Peering towards Cosmic Dawn (IAU S333) Proceedings of the International Astronomical Union Symposia and Colloquia Series

Several Epoch of Reionization (EoR) experiments, for example, LOFAR, MWA and PAPER, are currently under way and producing results. These very deep observations not only set constraints on when and where the first sources formed in the early Universe and began (re)ionizing the predominantly neutral all-pervasive intergalactic medium, but they also provide high-quality data for cutting edge auxiliary foreground science. Obviously studying the physical origin of the foreground emission, whether Galactic or extragalactic, is a very exciting field in its own right and is of fundamental importance for perfecting the foreground removal techniques in the cosmological experiments. These proceedings of IAU S333 address both topics through giving the clearest and widest possible view on the EoR; presenting the state-of-the-art foreground science; and discussing challenges of upcoming and planned radio facilities such as HERA and SKA.
