Star-forming galaxies can be identified by their excesses of emission in narrowband filters over the expected continuum emission derived from their broadband fluxes. We present a selection of redshift z=0.48 Hα, z=0.95 [0III] and z=1.61 [OII] emitting galaxies in the Subaru/XMM-Newton Deep Survey (SXDS) Center and South fields. These are selected by an excess emission in the NB973 filter over z-band. These three classes of objects are separated using broadband color-selection techniques and spectroscopic follow-up. Measurements of the strength of these emission lines are used to derive star-formation rates (SFRs) for galaxies at these redshifts, which in turn can help constrain the cosmic star-formation history.
