F-COSMOS: a near-infrared spectroscopic survey of
star-forming galaxies at z~1.6 in COSMOS with Subaru/FMOS

John Silverman (IPMU)

I will report on first results from an intensive Subaru program to carry out a large NIR spectroscopic survey of galaxies with 1.4 < z < 1.7 in the COSMOS field using the Fiber Multi-Object Spectrograph (FMOS). We are measuring dust-corrected star formation rates using the Halpha emission line detected in the H-band to determine whether a star-forming main sequence is evident at high-redshift. We also report on the mass-metallicity relation at high redshift, dust content of our sample, and a comparison between star formation rate indicators (UV, Halpha, FIR). The aim of our survey is to obtain a sufficient sampling in the central square degree of COSMOS to characterize the local environment and its impact on star formation.
