Current status in determining the EoS of dark
energy

WMAP7 E. Komatsu et al. e-Print
arXiv1001.4538
SNLS3, e-Print arXiv1104.1444 
Results 1) Current data has
constrained a lot of the theoretical
models 2) Cosmological constant is
consistent with the data 3)dynamical
models are not ruled out quintom
scenario mildly favored
