Continuation ID QUASARS & AGN SMC/ERO Sub Category QUASAR ABSORPTION ------------------------------------------------------------------------------------ 6. Principal Investigator Institution Country Telephone Sara Heap NASA/GSFC USA 301-286-5359 ------------------------------------------------------------------------------------ 7. Abstract The host galaxy of QSO 2130+099 is suspected to be a barred spiral (Hickson & Hutchings 1987, Heap 1986). We will use the unique imaging capabilities of the GHRS to map the nucleus of QSO 2130+099 in UV (1200- 3200A) light. These observations will (1) demonstrate that the GHRS' imaging capabilites have been recovered by COSTAR, and (2) provide the first high-resolution optical map of the nucleus/inner host galaxy of a quasar. THIS IS PART OF HEAP'S CYCLE-4 GTO PROGRAM. ------------------------------------------------------------------------------------ 8.

GENERAL FORM Proposal 5298 PI: Sara Heap Proposal Title: UV IMAGING OF THE NEARBY QSO 2130+099 HOST GALAXY ------------------------------------------------------------------------------------ 1. Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ Sara Heap NASA/GSFC USA ------------------------------------------------------------------------------------ 2. Scientific Justification. QSO 2130+099 is a nearby QSO with z=0.061 and V=14.4. Our recent studies of this object including image-deconvolution suggest that the host is a barred spiral with a central surface brightness, mu(B)=21.3 mag per sq. arcsec and a scale length of 4 kpc. Observing the inner region of this or any QSO poses two severe observational challenges: (1) high spatial resolution, and (2) high dynamic range. (The FOC coronograph won't work for this problem because it blots out the inner 0.5"?) The GHRS is the ONLY instrument on HST that can obtain direct images of the inner host galaxy. We therefore will use this unique capability to obtain UV maps of the nucleus/inner host galaxy with the GHRS. ------------------------------------------------------------------------------------ 3. Description of proposed observations. Schedule the GHRS observations in dark time, so that geocoronal Ly alpha emission doesn't swamp the target. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. Only the HST can give the required angular resolution and UV throughput. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. Lines 20-22 call for GHRS field maps that are not standard. The GHRS field maps should carried out during periods when there is NO JITTER. ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. Reduction and analysis of the data will be done at GSFC. ------------------------------------------------------------------------------------ 11.
