Just time for a very quick post today to pass on thhe news that most of the 2015 crop of papers from the Planck mission have now been released and are available to download here. You can also find some related data products here.

I haven’t had time to look at these in any detail myself, but my attention was drawn (in the light of the recently-released combined analysis of Planck and Bicpe2/Keck data) to the constraints on inflationary cosmological models shown in this figure:

It seems that the once-popular (because it is simple) m^2 \phi^2 model of inflation is excluded at greater than 99% confidence…
