The DEEP2 Redshift Survey is the first project to study a large set of galaxies in the distant universe with spatial sampling and spectral resolution comparable to that achieved locally. By measuring the rest-frame wavelength separation of the [OIII] 4959/5007 Å doublet in DEEP2 spectra, we are able to test whether the fine structure constant α had the same value at z ˜ 0.73 as today. This test is made possible by the high resolution, precise calibration, and stability of the DEIMOS spectrograph. [OIII] measurements provide a less precise, but more robust, test of α variation than other commonly used techniques. DEEP2 is observing in four widely separated fields with the same instrument and methods; this allows a test for spatial variation in α in addition to temporal variation. If high spectral resolution is used, future surveys for baryonic acoustic oscillations could greatly expand sample sizes, yielding strong constraints.
