Radio AGN Feedback on Galaxy Scales: What can Athena show us?
Abstract
Over the last decade, we have used Chandra and XMM-Newton to study galaxy-scale, moderately powerful, jet-driven outflows in systems such as Centaurus A, NGC 3801, NGC 6764, Mrk 6, and the Circinus galaxy. Although they are difficult to observe from a technical standpoint, these outflows, with scales of tens to hundreds of kpc, have proven to be far more ubiquitous than previously suspected. Most importantly, they can transfer a substantial amount of energy to the ISM of the host galaxy, with the potential to radically and directly affect its gas dynamics and star formation processes. We review some of our past results to assess which outflow signatures Athena will be able to resolve, both spatially and spectroscopically, and what new light Athena can shed on these outflows, which are key to understanding AGN feedback on galaxy scales.
