The stellar and gas-phase metallicities of star-forming galaxies at z=3.5
F. Cullen, A. E. Shapley, R. J. McLure et al.
In this talk I will present the results of an analysis of the rest-frame ultraviolet and optical spectra of 33 star-forming galaxies at 3.0 z 3. We find that the typical O/Fe ratios are approximately 2.5 times the solar value, demonstrating a clear alpha-enhancement signature as expected for young galaxies at early cosmic epochs. Moreover, within the stellar mass range of our sample, we find that the observed O/Fe-enhancement shows no strong stellar mass dependence. Finally, I will describe how the O/Fe-enhancement observed in high redshift systems might be related to O/Fe values measured for various stellar populations within the Milky Way.
