We present results from a near-infrared narrow-band survey of emission-line galaxies at z = 2.23, using the Wide Field Camera on the United Kingdom Infrared Telescope. The H2S1 narrow-band filter ( �c = 2.121µm) we employ selects the Hemission line redshifted to z = 2.23, and is thus suitable for selecting 'typical' star forming g alaxies and active galactic nuclei at this epoch. The pilot study was undertaken in the well studied Cosmological Evolution Survey field (COSMOS) and is already the…
