论文摘要
我们介绍了Seyfert 2 Galaxy MRK 34核的$ Chandra $ acis成像光谱。我们在频段中以空间和光谱分辨的特征在内，其中包括Fe K $α$，Fe XXV和Fe XXVI。这些功能表明高速度（$ \ gtrsim15,000 \，\ rm {km \，s}^{ - 1} $ sight Line of-sight）材料分离跨越$ \ sim $ 0.5 arcsec，$ \ sim200 nucleus的$ \ sim200 $ PC。此流出的速度可能比[O III]发出的流量大，$ \ sim12-28 \ times $ $ $，并且可能在流出中的动力学能力占主导地位。这种发射可能指出在较大半径处观察到的光学和X射线风的起源，并且可以指示超快速流出和$ \ gtrsim $ kpc量表的AGN反馈之间的联系。
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$α$, 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.
