摘要:

我们报告的运动学研究的初步结果,三个塞弗特星系从附近的活动星系核的样本使用3D光谱观察。观测是在SAO RAS 6米望远镜的主焦点处进行的,使用了积分场摄谱仪MPFS和安装在多模式设备SCORPIO上的扫描法布里-珀罗干涉仪。在此基础上,建立了不同发射线上的单色图和速度场。我们在所有星系的环核区域都探测到了与射电喷流有关的核外流或电离气体运动。

英文摘要:

We report preliminary results of a kinematical study for three Seyfert galaxies selected from a sample of nearby active galactic nuclei observed using 3D spectroscopy. The observations were performed at the prime focus of the SAO RAS 6-m telescope with the integral-field spectrograph MPFS and with a scanning Fabry-Perot interferometer, installed on the multimode device SCORPIO. Based on these data, the monochromatic maps and velocity fields in different emission lines were constructed. We have detected a nuclear outflow or ionized gas motions associated with a radio jet in all galaxies circumnuclear regions.
