  • Honardoost, M.; Mota, David; Sepangi, H. R. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    We investigate the compatibility of the Symmetron with dark energy by introducing a non-minimal kinetic term associated with the Symmetron. In this new model, the effect of the friction term appearing in the equation of ...

    In recent years realistic 3D numerical models of the solar atmosphere have become available. The models attempt to recreate the solar atmosphere and mimic observations in the best way, in order to make it possible to couple ...
  • Oppegaard, Christine (Master thesis / Masteroppgave, 2007)
    Gravitational lensing has played an important role in cosmology since the discovery of the first gravitational lensing system in 1979 (Walsh et al.), where the quasar QSO 0957+561 can be seen in two images. Such multiple ...
  • Mota, David; Salzano, Vincenzo; Capozziello, S. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)
    We investigate whether there is any cosmological evidence for a scalar field with a mass and coupling to matter which change accordingly to the properties of the astrophysical system it “lives in,” without directly focusing ...
  • Axelsson, Magnus; Ihle, Håvard Tveit; Scodeller, Sandro; Hansen, Frode Kristian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    We test for foreground residuals in the foreground-cleaned Planck cosmic microwave background (CMB) maps outside and inside the U73 mask commonly used for cosmological analysis. The aim of this paper is to introduce a new ...

  • Llinares, Claudio (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The dynamics of globular clusters has been studied in great detail in the context of general relativity as well as with modifications of gravity that strongly depart from the standard paradigm such as Modified Newtonian ...
  • Jønvik, Sara Clausen (Master thesis / Masteroppgave, 2017)
    We perform an investigation of quadru- and octopolar asymmetry in the CMB data by expanding the on the study of alignment and angular clustering of the dipole components of the CMB power distribution across multipoles l = ...

    The coldest and densest structures of gas and dust in the Universe have unique spectral signatures across the (sub-)millimetre bands (υ ≈30 - 950 GHz). The current generation of single dish facilities has given a glimpse ...
  • Chung, Andrew S.; Dijkstra, Mark; Ciardi, Benedetta; Kakiichi, Koki; Naab, Thorsten (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Galactic outflows are critical to our understanding of galaxy formation and evolution. However, the details of the underlying feedback process remain unclear. We compare Ly α observations of the circumgalactic medium (CGM) ...
