Abstract—We report the results of a detailed study of the central part of the Seyfert galaxy Mkn938. Observational data were obtained with the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences using integral field spectrograph MPFS and a scanning Fabry–Perot interferometer. Mkn938 is interesting for being a result of a merger of two gas-rich galaxies, and we observe the final stage of this merger accompanied with an extremely powerful burst of star formation and nuclear activity. Our analysis of the kinematics of gas and stars revealed the presence of gas outflow in the circumnuclear region Mkn938 with velocities ranging from −370 to −480 km s⁻¹, and allowed us for the first time to map the high-velocity galactic wind in Na D absorption line on large spatial scale.

赛弗特银河Mkn938的内部运动学

摘要—我们报告了对塞弗特星系Mkn938中心部分进行详细研究的结果。观测数据是使用俄罗斯科学院特殊天文台的6米望远镜使用积分场光谱仪MPFS和扫描法布里-珀罗干涉仪获得的。Mkn938很有趣，因为它是两个富含气体的星系合并的结果，我们观察到合并的最后阶段伴随着极其强大的恒星形成和核活动爆发。我们对气体和恒星运动的分析表明，在Mkn938周围核区域存在气体流出，速度范围为-370至-480 km s ^-1，这是我们第一次在大空间尺度上绘制Na D吸收线中的高速银河风。
