Measurements of the global star formation history of the universe greatly benefit from the combination of independent star formation rate (SFR) indicators, and from the use of a robust SFR tracer over a large redshift range to calibrate other SFR indicators accesible at redshifts where the first one is not available. The Hα luminosity is a well-understood reference SFR tracer, widely used in low-redshift surveys, but it shifts to the observationally-difficult near-infrared (NIR) at moderate redshifts, where only small statistical galaxy samples have spectroscopic Hα measurements. We present preliminary results of Hα NIR spectroscopy of 16 galaxies with redshifts in the range 0.8< z <1.0 drawn from the DEEP2 Galaxy Redshift Survey. The spectra were taken using the multi-slit mode of LIRIS (Long-slit Intermediate Resolution Infrared Spectrograph), installed at the 4.2-m WHT. Twelve out of 16 spectra yield robust (>5 σ) Hα detections. We compare SFRs from Hα luminosities to those derived from DEEP2 rest-frame UV measurements, and discuss various sources of discrepancies. We selected galaxies for which we expected to detect Hα in the J-band, based on [OII] measurements in DEEP2 optical spectra, and with redshifts such that Hα will appear in regions of good atmospheric transmission. This study is part of a larger program to obtain accurate Hα luminosities of about 50 star-forming galaxies at z˜1 in the Extended Groth Strip; our scientific goals are the measurement of SFRs from Hα, and the comparison and calibration of Hα and other SFR tracers such as the UV continuum, the [O II] emission line, or the far-IR luminosity, at z˜1. The study will be complemented with galaxy stellar masses, reddening estimates, galaxy morphologies and metallicities.
