The supernova Hubble diagram for off-center observers in a spherically symmetric inhomogeneous universe
Havard Alnes, Morad Amarzguioui
We have previously shown that spherically symmetric, inhomogeneous universe models can explain both the supernova data and the location of the first peak in the CMB spectrum withou…
Resolution of an apparent inconsistency in the electromagnetic Casimir effect
H. Alnes, K. Olaussen, F. Ravndal +1
The vacuum expectation value of the electromagnetic energy-momentum tensor between two parallel plates in spacetime dimensions D > 4 is calculated in the axial gauge. While the pre…
Electromagnetic Casimir energy with extra dimensions
H. Alnes, K. Olaussen, F. Ravndal +1
We calculate the energy-momentum tensor due to electromagnetic vacuum fluctuations between two parallel hyperplanes in more than four dimensions, considering both metallic and MIT…
CMB anisotropies seen by an off-center observer in a spherically symmetric inhomogeneous universe
Havard Alnes, Morad Amarzguioui
The current authors have previously shown that inhomogeneous, but spherically symmetric universe models containing only matter can yield a very good fit to the SNIa data and the po…
An inhomogeneous alternative to dark energy?
Havard Alnes, Morad Amarzguioui, Oyvind Gron
Recently, there have been suggestions that the apparent accelerated expansion of the universe is not caused by repulsive gravitation due to dark energy, but is rather a result of i…
Black-body radiation in extra dimensions
H. Alnes, F. Ravndal, I. K. Wehus
The general form of the Stefan-Boltzmann law for the energy density of black-body radiation is generalized to a spacetime with extra dimensions using standard kinetic and thermodyn…
