Abstract
Using very deep near-infrared imaging we
have recently uncovered a substantial population of galaxies
at $z>2$ with red rest-frame
optical colors, complementary to the
well known UV-bright Lyman break galaxies.
Initial results from near-IR spectroscopy
suggest that these red galaxies are more massive,
more metal rich, and have higher ages than typical
Lyman break galaxies. However, the interpretation is
hampered by small number statistics and non-uniform selection
criteria. In the context of
the GNIRS Key Science Opportunity
we propose a public near-infrared spectroscopic survey of $K$-selected
galaxies at $2.1<z<2.7$, to provide a large and uniform dataset for the study
of massive galaxies in the early Universe.
GNIRS is a factor 4--6
times more efficient for this type of survey
than currently available spectrographs on other
large telescopes. This high efficiency enables us to substantially
increase the sample of $K$-selected high redshift galaxies with
high quality spectra.
We aim to measure
rest-frame optical continuum breaks and line emission
for $\sim 30$ $K$-selected galaxies at
$z\sim 2.5$. The goals are to measure star
formation rates, ages, dust content, linewidths,
and metallicities of these galaxies,
and to investigate correlations between these properties.
