Proposal Abstract
Using parallel opportunities with STIS which were not allocated by the TAC, we propose to obtain slitless spectroscopy with the G750L grism to search for emission line galaxies at intermediate to high redshift. Field galaxy surveys have shown that at high redshift most galaxies have strong emission lines, and are compact and blue. This suggests that star formation rates were higher than at present, and that AGN may have been more frequent. The low background and high resolution of HST separates these objects from the background. Short exposures with the 50CCD imaging mode will provide the wavelength zero-point calibration. In addition, the images will help to determine the connection between galaxy morphology and spectral type as a function of redshift. At low galactic latitude the same technique will be used to search for low mass stars and brown dwarfs. These data will be placed immediately into the Hubble Data Archive.
