(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 ...

The cosmic microwave background (CMB) radiation at 2.7 K is the leftover radiation from the Big Bang.
By studying this radiation we can extract much information about the universe we live in.
CMB experiments over the last ...

The theory of inflation gives certain predictions for the amount of primordial gravitational waves compared to the amount of density perturbations. These predictions are, in principle, verifiable through observation of the ...

Observations of how matter is distributed on different length scales in the universe are an important test of cosmological models. For example, such observations can give an upper limit for the mass of neutrinos: As the ...

The solar corona has a temperature of order 1 MK, which is almost 200 times the temperature of the underlying surface. This fact has puzzled solar physicists for more than six decades. As of today, most solar physicists ...

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 = ...
