(Master thesis / Hovedoppgave, 2007)
The goals of this thesis are to provide a general introduction to CMB fundamentals, give an overview of non-Gaussianity analysis, and to compare the sensitivities of a selection of tests (Minkowski functionals, skeleton ...

(Master thesis / Hovedoppgave, 2005)
During inflation, the potential of the inflaton scalar field $\phi$,
drives the exponential expansion of the Universe. The nature of the
inflaton potential is presently unknown, but one hopes to learn more
from observations ...

The thesis examines the relation between
the magnetic field as measured by MDI and
the continuum intensity at four different
wavelengths (1319, 1199, 1037 and 910Å) as
measured by SUMER. A method for copointing
the instruments ...

Through the two-point correlation function the effects of limited sky
coverage and discretisation of data on satellite observations of the
cosmic microwave background (CMB) is examined. Analytical expressions
for the ...

Five years (1992-1997, ~2650 images) of optical observations of the
gravitational lens system QSO 0957+561 were analyzed using a new
photometry package developed by Jan Teuber and me. My supervisor was
Prof. Rolf Stabell, ...

It is believed that the Broad Emission Line Region of Quasars consists of discrete clouds. Due to the suspected small size of a cloud, the radiation from clouds may be strongly amplified by gravitational microlensing.
It ...
