Evolution of the sizes of the Lyman line_3: alpha clouds will be studied with ultraviolet spectra of a well separated pair line_4: of QSO images. line_5: In two "gravitational lensing" multiple QSOs, we shall ascertain line_6: whether the UV spectra of the images are identical, while detecting line_7: absorption lines (especially Lyman alpha) which might exhibit differences and line_8: hence give information on sizes of absorbing clouds. ! ! end of abstract general_form_proposers: lname: HARMS fname: RICHARD mi: J. inst: APPLIED RESEARCH CORPORATION country: USA ! lname: ALLEN fname: RICHARD mi: G. inst: UNIVERSITY OF ARIZONA country: USA ! lname: ANGEL fname: J.

Absorption lines such as C IV lambda1549 due to line_4: low and medium redshift galaxies and galaxy clusters near QSO sight line_5: lines will be in the UV. UV absorption lines are a better probe of gas line_6: for this sight lines than optical absorption lines, and the UV line_7: observations are required in order to understand the evolution of the line_8: sizes of these clouds. ! question: 4 section: 2 line_1: The collecting area of HST and the sensitivity of the FOS and GHRS line_2: make it possible to obtain spectra with the signal to noise needed to line_3: carry out these studies of QSOs at wavelengths below the atmospheric line_4: cutoff. ! question: 6 section: 1 line_1: Experience has shown that the FOS has siginficant wavelength line_2: errors due to the uncertainty in the setting of the filter/ line_3: grating wheel. In many cases this is not a problem, but for line_4: this program we require greater accuracy because we must line_5: accurately compare redshifts of lines detected in the two line_6: objects. ! question: 7 section: 1 line_1: Absorption lines in the spectra of the line_2: two gravitational lens images will be measured using the standard line_3: software. Monte-Carlo simulations of the absorption line coincidences line_4: along these two closely spaced lines of sight will be used to estimate line_5: the size of the Ly-alpha forest H I clouds. The association of line_6: absorption lines with galaxies and clusters of galaxies along the QSO line_7: line of sight will be established by obtaining accurate redshifts for line_8: the absorption system and the intervening object. ! question: 7 section: 2 line_1: These observations will be reduced using the standard spectroscopy and line_2: polarimetry reduction software available for FOS data. Calibration line_3: will be done using the results of SV observations. ! question: 8 section: 1 line_1: Optical polarimetry and photometry will be performed using the line_2: facilities of Steward Observatory. Optical spectroscopy and line_3: photometry will be performed using the facilities of Lick Observatory. line_4: We will try to make the optical observations simultaneous with the line_5: HST UV observations if possible. This imposes no requirements on HST line_6: scheduling except as noted in question 5. line_7: Coordinates need to be determined from WF/PC team images for line_8: target acquisition. This will be done shortly. line_10: There are a number of related FOS IDT GTO proposals in cycles 0, 1, line_11: and 2. These observations were originally written as portions line_12: of observations begun in those proposals. Thus the observations line_13: included here contain both the baseline and augmented portions. Some line_14: observations were moved from augmented to baseline proposals to line_15: balance this. ! question: 9 section: 1 line_1: Collaborators have received data from a number of GTO programs, SAT, line_2: and ERO programs. Related programs which have had observations are as line_3: follows: line_4: 1026 - ``UV Spectra of Low-Redshift-QSOs'', line_5: 1027 - ``UV Spectra of QSOs with z> 3.1'', line_6: 1029 - ``Spectropolarimetry of QSOs, Blazars, and AGN'', and line_7: 1033 - ``Search for Misdirected BL Lac Objects''. line_8: Low resolution observations of three high redshift QSOs have not line_9: revealed any with light at He II lambda 304. Observations of UM 675 line_10: have shown that any He I Gunn--Peterson effect is small, that He I line_11: absorption lines are not strong, that predictions of the ``Lyman line_12: valley'' may be correct, and that low redshift Ly-alpha is more line_13: prevalent than expected. Observations of low redshift QSOs (including line_14: 3C 273) have shown even more clearly that Ly-alpha absorption occurs line_15: in greater numbers than expected, as well as showing emission--line line_16: profile differences more clearly than from earlier data. line_17: Unexpectedly, Ly-alpha is narrower than H-alpha. ! question: 9 section: 2 line_1: ``HST Imaging of the Inner 3 Arcseconds of NGC 1068 in the Light of [O line_2: III] lambda5007'', I.N.Evans, H.C.Ford, A.L.Kinney, R.R.J.Antonucci, line_3: L.Armus, and S.Caganoff, {\it Ap.J.(Lett.)}, {\bf 369}, L27, 1991. line_4: ``Faint Object Camera Observations of a Globular Cluster Nova Field'', line_5: B.Margon, S.F.Anderson, R.A.Downes, R.C.Bohlin, and P.Jakobsen, {\it line_6: Ap.J.(Lett.)}, {\bf 369}, L71, 1991. line_7: ``Far--Ultraviolet Spectroscopy of the Quasar UM 675 with the Faint line_8: Object Spectrograph on the Hubble Space Telescope'', E.A.Beaver, line_9: E.M.Burbidge, R.D.Cohen, V.T.Junkkarinen, R.W.Lyons, E.I.Rosenblatt, line_10: G.F.Hartig, B.Margon, and A.F.Davidsen, {\it Ap.J.(Lett.)}, {\bf 377}, line_11: L1, 1991. line_12: ``The Ultraviolet Absorption Spectrum of 3C 273'', J.N.Bahcall, line_13: B.T.Jannuzi, D.P.Schneider, G.F.Hartig, R.Bohlin, and V.Junkkarinen, line_14: {\it Ap.J.(Lett.)}, {\bf 377}, L5, 1991. line_15: ``Faint Object Spectrograph Spectroscopy of Resolved Structure in the line_16: Nucleus of NGC 1068'', S.Caganoff, R.R.J.Antonucci, H.C.Ford, line_17: G.A.Kriss, G.Hartig, L.Armus, I.N.Evans, E.Rosenblatt, R.C.Bohlin, and line_18: A.L.Kinney, {\it Ap.J.(Lett.)}, {\bf 377}, L9, 1991. line_19: ``Faint Object Spectrograph Observations of the Low-Luminosity Seyfert line_20: Galaxy NGC 1566'', G.A.Kriss, G.F.Hartig, L.Armus, W.P.Blair, line_21: S.Caganoff, and L.Dressel, {\it Ap.J.(Lett.)}, {\bf 377}, L13, 1991. ! question: 10 section: 1 line_1: The majority of the resources required for this project other than the line_2: normal facilities of a university (librarys, offices, etc.) were line_3: supplied by NASA to the members of the FOS IDT for these projects. line_4: These include all the computing facilities required for the completion line_5: of data reduction and analysis. line_6: Optical and IR ground--based observing facilities and support are line_7: provided by the University of California and the University of line_8: Arizona. ! !end of general form text general_form_address: lname: BURBIDGE fname: E.
