"Marginal evidence for cosmological acceleration from Type Ia supernovae"

The paper calculates that the significance for cosmological
acceleration based on post-1990s SN Ia data is less than 3-sigma.

From a completely different point of view, my latest paper
(arXiv:1505.02917) also argues that uncertainties in the cosmological
parameters are larger than is generally assumed.
