Prospects for Constraining Neutrino Mass Using Planck and Lyman-Alpha Forest Data
Steven Gratton, Antony Lewis, George Efstathiou
In this paper we investigate how well Planck and Lyman-Alpha forest data will be able to constrain the sum of the neutrino masses, and thus, in conjunction with flavour oscillation…
Can we ever distinguish between quintessence and a cosmological constant?
Sirichai Chongchitnan, George Efstathiou
Many ambitious experiments have been proposed to constrain dark energy and detect its evolution. At present, observational constraints are consistent with a cosmological constant a…
Report by the ESA-ESO Working Group on Fundamental Cosmology
John A. Peacock, Peter Schneider, George Efstathiou +4
ESO and ESA agreed to establish a number of Working Groups to explore possible synergies between these two major European astronomical institutions. This Working Group's mandate wa…
