Abstract
Quasar outflows, which carry mass, energy, and momentum out of the quasar's central regions, are important forms of AGN feedback. Two major tracers for quasars ionized outflows are optical emission lines (e.g., [O III]) and UV broad absorption lines (BALs). But relationships between them are rarely studied and thus unclear. Robust estimates of outflow rates and sizes are also difficult. Therefore, it is crucial to gather both sets of data and analyze them jointly. Recently, an unbiased survey of quasar outflows from the Very Large Telescope (VLT) revealed various energetic outflow candidates from analyzing their BALs. We are proposing to adopt Gemini/NIFS IFU with AO to spatially resolve the [O III] outflows in one of their luminous quasars, then we will: 1) for the first time, reveal the relationship between BAL and [O III] outflows by contrasting the derived outflow rates, kinematics, and sizes, 2) quantify how ubiquitous are the [O III] outflows given the known strong AGN feedback, 3) study the morphology of [O III] outflows and how it alters the derived outflow rates. This pilot project will be a stepping stone for future complete studies of all energetic outflows from known VLT samples by Gemini observations.
