We present strong bounds on the sum of three active neutrino masses using selected cosmological datasets and priors in various cosmological models. We use combinations of the following baseline datasets: Cosmic Microwave Background (CMB) temperature data from Planck 2015, Baryon Acoustic Oscillations measurements from SDSS-III BOSS DR12, the newly released Type Ia supernovae (SNe Ia) dataset from Pantheon Sample, and a prior on the optical depth to re-ionization from 2016 Planck Intermediate results. We constrain cosmological parameters with these datasets with Bayesian analysis.
