Measuring dark energy with the shear triplet statistics


Sereno, M (2007). Measuring dark energy with the shear triplet statistics. Monthly Notices of the Royal Astronomical Society, 377(1):229-233.

Abstract

The shear triplet statistics is a geometric method to measure cosmological parameters with observations in the weak gravitational lensing regime towards massive haloes. Here, this proposal is considered to probe the dark energy equation of state and its time derivative in view of future wide-field galaxy surveys. A survey with a median redshift of ∼0.7 and a total area of ∼10 000 deg2 would be pretty effective in determining the dark matter cosmological density and in putting useful constraints on the dark energy properties
