  We present preliminary results of H_alpha near-infrared spectroscopy of six
galaxies with redshifts z ~ 1 drawn from the DEEP2 Galaxy Redshift Survey. The
spectra have been taken with the multi-slit mode of LIRIS (Long-slit
Intermediate Resolution Infrared Spectrograph) installed at the 4.2-m William
Herschel Telescope. This is a pilot study for a larger program to obtain
H_alpha luminosities of about 50 star-forming galaxies at z ~ 1, with the aim
of deriving the corresponding star formation rates (SFRs) from H_alpha as well
as studying the relationship with other SFR indicators. The new galaxy sample
will be selected from the Extended Groth Strip Survey, where galaxies will also
have measures of stellar masses, reddening, far-IR data, and galaxy
morphologies.
