Abstract (from CDS):

We present Chandra ACIS imaging spectroscopy of the nucleus of the Seyfert 2 Galaxy Mrk 34. We identify spatially and spectrally resolved features in the band that includes Fe Kα, Fe XXV, and Fe XXVI. These features suggest high-velocity (≳15,000 km s–1 line-of-sight) material spanning ∼0.″5, within ∼200 pc of the nucleus. This outflow could have deprojected velocities ∼12-28× greater than the [O III]-emitting outflows, and could potentially dominate the kinetic power in the outflow. This emission may point to the origins of the optical and X-ray winds observed at larger radii, and could indicate a link between ultrafast outflows and AGN feedback on ≳kiloparsec scales.
