Our recent paper on what cosmological datasets have to say about neutrinos has been accepted for publication in Physical Review Letters, and selected as an Editor’s Suggestion! A copy of the paper is publicly available on the arXiv. The work is discussed in comprehensive blog posts at phys.org (here and here), on the UCL Science Blog, and in a recent guest post on our group website Early Universe @UCL. Below is a pretty picture that we considered for the press release but didn’t use in the end. It shows typical observations of some data sets we’ve used in this work: galaxy clustering, CMB, X-ray and SZ clusters.
