论文摘要
我们介绍了对Seyfert Galaxy MKN 938的中央部分进行详细研究的结果。使用整体场景光谱仪MPF和扫描式Fabry-Perot-Perot-Perot-Pertrot-therferfermoinser，使用俄罗斯科学学院特殊天体物理学学院的6 m望远镜获得了观察数据。 MKN 938是由两个富含气体的星系合并的结果而有趣的，我们观察到这种相互作用的最后阶段伴随着极力强大的恒星形成和核活动。我们对气体和恒星运动学的分析揭示了在核心区域MKN 938中存在气体流出的速度，速度从-370到-480 km/s，并首次允许我们绘制该银河系中NAD吸收量的高速度银河系风中的高速度银河系风。
We present the results of a detailed study of the central part of the Seyfert galaxy Mkn 938. 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. Mkn 938 is interesting for being a result of a merger of two gas-rich galaxies, and we observe the final stage of this interaction 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 Mkn 938 with velocities ranging from -370 to -480 km/s, and allowed us for the first time to map the high-velocity galactic wind in NaD absorption line on large spatial scale in this galaxy.
