5. Abstract

The role of associated absorption systems and dust obscuration close to the central
engines of AGN is not understood. Using the low-frequency selected Molonglo Quasar
Sample, we have discovered evidence for direct links between obscuration/absorption
and the radio properties of quasars that shed new light on the physics of radio
source evolution. To establish these results unequivocally, we require near-UV
spectroscopy with STIS on the HST of a complete set of 19 Molonglo quasars with
0.7<z<0.9. At these redshifts we will observe the restframe spectral region that
includes Ly-alpha and CIV. To detect reddening, we will measure UV-to-optical
continuum slopes and Ly-alpha/H-beta line ratios and will also search for absorption
systems close to the quasar redshift. These properties will be investigated as a
function of redshift, orientation and radio source size in order to test basic
models for dust obscuration near the central engines of AGN and also the physics of
radio-sourc e expansion.

  Observations Description
  ------------------------

     Observing Strategy: We will obtain near-UV spectroscopy using STIS of an
     unbiased subsample of 19 quasars, drawn from the Molonglo Quasar Sample (MQS).
     The MQS is the largest completely-identified sample of low-frequency (408 MHz)
     selected quasars (see Kapahi et al. 1998 for definition). Targets have been
     chosen from the MQS to cover the full range of radio properties --- they
     comprise 5 core-dominated flat-spectrum quasars, 5 compact steep-spectrum (CSS)
     quasars and 9 lobe-dominated quasars with radio linear sizes from tens of kpc
     to 1 Mpc. For these observations, we will use the G230L grating and the NUV-
     MAMA detector to achieve a spectral resolution of 1.5 Angstrom per pixel over
     the wavelength range 1570--3180 Angstrom. Our targets have been selected within
     the redshift range 0.75<z<0.94 for which Ly-alpha and C IV are both visible
     (including 2 CSS quasars where just Ly-alpha will be visible). The G230L+MAMA
     combination (rather than G230LB+CCD) was chosen for its slight ly greater
     sensitivity to point sources (using a 2-pixel slit width of 0.05"), with the
     added advantage of no read-out noise or cosmic rays. With this setup, we would
     reach a limiting magnitude of about 19 mag at 2500 Angstrom with a signal-to-
     noise ratio of 10 in one hour (or 10^-16 erg, cm^-2s^- 1Angstrom^-1arcsec^-2).
     Objects with the declinations of the MQS quasars (-20degrees>Dec>-30degrees)
     can be observed for 53 minutes per orbit. After guide star acquisition and peak
     -up (taking 6 minutes each), observing times of 2400 seconds per orbit are
     available. Thus to reach a signal-to-noise ratio of more than 10 in the
     continuum, we will observe those quasars with b_J<18 for 1 orbit and fainter
     targets for 2 orbits (we note that all targets will have strong emission
     lines). We therefore request a total of 34 orbits to complete the study.
