Although there is increasing speculation that the evolution of galaxy bulges may be regulated by AGN-induced outflows associated with the growth of the central supermassive black holes, the importance of AGN-induced outflows relative to those driven by starbursts has yet to be established observationally. Therefore we propose to use the unique capabilities of ACS/WFC and STIS on board HST to measure the spatial scales, structures and velocity gradients of the emission line outflows in a complete sample of nearby ULIRGs with optically-detected AGN. Combined with information derived from existing ground-based spectra, the HST data will be used to quantify the mass outflow rates and kinetic powers of the warm outflows for the first time in a significant sample of nearby ULIRGs. In this way we will establish whether the warm, AGN-driven outflows are energetically important and a major factor in the evolution of the host galaxies. Given that the ULIRGs represent low redshift analogues of the rapidly evolving galaxies now routinely detected in surveys of the distant Universe, the results will be important for our understanding of the co-evolution of supermassive black holes and their host galaxies at all redshifts. Only the HST is capable of the high spatial resolution required for this project at optical wavelengths. This project has two parts: imaging the near-nuclear emission line regions of nearby ULIRGs with Seyfert nuclei using ACS/WFC, and long-slit spectroscopy of the same targets using STIS to determine the spatially resolved emission line kinematics. *Note that the ACS imaging observations must be executed as early as possible in Cycle 20 because they are required to measure the slit position angles for the subsequent STIS long-slit spectroscopy observations.* The imaging part of this project will be done with ACS/WFC instrument, which is the only instrument on board HST that has the narrow-band filters required for sensitive emission line imaging observations, with minimum continuum contamination. This instrument is capable of resolving structures on the ~0.1 -- 0.5 arcsecond scale that we expect to be typical of the quasar-driven outflows in the target objects. In addition, we also expect to be able to use this instrument to determine the spatial offset between the emission line and continuum structures to an accuracy of much better than a pixel (<0.01 arcsec). In estimating the required exposure times we make the conservative assumption that the outflow regions (emitting the blueshifted [OIII]) cover an area of 0.25 sq.arcsec. With this assumption, and using the [OIII]5007,4959 fluxes from our ground-based data, the typical [OIII] surface brightness in the outflow regions in the faintest sources in our sample are 5x10^-14 erg cm^-2 s-1 arcsec^-2. We will use full frame redout to mitigate the effects of CTE and aid the reduction of the data in the pipeline (using pixel-based CTE correction and bias stripe removal, which only work for full frame readout) and, order to achieve the best possible image quality, we will use a standard three or four point box dither pattern for the emission line observations (N.B. the number of dither positions depends on the latitude of the source and how the exposures fits into the orbits). The total exposure time will be 1290 - 1440s (depending on declination) for the [OIII] observations of each object. We will use the FR551N or FR505N ramp filter (depending on redshift) for the [OIII] observations. Using the ACS ETC we estimate that we will achieve S/N > 30 per resolution element in a total exposure time of ~1300s (assuming 4 separate dithered exposures). This is entirely adequate for the science goals of our project. The S/N could be considerably greater than this if the outflow region is smaller than we have assumed. The continuum will make a negligible contribution to the noise in the continuum-subtracted emission line images, but, for an accurate structural analysis, it will be important to subtract a continuum image, since we estimate that the continuum will contribute up to 10 -- 30% of the total flux in each pixel. Continuum observations are also important for deriving the accurate positions of the continuum nuclei, and relating the emission line structures to the dust and stellar continuum structures in the nuclear regions. Based on the mean surface brightness of the continuum in the near-nuclear regions deduced from our ground-based spectra (5x10-17 erg cm^-2 s^-1 A-1 arcsec^-2), we will obtain S/N > 15 per resolution element for all our targets with a total exposure time of ~700s using the FR647M or F550M filter (depending on redshift) at a typical central wavelengths of 5500 - 6200A. This is entirely adequate for the purposes of continuum subtraction. For these observations a standard 2 point dither will be used to fit the exposures in the orbits For the STIS spectroscopic observations we will use the F750L or F430L grism (depending on redshift) to target the [OIII]5007,4959 emission lines with a 0.1 arcsec slit. This will give a spectral resolution of ~8A --- adequate to measure the kinematics of the emission line outflow components, which have typical line widths (FWHM) and velocity shifts of ~10A, (our previous experience with STIS observations shows that it will be possible to centroid the emission lines to an accuracy of better than 2A, with this setup). Using the STIS ETC we find that we will achieve our target S/N ( > 10, per spectral resolution element) in a total exposure time of 1200s (1 orbit including peakup and all other overheads), for a typical surface brightness in emission line outflow components of 5x10-14 erg cm^-2 s^-1 arcsec-2. Note that, although our observations are primarily aimed at the [OIII] emission lines, we will also obtain useful spatially-resolved information on the Halpha and [NII]6584,6548 emission lines. We will place the targets in the 52x0.1E1 aperture to help mitigate the CTE effects, and will use a 2 point sub-pixel dither of ~1.5 arcseconds along the slit (4 exposures in total including CR splits) to help remove hot pixels and improve spatial resolution. We will also include flat field observations to help remove fringing in the red. The slits for the spectroscopic observations will be oriented along specific PAs (with typical tolerance +/-5 degrees) designed to coincide with the structural axis of the main emission line regions, as determined from the ACS imaging observations. Therefore the STIS observations must be scheduled *after* the ACS observations. Following analysis of the ACS observations ----------------------------------- Although it was originally intended to spend 1 orbit on each of 8 objects for the specroscopic observations, following the ACS observations, it was decided to concentrate the spectroscopic effort on the 4 targets identified from the ACS observations to have extended structures in the near-nuclear regions with sufficiently high surface brightness to be readily measured with STIS. The change in the program has been approved by the TTRB. For the STIS observations, 2 objects will be observed for 3 orbits each (F13443+082, F14394+5332) with three parallel slit positions, and 2 objects will be observed for 1 orbit each (F13428+5608, F16156+0146) with one slit position. The ACS imaging observations also showed that the nuclear regions of the targets are too complex to allow direct target acquisition and slit peakup. Therefore it will be necessary to do the initial target acquisition and peakup on nearby stars (or in the case of F14394+5332 the compact nucleus of a nearby galaxy), then offset to the nuclear regions of the targets. The accurate positional offsets and ORIENTs have been determined directly from our ACS images. It is essential that ACS/WFC imaging observations are completed as early as possible in the cycle, because they are required to determine the slit position angles for the subsequent STIS spectroscopic observations.
