HiZELS, the High-z Emission Line Survey, is a successful panoramic narrow-band Campaign Survey using WFCAM on UKIRT to detect and study emission line galaxies over the history of the universe. HiZELS employs narrow-band filters in the J,H and K-bands, with the primary aim of delivering large identically-selected samples of H-alpha emitting galaxies at redshifts of 0.84, 1.47 and 2.23. I will describe the project, provide a summary of the project status, and detail the main scientific results obtained so far: determination of the H-alpha luminosity function and measurement of the evolution of the cosmic star-formation rate density across the peak epoch of star-formation activity in the universe, using a single star-formation indicator; determination of the morphologies, masses, environments and dust-content of the star-forming galaxies; study of how star-formation activity depends on a galaxy’s mass and environment at high redshift; a detailed investigation of the evolution of the clustering properties of star-forming galaxies.
