5. Abstract

The installation of STIS on HST has allowed two-dimensional optical and ultraviolet
slitless spectroscopy of faint objects from space for the first time. The STIS
Parallel Survey (SPS) routinely obtains broad band images and slitless spectra of
random fields in parallel with HST observations using other instruments. The SPS is
designed to study a wide variety of astrophysical phenomena, including the rate of
star formation in galaxies and detection of emission-line galaxies at intermediate
to high redshift. We have presented the first results of the SPS in Gardner et al
(1998), which demonstrated the capability of STIS slitless spectroscopy to detect
and identify emission-line galaxies. The redshift range of 0.0<z<1.6 is of
particular cosmological interest, as it approaches the peak of star formation and an
epoch of significant galaxy and cluster evolution. The SPS provides a unique view
into this important epoch through detection of emission line objects at 0.0<z<1.6,
where HAlpha, O III and/or O II can be detected. We propose to reduce and co-add the
direct and spectral images of the SPS and make them and a catalog of detected
objects available to the astronomical community through the World Wide Web. We
propose to identify the emission line galaxies, and use their numbers, redshifts and
magnitudes to determine the star formation rate of the universe at this important
epoch.
