摘要
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 K$\alpha$, Fe XXV and Fe XXVI. These features indicate high-velocity ($\gtrsim15,000\,\rm{km\,s}^{-1}$ line-of-sight) material separated spanning $\sim$0.5 arcsec, within $\sim200$ pc of the nucleus. This outflow could have deprojected velocities $\sim12-28\times$ 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 ultra-fast outflows and AGN feedback on $\gtrsim$kpc scales.
