Extended X-ray Emission From a Quasar-driven Superbubble
Abstract
We propose to look for the X-ray component of a bona-fide quasar-driven wind, manifested as a 20 kpc-scale superbubble in the warm ionized gas. With ALMA and JVLA observations, we have ruled out star formation or a radio jet as the source of the outflow, and we have detected very soft (<1 keV) X-ray photons spatially coincident with the superbubble. With our existing 20 ks observation, we cannot determine whether the X-rays arise from the hot outflow or photoionized gas. With an additional 80ks observation (100 ks total), we will use the X-ray morphology and spectrum to distinguish these two possibilities. A single-orbit HST observation will allow us to both build a pure emission line map of the outflow and (via scattered light) teach us about the ambient density in the outflow.
