Interpreting the astrophysics of reionisation within a Bayesian framework using 21CMMC  [slides]

Abstract

Observing the cosmic 21cm signal is set to revolutionise our understanding of the early Universe, opening a window onto the unseen first galaxies during the epoch of reionisation (EoR) and cosmic dawn. However, at present the astrophysics of reionisation are poorly constrained and understood. In order to quantify what we can learn from current and future experiments I developed 21CMMC, a Bayesian analysis tool which performs full 3D semi-numerical simulations on the fly. Using the recovered fractional precision on astrophysical parameters as a figure of merit, 21CMMC has wide ranging applicability to the EoR community. In this talk, I will introduce 21CMMC and discuss several of its applications.
