A UFO Seen Edge-on? : resolving Ultrafast Outflow Emission on ∼200 pc Scales with Chandra in the Active Nucleus of Mrk 34
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 ∼0farcs5, wit...

| Resumo: | 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 ∼0farcs5, 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. |
