The state of the dark energy equation of state [PDF]

open access: yesPhysical Review D, 2003
By combining data from seven cosmic microwave background experiments (including the latest WMAP results) with the Hubble parameter measurement from the Hubble space telescope and luminosity measurements of type la supernovae, we demonstrate the bounds on the dark energy equation of state wQ to be - 1.45<wQ< -0.74 at the 95% confidence level ...
