PI: Prof. Steven Kraemer Catholic University of America Y CoI: Dr. T. Jane Turner University of Maryland Baltimore County N CoI: Dr. D. Michael Crenshaw Georgia State University Research N Foundation ------------------------------------------------------------------------------------ Abstract AGN feedback, in the form of winds or jets, is likely the mechanism that connects the growth of galactic bulges and their super-massive black holes. AGN-driven winds are most directly studied at the spatial scale of the narrow line region (NLR), but little is known of NLR X-ray emitting gas, which may be the dominant component in mass outflows. Given its brightness and orientation, the Seyfert 1 galaxy NGC 4151 is one of the few AGN for which we can resolve the X-ray NLR. We will obtain a 250 ksec Chandra/HETG observation, at a roll angle which will permit us to map the kinematics and ionization structure of the high-ionization gas. We will use these data to determine the mass outflow rate and kinetic luminosity of the X-ray gas, and, thus, its role in AGN feedback. ------------------------------------------------------------------------------------ Observations Description ------------------------ we will obtain {\it HST}/STIS spectra of the nucleus of NGC~4151 with the E140M grating to cover the important UV absorption lines in the range 1150 -- 1710 \AA~ at a velocity resolution of $\sim$7 km s$^{-1}$ (NGC~4151 is the only Seyfert galaxy too bright to be observed by COS). Using the STIS exposure time calculator and the average continuum flux of 2.8 $\times$ 10$^{-13}$ ergs s$^{-1}$ cm$^{-2}$ \AA$^{-1}$~ at 1345 \AA, we will obtain a S/N $\approx$ 5 per resolution element with an exposure time of 5100 s (2 orbits), similar to spectra we have obtained of this AGN over the years.
