We have studied bounds on the neutrino mass using new data from the WMAP 3 year data, the Sloan Digital Sky Survey measurement of the baryon acoustic (BAO) peak, the Type Ia supernovae from SNLS, and the Lyman-α forest. We find that even in the most general models with a running spectral index where the number of neutrinos and the dark energy equation of state are allowed to vary, the 95% confidence limit (C.L.) bound on the sum of neutrino masses is eV (95% C.L.), a bound which we believe to…
