Abstract We propose an ambitious program designed to: (1) establish if high ionization, metal-rich halos/coronae were in place as early as z~1, which would imply that extended, early-epoch, galactic halos result from reprocessed galactic gas and that the kinematics are mechanically driven; (2) obtain the first comparison of the relative kinematics of low and high ionization species in z~1 galaxies, covering a wide range of N(HI) environments and MgII kinematic spreads up to ~400 km/s; (3) discriminate between single-phase and multi-phase ionization, and therefore spatial, absorbing structures (eg. MgII clouds embedded in diffuse high ionization halos); and (4) place constraints on the gas-phase metallicites in early-epoch galaxies. We propose to obtain STIS R=30, 000 (Delta v = 10 km/s) spectra of five bright quasars, for which the FOS/HST data are fully analyzed. Our observational goal is to resolve the absorption profiles of several low, intermediate, and high ionization species, including OVI, OI, NV, NIII, CIV, CIII, CII, SiIV, SiIII, and SiII, in 18 MgII absorption systems covering 0.5<=z<=1.3. We incorporate our high signal-to-noise HIRES/Keck (Delta v=6.6 km/s) profiles of MgII, MgI, and FeII of the low ionization absorbing gas, and our database of the absorbing galaxy luminosities, colors, and impact parameters. ------------------------------------------------------------------------------------ 8672( 4) - 05/16/03 17:38 - [ 2] Observations Description ------------------------ The proposed absorbers were selected from the HIRES/Keck sample of MgII systems obtained for the PI's doctoral thesis for which FOS/HST data were also available. The FOS data, which are fully reduced, calibrated, and analyzed system-by-system, have provided both the QSO flux values and a plethora of information on low, intermediate, and high ionization species associated with the Mg II absorbers. To determine which quasars to observe, we computed an observing efficiency: the number of STIS/HST orbits per MgII absorber required to obtain a S/N>=8 for CIV in all systems in a given QSO. The number of orbits was computed using the on-line STIS signal-to-noise simulator, accounting for the observing duty cycle of an HST orbit, assuming no special calibration requirements. From the simulated S/N spectra, after resampling for the STIS pixelization and accounting for the STIS resolution, we find that we will decrease the equivalent width detection limit by a factor of three to four over the current FOS limits. For transitions on the flat part of the curve of growth, this can result in a several dex decrease in the upper limits of the column densities (yielding constraining upper limits for the analysis).
