Description
Cosmic reionisation is one of the last major milestones in the global evolution of the Universe: by z~6, the hydrogen in the intergalactic medium becomes fully ionised by the radiation produced predominantly by massive stars in star-forming galaxies. Because of the increasing opacity of the IGM, completing the census of these ionising sources is still a major challenge on both the observational and theoretical sides.
In the past few years, low-z star-forming galaxies have been used to study how ionising photons are produced and how they escape in the IGM. In this talk, I will present some results from the largest of these surveys to date, the Low-Redshift Lyman Continuum Survey. I will then show how results obtained from these low-z studies can be applied to the Epoch of Reionisation by making use of semi-analytical tools.
