Among archive HST/FOS spectra, Ton34 shows an unusually steep FUV drop, equivalent to a powerlaw of index -5. At shorter wavelengths, only an extremely noisy IUE spectra exists. The FUV observations would provide us with a unique window to test whether Ton34 remains EUV deficient at shorter wavelengths or shows instead the onset of a second peak in the extreme (E)UV, explaining how photoionization can still account for its high excitation emission lines of CIV, OVI… With the STIS MAMA-NUV spectrum, we will also study and confirm whether low excitation EUV BLR lines such as the permitted lines of OII + OIII (835Å) or NIII (686Å) are present and as strong as reported from an earlier but noisy IUE spectrum (this would possibly favor shock excitation). Using archive optical spectra near the CIV region (from years 1988 and 2006), we recently showed that Ton34 is currently undergoing a strong BalQSO phase, the first case reported among bright quasars. A priority of the proposed STIS NUV observations will be to look for the presence of blueshifted absorption troughs near Ly-alpha or OIV (as well as any change in the continuum's sharp break) using the STIS/G430L spectrum.

Using earlier IUE (SWP+LWP) as well as FOS and 5m Palomar observations of TON34, we derived a SED for its continuum, which is used in ETC to determine integration times and properly evaluate (and rule out) possible risks for MAMA & COS. The strong emission line fluxes are manually added in the ETC form. The absolute flux calibration is provided by the FOS spectrum Y2IE0A04T obtained with grating G270H. http://archive.stsci.edu/cgi-bin/mastpreview?mission=hst&dataid=Y2IE0A04T We requested 4 orbits in total: -2 orbits with COS and grating G140L, -1 orbit with STIS MAMA NUV grating G230L, -1 orbit with STIS CCD grating G430L. The 3 visits are described as follows: --The two COS orbits will provide a S/Nresel >5 in the interval 1100 to 1500A. All four FP-POS will be covered. ACQ/SEARCH and ACQ/IMAGE will be used as it is a more efficient set-up. The resulting FUV spectrum will be used to check whether there is any flux recovery shortward of 1600A obsframe (600A restframe) and also to confirm the presence of (unusually) low excitation BLR lines (OIII, NIII...). --G230L: quasar TON34 is unusually EUV deprived, showing a sharp decline in flux shortward of 1000A restframe (~2900A obsframe). The STIS-MAMA-G230L integration will be used to characterize this flux decline down to the NUV wavelengths covered by COS-G130L. The expected S/Nresel is ~10 at 2400A. We expect to confirm the presence of other low excitation BLR lines in that range as well. The narrow longslit 52x0.1 will be used. G430L: using a SDSS spectrum that covered the CIV line, the quasar TON34 was shown to be the first bright quasar known to have becomed a BALQSO. In order to study the Ly-alpha region down to OIV, a NUV spectrum will be obtained with STIS-CCD-G430L. To manage CR, four integrations will be performed. The narrow longslit 52x0.1E1 will be used. A global S/Nresel of ~30 will be attained at 3200A after combining the 4 exposures. No real-time or special scheduling requirements. No special calibrations required. There are no objects brighter than V=21 within a radius of 1.1arcmin of TON34. Using the BOT tool in APT, the GALEX test reports no stars in the vicinity of target while the GSC2 test shows green status for the MAMA slit exposure and the COS exposure with grating. A red safety status of level 1 appears only for the COS exposures using ACQ and ACQ/IMAGE of the target (because V=15.80 and the count rate would be 11,170cnt/s if it was an OV star, but IT IS NOT an OV star). Using ETC and the known UV SED of target, we find with ETC that the expected count rate (15cnts/s) ismuch lower than the maximum recommended of 50cnts/s) AGN/QUASARS 12 false 0.0 0.0 false false false false SUPPORTED GALAXY BLR NLR QSO Position derived from 6th release of SDSS.
