摘要
We investigate the correlation between the neutrino mass limit and dark energy with the time evolving equation of state. Parametrizing dark energy as w=w(0)+w(1)*z/(1+z), we make a global fit using Markov Chain Monte Carlo technique to determine w(0), w(1), neutrino mass as well as other cosmological parameters simultaneously. We pay particular attention to the correlation between neutrino mass Sigma m(nu) and w(1) using current cosmological observations as well as the future simulated data sets such as PLANCK, SNAP, and LAMOST.
