Abstract
We propose to use the GNIRS IFU to map the emission-line
structure of a sample of sub-mm selected galaxies from an unique catalog
of spectroscopically-identified SCUBA galaxies at z~2. The
proposed IFU observations will probe the dynamics and structural
information allowing us to test the claims that far-IR luminous
galaxies comprise merging systems which are likely to be the
progneitors of local massive ellipticals, or whether instead they
are simply high-luminosity episodes in the history of more
mundane galaxies.
Furthermore, by mapping the distribution of OIII, Hbeta and H-alpha emission
we will provide crucial diagnostics to the physical mechanism generating
their huge luminosities, testing whether AGN or starburst activity dominates
their power-source, as well as the spatially resolved, reddening corrected
star-formation rates.
