The supernovae will serve as line_3: probes of the interstellar gas in the disk and halo, enabling us to search for line_4: Mg II and Mg I absorption lines arising from the host galaxy. The 6 km/s line_5: resolution of the echelle will allow us to resolve individual components which line_6: comprise the line. The accurate measurments of column densities & doppler line_7: parameters of each component and the large-scale multicomponent velocity line_8: structure of the lines will allow an unprecedented analysis of the chemical, line_9: ionization and kinematic conditions within the absorbing gas. For galaxies with line_10: low recession velocities, similar information may be obtained for local Milky line_11: Way absorption lines observed simultaneously. Because the galaxy which hosts line_12: the supernova will be obvious, the detected absorption can be compared with line_13: lines seen at higher redshifts in QSO spectra, providing an example of line_14: absorption from a KNOWN environment. line_16: A collation of all supernovae discovered over the last 10 years shows that line_17: roughly one supernova will be found during Cycle 2 with a magnitude brighter line_18: than our limit. We therefore request Target of Opportunity time to observe one line_19: supernova. Complementary observations of Ca II and Na I absorption will be made line_20: from ground-based telescopes. ! ! end of abstract general_form_proposers: lname: BLADES fname: CHRIS title: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE country: U.S.A. ! lname: BOWEN fname: DAVID mi: V. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: U.S.A. esa: Y ! lname: PETTINI fname: MAX inst: ROYAL GREENWICH OBSERVATORY country: U.K. esa: Y ! ! end of general_form_proposers block general_form_text: question: 2 section: 1 line_1: ! question: 3 section: 1 line_1: Discoveries of bright supernovae are announced via {\it IAU Telegrams}. We line_2: would activate our Target of Opportunity time based on the visual magnitude of line_3: the object ($<\:12.5$) and the redshift of the host galaxy, which must lie line_4: between $100-700$~\Ks\ or $>\: 850$~\Ks\ to ensure that there is no blending line_5: with local Milky Way gas. The flux from {\it IUE} data should be obtainable to line_6: ensure an adequate count rate with {\it HST}. We would observe the supernova line_7: for 5.2 hours at the redshift of Mg~II and 5.2 hours at Mg~I. line_9: In the unlikely event of finding a supernova with a magnitude brighter than line_10: 10.5, we would spend 7 hours using the 160M grating to search for C~IV, and line_11: divide the remaining 3.4 hours between Mg~II and Mg~I, since the opportunity to line_12: identify C~IV in a galactic halo would be too important to miss. ! question: 4 section: 1 line_1: Mg~II lines can only be observed for $z\:\apg\:0.2$ in the optical. These are line_2: therefore only accessible at lower redshifts with the {\it International line_3: Ultraviolet Explorer (IUE)}. {\it IUE} has a small aperture which permits line_4: detection of only strong ($1-2$~\AA ) lines in the brightest quasar spectra and line_5: is unsuitable for resolving the lines within a complex. line_7: {\it IUE} has only twice successfully identified UV absorption in the line_8: interstellar medium of an external galaxy. The spectrum of SN~1987a provided line_9: information on the strengths of many absorption lines (Blades~\etal\ 1988) from line_10: both the host galaxy (the LMC) and the Milky Way due to its line_11: brightness. Even with the exceptional signal-to-noise, however, the limited line_12: resolution of the telescope could not resolve the complex multi-component line_13: structure of the lines and only a simple analysis of the conditions within the line_14: gas was possible. The same problem beset the analysis of SN~1980k in NGC~6946 line_15: (Pettini~\etal\ 1982); in this case, the redshift of the galaxy was too low to line_16: distinguish absorption by the interstellar gas of NGC~6946 from local Milky Way line_17: gas. line_19: The {\it GHRS} plus {\it HST} is ideal for this study. The sensitivity of the line_20: instrument is high enough to detect weak Mg~II and Mg~I lines in bright line_21: supernovae, and, with the echelle, data can be obtained at a resolution which line_22: not only shows the large-scale velocity structure of the absorption-line line_23: profiles but should resolve all the components. This in turn permits a more ! question: 4 section: 2 line_1: accurate determination of column densities and doppler parameters, and leads to line_2: a more detailed analysis of the chemical, ionization and kinematics of the line_3: absorbing gas. For these two reasons, the {\it GHRS} is more suitable for line_4: studying the physics of galactic haloes than the {\it FOS}.\\ line_6: Our ground-based investigation into the interstellar medium of galaxies using line_7: supernovae as probes is still in progress. We have so far obtained high line_8: signal-to-noise, high-resolution observations of 8 supernovae in external line_9: galaxies, detecting absorption in Ca~II and/or Na~I in all but one of them. line_10: We would obtain data on Ca~II and Na~I in the supernova observed with {\it line_11: HST} to complement the UV data. ! question: 5 section: 1 line_1: The UV flux of supernovae fall off rapidly after the initial line_2: maximum. We thus wish to apply the minimum notification (two days) before the line_3: first observations are taken. ! question: 6 section: 1 line_1: We will use profile fitting routines to model the components within the line_2: absorption line and to establish the velocity of individual components to line_3: within a few tenths of a \Ks . We therefore require a wavelength accuracy line_4: better than the $\pm1$ diode (half a resolution element) normally line_5: available, and will need spectral calibration lamps taken before and after line_6: exposures, as suggested in the {\it GHRS} manual. ! question: 7 section: 1 line_1: All the data should be reducible using standard IRAF and STSDAS reduction line_2: packages. For absorption lines in which we resolve components, we line_3: have profile fitting routines available for subjective fits to the data, plus line_4: automatic routines which produce a best fit based on minimizing chi-squared. line_5: One of us (DVB) will work full time on the data reduction and analysis. ! question: 8 section: 1 line_1: As discussed in Section 1, over the last 10 years the frequency of supernovae line_2: brighter than 12.5 has been approximately one per year (Fig. 3). We therefore line_3: expect one possible candidate during Cycle~2. For supernovae with a magnitude line_4: $\geq\:12.0$ the frequency drops to approximately 1 every two years. Only one line_5: supernova (SN1987a) has had a magnitude brighter than 10 in the last 10 years. ! question: 9 section: 1 line_1: FOC: Blades is a member of the FOC IDT and is involved in several imaging line_2: programs, but these are not related to this program. line_4: 2553---``The Absorption Cross-Sections of Nearby Galaxies'' (Blades---PI). line_5: Related Program.
