(Master thesis / Masteroppgave, 2006)
Two galaxy clusters, Abell 1351 and Abell 1995, are examined using weak gravitational lensing
techniques. Mass maps are created, and the clusters' density and shear profiles are compared to
theoretical predictions.
Gravitational ...

The existence of dark matter is a well established fact both due to galaxy rotation curves and also due to the CMB temperature anisotropies and the matter power spectra. According to the $\Lambda$CDM model, the so called ...

In this thesis the correlation between star formation and dynamical state of a statistical well defined selection of galaxy clusters have
been studied. From simulations and theory it is expected strong
correlations between ...

Magnetic bright points (MBPs) are small-scale (generally kG) magnetic features, ubiqui- tous in the lower solar atmosphere, and are a manifestation of solar magnetism. They represent the cross-sections of thin flux tubes ...

En mulig forklaring på at universet gikk inn i en fase av akselerert ekspansjon for 5-6 milliarder år siden, er at energitettheten i universet inneholder et bidrag fra et dynamisk skalarfelt. Problemet med denne forklaringen ...

The universe is full of stuff we cannot see, neither directly or indirectly. We do not understand the nature of the mysterious dark matter and how it interacts with normal matter. Big Bang Nucleosynthesis (BBN) provides ...

Late time accelerated expansion of the universe is usually considered to be the result of dark energy, and the standard model of cosmology implements the cosmological constant as the drive of the acceleration of the universe. ...

Weak gravitational lensing provides a way of estimating the mass and mass distribution of galaxy clusters at large radii. The clusters act as lenses, so that light emitted by background sources, is bent and distorted by ...

Due to the accelerated expansion of the visible Universe, the Symmetron has been proposed as a modification of the standard Einstein field equations. I investigate the feasibility of the Symmetron in light of radial ...
