发光的QSO Mrk 231中大量千秒级外流的积分场光谱学
Integral Field Spectroscopy of Massive, Kiloparsec-Scale Outflows in the Infrared-Luminous QSO Mrk 231
摘要：
类星体（QSO）/合并Mrk 231可以说是研究QSO反馈的最近和最好的实验室。它有几个外流，包括宽线风，射电喷流和一个知之甚少的kpc尺度外流。在这封信中，我们提出了积分场光谱从双子望远镜，代表了第一个明确的检测广角，千秒差距规模流出一个强大的类星体。使用中性气体吸收，我们表明，核区域的主机流出蓝移速度达到1100公里/秒，延伸2-3千秒差距，从核在天空平面的各个方向。一个射电喷流撞击了核心以北的外流，使其加速到更高的速度（高达1400 km/s）。最后，在核心以南3.5 kpc处，恒星形成同时为外流提供动力，其速度仅为570 km/s。蓝移的电离气体也在较低速度和较小尺度的核周围被检测到。外流的质量和能量通量大于恒星形成速率的2.5倍，大于活动星系核光度的0.7%，符合类星体的负反馈模型。
英文摘要：
The quasi-stellar object (QSO)/merger Mrk 231 is arguably the nearest and best laboratory for studying QSO feedback. It hosts several outflows, including broad-line winds, radio jets, and a poorly-understood kpc scale outflow. In this Letter, we present integral field spectroscopy from the Gemini telescope that represents the first unambiguous detection of a wide-angle, kpc scale outflow from a powerful QSO. Using neutral gas absorption, we show that the nuclear region hosts an outflow with blueshifted velocities reaching 1100 km/s, extending 2-3 kpc from the nucleus in all directions in the plane of the sky. A radio jet impacts the outflow north of the nucleus, accelerating it to even higher velocities (up to 1400 km/s). Finally, 3.5 kpc south of the nucleus, star formation is simultaneously powering an outflow that reaches more modest velocities of only 570 km/s. Blueshifted ionized gas is also detected around the nucleus at lower velocities and smaller scales. The mass and energy flux from the outflow are >~2.5 times the star formation rate and >~0.7% of the active galactic nucleus luminosity, consistent with negative feedback models of QSOs.
