Principal Investigator Institution Country Telephone E. margaret Burbidge UNIVERSITY OF CALIFORNIA, SA USA 619-534-4477 ------------------------------------------------------------------------------------ 7. Abstract Observe one of the brightest broad absorption line QSOs at low redshift to determine whether it has enough light for higher resolution observations. If so, these will be done with another proposal. The goal is to investigate the physical conditions in the BAL region through the study of the high ionization UV lines. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Margon UNIVERSITY OF WASHINGTON USA ------------------------------------------------------------------------------------ 3. Description of proposed observations. 1 QSO of z ~/= 2 will be observed with the FOS at low dispersion. After a binary search target acquision with the blue detector, the G160L grating and prism will be used for 950s and 500s, respectively with the large aperture to measure the UV flux. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. Absorption troughs of interest in the BALQSO Q1246-057 are shortward of the atmospheric cutoff. These cannot be observed in the optical for other BALQSOs. The collecting area of HST and the sensitivity of the FOS and GHRS make it possible to obtain spectra with the signal to noise needed to carry out these studies of QSOs at wavelengths below the atmospheric cutoff. ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. These observations will be reduced using the standard spectroscopy and polarimetry reduction software available for FOS data. Calibration will be done using the results of SV observations. ------------------------------------------------------------------------------------ 8. Additional comments or special requests. Optical polarimetry and photometry will be performed using the facilities of Steward Observatory. Optical spectroscopy and photometry will be performed using the facilities of Lick Observatory. We will try to make the optical observations simultaneous with the HST UV observations if possible. This imposes no requirements on HST scheduling except as noted in question 5. Coordinates for a few objects need to be determined to the accuracy required for target acquisition. These can easily be obtained from the guide star data base using the existing software. There are a number of related FOS IDT GTO proposals in cycles 0, 1, and 2. Most of these observations were originally written as portions of observations begun in those proposals. Thus the observations included here contain both the baseline and augmented portions. Some observations were moved from augmented to baseline proposals to balance this.

Collaborators have received data from a number of GTO programs, SAT, and ERO programs. Related programs which have had observations are as follows: 1026 - ``UV Spectra of Low-Redshift-QSOs'', 1027 - ``UV Spectra of QSOs with z> 3.1'', 1029 - ``Spectropolarimetry of QSOs, Blazars, and AGN'', and 1033 - ``Search for Misdirected BL Lac Objects''. Low resolution observations of three high redshift QSOs have not revealed any with light at He II lambda 304. Observations of UM 675 have shown that any He I Gunn--Peterson effect is small, that He I absorption lines are not strong, that predictions of the ``Lyman valley'' may be correct, and that low redshift Ly-alpha is more prevalent than expected. Observations of low redshift QSOs (including 3C 273) have shown even more clearly that Ly-alpha absorption occurs in greater numbers than expected, as well as showing emission-- line profile differences more clearly than from earlier data. Unexpectedly, Ly- alpha is narrower than H-alpha. ``HST Imaging of the Inner 3 Arcseconds of NGC 1068 in the Light of [O III] lambda5007'', I.N.Evans, H.C.Ford, A.L.Kinney, R.R.J.Antonucci, L.Armus, and S.Caganoff, {\it Ap.J.(Lett.)}, {\bf 369}, L27, 1991. ``Faint Object Camera Observations of a Globular Cluster Nova Field'', B.Margon, S.F.Anderson, R.A.Downes, R.C.Bohlin, and P.Jakobsen, {\it Ap.J.(Lett.)}, {\bf 369}, L71, 1991. ``Far--Ultraviolet Spectroscopy of the Quasar UM 675 with the Faint Object Spectrograph on the Hubble Space Telescope'', E.A.Beaver, E.M.Burbidge, R.D.Cohen, V.T.Junkkarinen, R.W.Lyons, E.I.Rosenblatt, G.F.Hartig, B.Margon, and A.F.Davidsen, {\it Ap.J.(Lett.)}, {\bf 377}, L1, 1991. ``The Ultraviolet Absorption Spectrum of 3C 273'', J.N.Bahcall, B.T.Jannuzi, D.P.Schneider, G.F.Hartig, R.Bohlin, and V.Junkkarinen, {\it Ap.J.(Lett.)}, {\bf 377}, L5, 1991. ``Faint Object Spectrograph Spectroscopy of Resolved Structure in the Nucleus of NGC 1068'', S.Caganoff, R.R.J.Antonucci, H.C.Ford, G.A.Kriss, G.Hartig, L.Armus, I.N.Evans, E.Rosenblatt, R.C.Bohlin, and A.L.Kinney, {\it Ap.J.(Lett.)}, {\bf 377}, L9, 1991. ``Faint Object Spectrograph Observations of the Low-Luminosity Seyfert Galaxy NGC 1566'', G.A.Kriss, G.F.Hartig, L.Armus, W.P.Blair, S.Caganoff, and L.Dressel, {\it Ap.J.(Lett.)}, {\bf 377}, L13, 1991. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). The majority of the resources required for this project other than the normal facilities of a university (librarys, offices, etc.) were supplied by NASA to the members of the FOS IDT for these projects. These include all the computing facilities required for the completion of data reduction and analysis. Optical and IR ground--based observing facilities and support are provided by the University of California and the University of Arizona. ------------------------------------------------------------------------------------ 11.
