Cosmic Bayes: Datasets and priors in the hunt for dark energy

Michela Massimi discusses Bayesian methods in contemporary observational cosmology. She argues that they enter into three main tasks: (I) cross-checking datasets for consistency; (II) fixing constraints on cosmological parameters; and (III) model selection. This article explores some epistemic limits of using Bayesian methods. The first limit concerns the degree of informativeness of the Bayesian priors […]

In search of Dark Energy

Royal Astronomical Society, Burlington House, Piccadilly, London, 9 November 2018 We present some of our research on the use of Bayesian inferences in cosmology, and in particular in DES Year 1 results, at this event organised by the Dark Energy Survey Collaboration.  The group will also explore the latest reports on Supernova Ia, galaxy clusters, weak […]
