Query: Predictions and Strategies for Integral-Field Spectroscopy of
  High-Redshift Galaxies   We investigate the ability of infrared integral-field spectrographs to map
the velocity fields of high redshift galaxies, presenting a formalism which may
be applied to any telescope and imaging spectrograph system. We discuss the
5-sigma limiting line fluxes which current integral-field spectrographs will
reach, and extend this discussion to consider future large aperture telescopes
with cryogenically cooled adaptive reimaging optics. In particular, we simulate
observations of spectral line emission from star-forming regions at redshifts z
= 0.5 to 2.5 using a variety of spatial sampling scales and give predictions
for the signal-to-noise ratio expected as a function of redshift. Using values
characteristic of the W.M. Keck II telescope and the new OH-Suppressing
InfraRed Imaging Spectrograph (OSIRIS) we calculate integral-field
signal-to-noise ratio maps for a sample of U_nGR color-selected star-forming
galaxies at redshift z ~ 2 - 2.6 and demonstrate that OSIRIS will be able to
reconstruct the two-dimensional projected velocity fields of these galaxies on
scales of 100 mas (~ 1 kpc at redshift z ~ 2). With signal-to-noise ratios per
spatial sample up to ~ 20, OSIRIS will in some cases be able to distinguish
between merger activity and ordered disk rotation. Structures on scales smaller
than 1 kpc may be detected by OSIRIS for particularly bright sources, and will
be easy targets for future 30m class telescopes.
