(Master thesis / Masteroppgave, 2010)
The solar chromosphere is a region where the thermodynamics are out of equilibrium, and realistic values of temperature and electron densities here are difficult to obtain. Hydrogen, being the most abundant element in solar ...
(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 ...
(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 ...

Inflation is a much discussed topic within the field of cosmology; it represents a time in the history of the Universe where a very rapid, exponential expansion was taking place. This expansion is needed in order for the ...

The Q/U-Imaging ExperimenT (QUIET) is a ground-based coherent polarimeter experiment, primarily targeting the detection of low-l B-mode polarization in the CMB. Such modes are a signature of primordial tensor perturbations, ...

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 ...
(Master thesis / Masteroppgave, 2008)
The solar chromosphere has previously been thought to be a homogenic layer of the solar atmosphere, but better observations have made it evident that the chromosphere is a highly dynamic area.
Spicules are structures ...
(Master thesis / Masteroppgave, 2010)
The statistical analysis of the Cosmic Microwave Background radiation to make estimates of the Power Spectrum is a comutationally heavy operation, involving large covariance matrices.
In this thesis I explore the possibility ...

(Master thesis / Masteroppgave, 2011)
The standard model of cosmology has proven to be a great success. Through measurements of the Cosmic Microwave Background radiation, cosmologists have been able to constrain parameters such as the age and geometry of the ...
