Title: Star Formation, Metal Enrichment and the Ionizing
Background at High-Redshift with Gemini and Subaru

Author: Dr Andrew Bunker, University of Oxford, UK

I will present our work on the star formation rate and history of
metal enrichment at redshifts beyond 1 using multi-object near-IR
spectroscopy with MOIRCS on Subaru. I will discuss the future
potential of FMOS and WFMOS to greatly expand this study. I will also
present results from a Gemini project to search for the ionizing
background at redshifts around 3 using extremely deep (100hour) GMOS
spectroscopy.
