Internal Kinematics of the Seyfert Galaxy Mkn938

—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.
