Sub-eV upper limits on neutrino masses from cosmology
Oystein Elgaroy, Ofer Lahav
Upper limits on neutrino masses from cosmology have been reported recently to reach the impressive sub-eV level, which is competitive with future terrestrial neutrino experiments.…
Cosmological constraints on f(R) gravity theories within the Palatini approach
M. Amarzguioui, O. Elgaroy, D. F. Mota +1
We investigate f(R) theories of gravity within the Palatini approach and show how one can determine the expansion history, H(a), for an arbitrary choice of f(R). As an example, we…
Neutrino Masses from Cosmological Probes
Oystein Elgaroy, Ofer Lahav
There is a renewed interest in constraining the sum of the masses of the three neutrino flavours by using cosmological measurements. Solar, atmospheric, and reactor neutrino experi…
The Integrated Sachs-Wolfe effect as a probe of non-standard cosmological evolution
T. Multamaki, O. Elgaroy
The Integrated Sachs-Wolfe effect is studied in non-standard cosmologies. By considering flat universes with a non-fluctuating dark energy component, it is shown how the quadrupole…
