High resolution spectra of a sample of quasars will line_10: be obtained with the FOS; the spectra will have a rest frame equivalent line_11: width detection limit for unresolved absorption lines of 0.3 A. The survey line_12: data base will address fundamental questions, for example: What is the line_13: strength and origin of the UV background radiation\? How do gaseous line_14: galactic disks and halos evolve with redshift\? What processes govern the line_15: ionization of absorbing gas\?

The quasars will in general line_3: be observed at high resolution ($1300$) through the 0.25 by 2.0 arcsecond line_4: slit. For these observations the desired signal to noise ratio is 30 (per line_5: diode). The FOS red side with the G190H and G270H gratings will be used to line_6: cover the wavelength range 1600 to 3300 angstroms. The FOS blue side and line_7: G130H grating will be used to cover the range from 1100 to 1600 angstroms. line_8: Since the G130H observations require a great deal of time, for some objects line_9: low resolution G160L exposures through the 1.0 arcsecond apt. are used instead. line_10: These are designed to find targets suitable for future cycle G130H observations line_11: and do not require signal to noise of 30. For eash object a single Binary line_12: acquisition is used followed by peak up acquisitions into the slit. ! question: 4 section: 1 line_1: HST observations are required to observe the strong resonant line_2: absorption lines and the various emission lines of the most abundant line_3: elements, which are in the ultraviolet (inaccessible to terrestrial line_4: observations) for the small and moderate redshifts investigated in line_5: this project. Ground-based observations partially determine the line_6: character of the absorbing systems and emission line regions at larger line_7: redshifts, but spectra must be obtained in the ultraviolet to line_8: establish the cosmological evolution of the known types of absorbing line_9: systems and emission line regions, to permit optical identifications, line_10: to search for gas in known voids and clusters of galaxies, to test line_11: for large scale structure in absorbing systems, and to make possible line_12: follow-up high resolution studies of the physical conditions and of line_13: the chemical (and isotopic) abundances. IUE observations do not have line_14: sufficiently high signal-to-noise ratios for our sample of objects to line_15: permit answering the scientific questions listed in the section on line_16: scientific justification. Quasar absorption and emission lines have line_17: been studied extensively from the ground (see the review articles line_18: listed in the scientific justification), but of course only in the line_19: accessible optical region. ! question: 5 section: 1 line_1: No Realtime data needed ! question: 6 section: 1 line_1: We would like all observations of a given object to be obtained within line_2: a ten day interval. Since quasars are known to vary in brightness, the line_3: data for all wavelengths must be taken nearly simultaneously in order line_4: to determine the spectral energy distribution. Our observations of a line_5: given object are currently linked with NO GAP inorder to be more line_6: efficient in the use of spacecraft time (only one acquisition needed). ! question: 7 section: 1 line_1: The answer to this question is too long for the RPSS format; please line_2: see the paper submission for phase 1. ! question: 8 section: 1 line_1: See paper submission for phase 1. ! question: 9 section: 1 line_1: See paper submission for phase 1. ! question: 10 section: 1 line_1: See paper submission for phase 1. ! !end of general form text general_form_address: lname: BAHCALL fname: JOHN mi: N. category: PI inst: INSTITUTE FOR ADVANCED STUDY addr_1: OLDEN LANE, BUILDING E city: PRINCETON, N.J. state: NJ zip: 08540 country: U.S.A. phone: 609-734-8058 telex: 229 734 IAS UR ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: OJ287 descr_1: E,316,321 pos_1: PLATE-ID=0204 , pos_2: RA = 08H 54M 48.9S +/- 0.1S , pos_3: DEC = +20D 06' 30.0" +/- 1.0" equinox: 2000 rv_or_z: Z=0.306 fluxnum_1: 1 fluxval_1: V = 15.50 +/- 0.1 ! targnum: 2 name_1: PG1718+481 descr_1: E,313,321 pos_1: PLATE-ID=02D4 , pos_2: RA = 17H 19M 38.3S +/- 0.1S , pos_3: DEC = +48D 04' 12.2" +/- 1.0" equinox: 2000 rv_or_z: Z=1.084 fluxnum_1: 1 fluxval_1: V = 14.55 +/- 0.1 ! ! end of fixed targets !
