Presentation of (a subset of) the group

• What we care about:• The furthest (earliest) visible objects in the

Universe, at z>7

• Even further: the first objects and reionization, at z≃12

• Further still: current and future CMBexperiments

• Precision cosmology— high-tech (Bayesian) statistical analyses

• The nature of dark matter and dark energy

• Characterising & understanding(exo-)planets, moons, stars

• All emphasising principled statistical techniques to get optimal scientific results from data
