time machine. This thesis uses numerical methods to explore properties of this new metric. We start by ...

  • Kianfar, S; Jafarzadeh, Shahin; Mirtorabi, MT; Riethmüller, T. L. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We present detailed characteristics of linear polarization features (LPFs) in the quiet-Sun photosphere from high-resolution observations obtained with SUNRISE/IMaX. We explore differently treated data with various noise ...
  • Thorsrud, Mikjel; Mota, David; Urban, Federico (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    Cosmological local observables are at best statistically determined by the fundamental theory describing inflation. When the scalar inflaton is coupled uniformly to a collection of subdominant massless gauge vectors, ...

  • Dijkstra, Mark; Gronke, Max Balthasar; Venkatesan, Aparna (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    The escape of ionizing Lyman continuum (LyC) photons requires the existence of low-NH I sightlines, which also promote escape of Lyα. We use a suite of 2500 Lyα Monte-Carlo radiative transfer simulations through models of ...
