Cosmological implications of the KATRIN experiment
Jostein R. Kristiansen, Oystein Elgaroy
The upcoming Karlsruhe Tritium Neutrino (KATRIN) experiment will put unprecedented constraints on the absolute mass of the electron neutrino, $\mnue$. In this paper we investigate…
Bayesian analysis of Friedmannless cosmologies
Oystein Elgaroy, Tuomas Multamaki
Assuming only a homogeneous and isotropic universe and using both the 'Gold' Supernova Type Ia sample of Riess et al. and the results from the Supernova Legacy Survey, we calculate…
Upper limits on neutrino masses from the 2dFGRS and WMAP: the role of priors
Oystein Elgaroy, Ofer Lahav
Solar, atmospheric, and reactor neutrino experiments have confirmed neutrino oscillations, implying that neutrinos have non-zero mass, but without pinning down their absolute masse…
A new upper limit on the total neutrino mass from the 2dF Galaxy Redshift Survey
O. Elgaroy, O. Lahav, W. J. Percival +27
We constrain f_nu = Omega_nu / Omega_m, the fractional contribution of neutrinos to the total mass density in the Universe, by comparing the power spectrum of fluctuations derived…
Superfluid vortices in neutron stars
O. Elgaroy, F. V. De Blasio
A microscopic, quantum mechanical model for neutron vortices in the crust of a neutron star is presented. After a brief introduction to the Bogoliubov- de Gennes equations, which f…
