Abstract

The First Light And Reionisation Epoch (FLARE), roughly the first billion years, is a critical period in the Universe’s history. The FLARE encompasses: the formation of the formation of the first stars; the transition from metal-free (population III ) to metal enriched (Population II) star formation; early enrichment of the ISM including the first production of dust; the formation of the first super-massive black holes and AGN ; and reionisation of the Universe’s neutral hydrogen. While Hubble and other telescopes have provided our first glimpse of the FLARE the upcoming Webb and Euclid telescopes will allow us to explore the early Universe in much more depth. In this talk I’ll introduce the FLARE before mentioning a couple of specific projects I work on. These include: a very-large hydrodynamical simulation of galaxy formation in the FLARE ; and the Cosmic Evolution Early Release Science (CEERS) Survey, a guaranteed time project on the Webb Telescope.
