HiZELS, the High redshift(Z) Emission Line Survey, is using WFCAM's wide
field of view on UKIRT to search for (mostly) star-forming galaxies at z
up to 9 using three sets of custom narrow band filters in the J, H and K
bands in square degree areas of extragalactic sky.

I will present results from an almost 2 sq. deg area (UKIDSS UDS + COSMOS)
which have allowed us to i) compute the luminosity function of H-alpha
emitters at different redshift "slices" within the critical "era" of
star-formation in the Universe (z=0.84, z=1.48, z=2.23) and thus the star
formation rate density at those epochs, ii) calculate the clustering
signal of these SF galaxies (showing them to be highly clustered) and iii)
study the mass (showing significant evidence of downsizing at least at
z=0.84) and morphology dependences (with HST/SUBARU). I will also present
the 2 robust z=8.9 Ly-alpha emitter candidates which have been found with
our survey, along with future prospects for the Ultra-VISTA survey.
