    Context. The solar coronal heating problem has been an open question in the science community since 1939. One of the proposed models for the transport and release of mechanical energy generated in the sub-photospheric ...

    We report the identification of extended Lyα nebulae at z ≃ 3.3 in the Hubble Ultra Deep Field (HUDF, ≃40 kpc × 80 kpc) and behind the Hubble Frontier Field galaxy cluster MACSJ0416 (≃40 kpc), spatially associated with ...

  • Hole, Ida Benedikte Amlie (Master thesis / Masteroppgave, 2012)
    The inverse-C shape of the bisector from the chromospheric Ca triplet spectral lines is a little understood phenomena. This spectral signature can give valuble information about the chromosphere, which is the least understood ...

  • Grindstad, Maren Klemetsen (Master thesis / Masteroppgave, 2010)
    Neutrino cosmology is a very interesting field of research, where properties of some of the smallest constituents of the universe are probed by the very largest structures of the universe; large scale structures of the ...

    We study the mean absorption spectrum of the Damped Lyα (DLA) population at z ~ 2.6 by stacking normalized, rest-frame-shifted spectra of ~27,000 DLA systems from the DR12 of the Baryon Oscillation Spectroscopic Survey ...
  • Børve, Steinar; Sato, Hiroatsu; Pecseli, Hans; Trulsen, Jan Karsten (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)
    Oscillations with periods on the order of 5–10 min have been observed by instrumented spacecrafts in the Earth's magnetosphere. These oscillations often follow sudden impacts related to coronal mass ejections. It is ...
  • Bø, Iselin M Thomassen (Master thesis / Masteroppgave, 2008)
    Systematic anomalies that seem to follow the first ionisation potential (FIP) of the minor, heavy elements at the sun, have been found when comparing the observed elemental abundances in the upper solar atmosphere with the ...
  • Pucci, Stefano (Master thesis / Masteroppgave, 2008)
    In-situ observations together with spectroscopic measurements show that the elemental abundance in the solar atmosphere varies from the photosphere to solar wind. An enrichment for low First Ionisation Potential elements ...

    In spite of their conjectured importance for the Epoch of Reionization, the properties of low-mass galaxies are currently still very much under debate. In this article, we study the stellar and gaseous properties of faint, ...
  • Garay, Carlos Peña; Verde, Licia; Jimenez, Raul (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    Recent constrains on the sum of neutrino masses inferred by analyzing cosmological data, show that detecting a non-zero neutrino mass is within reach of forthcoming cosmological surveys. Such a measurement will imply a ...
