Abstract We propose to complete our program to produce THE definitive sample of radio loud quasar spectra, each measured from rest wavelength below Ly-alpha to beyond H-alpha. This is the ONLY large complete HST sample being used to investigate the intrinsic properties of quasars. The FOS data are being supplemented with quasi-simultaneous optical and infrared spectroscopy from McDonald Observatory, KPNO, UKIRT, and CTIO. The ~ 50 objects are selected to cover a wide range in radio-core dominance - a measure of inclination of the central engine's axis; we constrain the range in extended radio luminosity, which is inclination INDEPENDENT, in order to test the dependence of spectro- scopic parameters on inclination alone. This is a minumum sample size for meaningful statistics. We accurately compare strengths of different emission lines, their profiles and profile shifts, and continuum shapes, and use exist- ing radio & X-ray data to investigate some basic questions: Are there inclined accretion disks\? Is there stratification of the broad line region (BLR)\? Is there angle dependent and luminosity-dependent ionization of the BLR\? What is the origin of the Fe II emission\? What is the importance of line & continuum reddening\? How is X-ray & radio emission related to optical & UV properties\? The spectroscopy is being complemented by our VLA mapping, B, R & radio-core variability monitoring. In a recent preprint we demonstrate the usefulness of our optical-UV data in a first extensive study of the NLR in very luminous AGNs. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

The sample is described in \S 2, where Table 1 gives a list of the quasars. We indicate those with completed observations, and those hoped for in Cycle 3 but for which observing time is not guaranteed. We have selected quasars with luminosity in the extended radio emission, log L(ext), from 26.5 to 27.6 (erg/s, q=0, H=50 km/s/Mpc). For HST observations we plan to observe those with z < 1.8 and V < 18, which allows us to observe all Ly-alpha and CIV broad emission lines with HST. (The remainder of our sample of higher z either have been or will be observed from the ground.) This sample gives us a wide range of the ratio of core to extended radio emission from about 0.01 to 100 (at 6 cm rest wavelength), and a similar range in X-ray and radio core luminosity. In cycle 4 we propose to obtain FOS spectra for 18 quasars (depending on execution of Cycle 3 observations). We plan to cover rest wavelengths from 1160 A, to observed wavelengths of 3300 A or 4800 A, where the spectra will connect with our ground based observations. We plan to cover the region near 3200 - 3500 A with the G400H FOS grating setting in cases where important emission lines lie near the atmospheric cutoff. We aim for s/n = 19.5 per diode in the continuum in the region of strong emission lines. In this way we will cover all available strong lines with sufficient s/n to measure accurate line intensities, central wavelengths and line widths. We plan to use the 4.3 or 1'' aperture for spectrophotometry and to minimize background radiation. Spectrophotometry is important for the comparison of line strengths and spectral energy distributions between the HST and ground-based spectrophotometry. The point source resolution will be about 850 (~350 km/s) -- sufficient for the definition of broad line profiles, and probably sufficient, in nearly all cases, for taking into account the effects of Galactic, intergalactic, and intrinsic absorption features on our measurements of line and continuum emission. There is a very loose time constraint in that we want the quasars to be available in the night time sky as seen from the ground, at the time of FOS observations. It is extremely important to complete the sample as soon as possible so that the science, including our previous cycle observations can be investigated statistically in a timely way. Page 3 ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The heart of the project is the comparison of UV lines (Ly-alpha, NV 1240, 1400, CIV 1549, CIII]1909, Mg II 2798, Fe II 2000 - 3000 A) with optical and IR ground based spectra including hydrogen Balmer lines, Fe II 4570 and 5300 A etc, CIII], Mg II, He 4686, (and Paschen beta for a significant subset) that we are obtaining at McDonald, KPNO, CTIO and UKIRT. Therefore this project can only be done with HST and for a low to medium redshift sample. The statistical spectral analyses we are proposing would be impossible without HST, and so have never been attempted before. Why not IUE? The sensitivity, wavelength resolution and calibration accuracy are too low for the line wavelength, profile, and line and continuum flux measurements we are proposing. Number of objects: The total number of objects (52 in our HST program, supplemented by 3-4 archival spectra) is not very large considering the number of parameters we wish to investigate statistically, and our previous statistical studies of less complete samples suggest that we cannot do with fewer objects. We have intriguing correlations at the 2.6 to 3.3 sigma level with about 40% of our sample, and with the sample size we propose it should be possible to confirm or reject these correlations. The sample size is limited by the redshift, magnitude and extended radio luminosity selection criteria. The quasars must have good radio maps. Exposure time calculations: The correctness of our previous exposure time calculations is borne out by the SNR of our data already obtained (Fig.1). We have formed a composite quasar spectrum from below Ly alpha to beyond H-a, using quasars observed with IUE and at McDonald Observatory. We proceed for each quasar of our HST sample as follows: 1. Redshift the standard spectrum to that of the quasar. 2. Apply a standard Galactic reddening curve, 3. Scale this spectrum so that the V-magnitude in the observer's frame agrees with published values or our own photometry. 4. Multiply this spectrum by the expected HST FOS COSTAR response for different grating settings and cameras, and by the curve representing the wavelength dependent light losses in the 1'' aperture. Thus we convert the spectrum to the number of counts expected per diode per second. 5. We have then calculated the exposure time according to the FOS Hand Book formula, assuming standard observing procedures and for s/n = 19.5 per diode, in the continuum in the regions of strong emission lines. (1 diode is the instrumental resolution for the 1'' aperture.) 6. For the fainter objects we have checked the importance of the contribution of the Galactic background, using formulae from the previous FOS Handbook, and more recently the increased background contribution from the detector faceplate. We use the blue digicon rather than the red for G190H if an important emission line falls between about 1550 and 1700 A. We use G400H only when important emission lines fall close to the atmospheric cutoff and so cannot be observed accurately from the ground. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. THE SCHEDULING REQUIREMENTS ARE GIVEN SEPARATELY, IN A TABLE TOO LARGE TO APPEAR HERE. (This para added 1994 February for Tony Roman). Note that, within the table scheduling constraints, it is prefereable to group observations within a few days of New Moon, so that several objects can be observed efficiently in one dark-moon observing run. About 4-6 objects per month is manageable: 4 in summer, 6 in winter. They should not be at all the same right ascensions in a given month because then we can't spread the observations throughout a ground-based night. -- ----------------------------------------------------------------------------- We have the weak constraint that the HST observations should be made while the quasars are in the night sky as observed from the ground. We attempt to co- ordinate ground-based observations with the scheduled HST times, the quasi- simultaneity required depending on the degree of time variability. We are monitoring the flux variability from the ground. ------------------------------------------------------------------------------------ 6. Description of special calibration exposures.

THE SCHEDULING REQUIREMENTS ARE GIVEN SEPARATELY, IN A TABLE TOO LARGE TO APPEAR HERE. (This para added 1994 February for Tony Roman). Note that, within the table scheduling constraints, it is prefereable to group observations within a few days of New Moon, so that several objects can be observed efficiently in one dark-moon observing run. About 4-6 objects per month is manageable: 4 in summer, 6 in winter. They should not be at all the same right ascensions in a given month because then we can't spread the observations throughout a ground-based night. -- ----------------------------------------------------------------------------- We attempt to co-ordinate ground and space-based observations, but this does not fall into a `time-critical' category. We prefer HST observations to be scheduled near dark-moon time, when the quasars are available at night from the ground. It is preferable for the few highly variable objects to be observed as simultaneously as practicable. The ground-based spectroscopy will be obtained at McDonald Observatory, and also CTIO, KPNO, and UKIRT. An imminent improvement at McDonald will be the availability of a dual beam (red/blue) spectrograph with resolution similar to that of the G...H settings of the FOS, allowing the entire 3300 to 1 micron region to be observed simultaneously and efficiently (project of B.J. Wills and G.J. Hill). We are monitoring the photometric variability of our sample quasars (Netzer, Wills, Wills and Ferland - observations at Wise Observatory, Tel Aviv University, Israel), with some additional photometry from McDonald Observatory and CTIO, a program that will give us information on changes in optical flux density for improved estimates of HST exposure times (and for more astronomical reasons). We have measured accurate positions for nearly all quasars of our sample, using the STScI's GASP. Data rights: We would prefer to have the data released for archival use, as soon as we have had a chance to examine the sample statistically. In view of the spread over 4 cycles, we do not know if this is a reasonable request. Page 5 ------------------------------------------------------------------------------------ 9. Description of previous HST work. The Inner Regions of Quasars' (This project): Cycle 1 (2578), Cycle 1 (repeats...) (4052), Cycle 2 (3858), Cycle 2 repeats (5002), Cycle 3 (4502). 2306 `Physical Conditions in the NLR' (J.A. Baldwin. P.I.) 3982 `Physical Conditions in the NLR Part 2' (J.A. Baldwin. P.I.) The same investigators are involved in all of the above. Cycle 3: `Hidden QSOs in Ultraluminous IRAS AGN' (4351) -- P.I. B.Wills. This proposal is (unofficially?) a continuation of `The Inner Regions of Quasars' above. (See also the Scientific Justification where previous results are described in detail.) - We conclude that the narrow lines in the UV, in particular narrow L-alpha, are more than a factor of 5-10 weaker than can be accounted for by reasonable photo- ionization models. Comparison of H-alpha, H- beta and L-alpha strongly suggests significant dust reddening. This is the first extensive study of the NLR in high luminosity AGN. - Fortuitously, we discovered that the Egret telescope on the Compton Gamma Ray Observatory made gamma-ray observations of 3C279 simultaneously with our HST/FOS spectroscopy. HST and ground-based spectra reveal a steep UV spectrum and a high gamma-ray flux that is impossible to explain by beamed or unbeamed inverse Compton scattering. This paper also points out the extremely unusual strong red wing on some of the broad UV lines in this object. - A related ground-based program to study line profiles of H-beta, C IV and other lines is being carried out with graduate student Michael Brotherton. (This program is an important part of his PhD work). We find and discuss several striking new correlations that involve the density, ionization and dynamics of the BLR. This program is strongly related to, and supports, our HST astrophysics. Status of HST analysis: About 22 quasars out of our sample of 52 have been observed with HST (early May 1993). Data corrected for GIMP and instrumental background, along with appropriate flat fields, became available in May 1992 but correct flat fields were not available for all until February-March 1993. We have corrected all the data for spurious effects (spikes, dead and noisy diodes), and measured all line strengths and equivalent widths in both the HST and ground-based data. We have also compared all broad and narrow line profiles, and are currently making a special effort to tie down the wavelength scales using absorption features in the UV and optical (e.g. Mg II, Fe II interstellar lines). Our available observations make up about 40% of the complete sample. In the Scientific Justification we present trends that the data appear to show, but the analysis as far from complete as we need the Cycle 3 and 4 observations. However we expect to have a preprint by the end of May, concerning broad line profile comparisons, and trends with core-dominance and luminosity.
