论文摘要
我们研究了附近塞弗特星系中心区域的星际培养基（ISM）特性，其特征在于属于Magnum调查的突出的圆锥形或双孔外流，通过利用前所未有的敏感性，空间和光谱覆盖在非常大的远程计算机上的集成场谱仪的空间和光谱覆盖。我们开发了一种基于气体和恒星运动学的新方法，从盘中的气体中排出高速气体的高速气体，以在空间上跟踪其ISM性质的差异。这使我们能够在扩展流出中揭示电离结构的存在，可以用不同的光电子化和冲击条件来解释，并在样品的星系中追踪流出引起的恒星形成（''阳性'反馈）的试探性证据。
We investigated the interstellar medium (ISM) properties in the central regions of nearby Seyfert galaxies characterised by prominent conical or bi-conical outflows belonging to the MAGNUM survey by exploiting the unprecedented sensitivity, spatial and spectral coverage of the integral field spectrograph MUSE at the Very Large Telescope. We developed a novel approach based on the gas and stars kinematics to disentangle high-velocity gas in the outflow from gas in the disc to spatially track the differences in their ISM properties. This allowed us to reveal the presence of an ionisation structure within the extended outflows that can be interpreted with different photoionisation and shock conditions, and to trace tentative evidence of outflow-induced star formation (''positive'' feedback) in a galaxy of the sample, Centaurus A.
