Exploring the high-redshift Universe
Thanks to deep near-IR imaging from the Hubble Space Telescope and VISTA we are now capable of exploring galaxy population well within the epoch of reionisation, with the first detections of galaxies at z>10. More recently, ALMA has also begun obtaining observations of these sources revealing the nature of the ISM in these nascent galaxies and throwing up challenges for galaxy formation modelling. In the near future this period of the Universe’s history will be further opened up by facilities such as the James Webb Space Telescope, the Square Kilometre Array, and the upcoming generation of Extremely Large Telescopes. Numerical simulations and detailed modelling of the reionization epoch are crucial for reliable interpretation of those detections, for deriving the numbers, clustering and properties of the reionization sources and understand the structure formation at high-z. This session will review the current status of both the theoretical and observational progress in our understanding of distant galaxies and their role in the evolution of the Universe.
