Abstract: In these proceedings we report on HiZELS, the High-z Emission Line Survey,our successful panoramic narrow-band Campaign Survey using WFCAM on UKIRT todetect and study emission line galaxies at z~1-9. HiZELS employs the H2S1narrow-band filter together with custom-made narrow-band filters in the J andH-bands, with the primary aim of delivering large, identically-selected samplesof H-alpha emitting galaxies at redshifts of 0.84, 1.47 and 2.23. Comparisonsbetween the luminosity function, the host galaxy properties, the clustering,and the variation with environment of these H-alpha-selected samples areyielding unique constraints on the nature and evolution of star-forminggalaxies, across the peak epoch of star-formation activity in the Universe. Weprovide a summary of the project status, and detail the main scientific resultsobtained so far: the measurement of the evolution of the cosmic star-formationrate density out to z > 2 using a single star-formation indicator,determination of the morphologies, environments and dust-content of thestar-forming galaxies, and a detailed investigation of the evolution of theirclustering properties. We also summarise the on-going work and future goals ofthe project.
