O'Dea Rochester Institute of Technology N ------------------------------------------------------------------------------------ Abstract AGN feedback is now routinely included in both galaxy evolution models and cosmological simulations yet large uncertainties remain about the most important parameters, such as the mass outflow rates, bulk kinetic powers and the dominant outflow driving mechanisms. In order to address this issue, we propose to make HST ACS/WFC observations of a small, complete sample of compact (young) radio sources which have clear evidence for strong emission line outflows. Compact radio sources are ideal sources for studying AGN feedback as in addition to begin young, recently triggered AGN, all potential outflow drivers are present in these sources (AGN winds/starbursts/radio jets). We will use the unique capablilities of HST ACS/WFC to map the outflowing regions with high spatial resolution to determine the dominant outflow driving mechanism. Furthermore, the morphological information, in combination with our new high resolution VLT/X-Shooter spectra (which cover the entire optical - near-IR wavelength range simultaneously), will allow us to accurately calculate the outflow energetics in these sources. Such studies are crucial for determining whether AGN feedback in real galaxies can achieve the requirements made by simulations. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will use the ramp filters to observe the [O III]4959, 5007 emission line and a corresponding line free continuum region in two powerful compact radio sources. The main science goal of the proposal is to map the regions of line emission in order to determine the locations, sizes and structures relative to the host galaxies and their radio emission in these sources. The size information will be combined with our existing spectroscopy results to calculate the energetics of the AGN feedback. The morphology and location of the emission line region in relation to the radio source will help us to understand what the dominant gas ionisation mech anism is. We will use th standard ACS 4-point dither to ensure the best possible sampling and resolve the compact emission line regions.
