Title: Lyman-alpha imaging of a known z=8.2 field

Abstract: Finding and studying sources in the era of reionization is the dominant driving force behind many projects in contemporary astrophysics. Our discovery of GRB090423 at z=8.2 offers a new window on the galaxy population only 600Myrs after the Big Bang. By good fortune, our redshift measurement places Lyman-alpha in a dark region of the spectrum between bright sky lines. We therefore propose a deep search for Lyman-alpha emission from the host and any neighbouring galaxies, making use of an existing NIRI narrow-band filter. These observations will give crucial new constraints on clustering, star-formation and emergent UV flux for galaxies at these early times, and they form a key part of our intensive multiwavelength study of the GRB090423 field.
