我们对NGC 7592进行了三维光谱研究，NGC 7592是一个由三个星系组成的红外发光相互作用系统，其中一个星系包含一个Seyfert 2核。的窄带图像和[Oiii]使用具有可调谐滤波器的成像法布里-珀罗干涉仪获得。还通过在垂直于狭缝的方向上的狭缝扫描进行面积分光观察。塞弗特核被发现被一个盘状或环状的多节恒星形成区所包围。沿着盘或环的轴，一个高度电离的双极气体区域被确定。根据运动学分析，这个系统由两个星系组成，其中一个视核被认为是属于一个星系的巨大Hii区域。这一结果得到了近红外的形态学特性的支持。此外，有人提出，一个星系是早期型螺旋星系，而另一个是晚期型螺旋星系，两个星系在各自的恒星形成区域的分布上显示出显着的差异。这种差异的原因与两个星系之间的动力学扰动有关。
We performed a tridimensional spectroscopic study of NGC 7592, an infrared-luminous interacting system of three galaxies, one of which contains a Seyfert 2 nucleus. Narrow-band images ofand [Oiii] were obtained using an imaging Fabry–Perot interferometer with a tunable filter. An area-spectroscopic observation was also made by a slit scan in a direction perpendicular to the slit. The Seyfert nucleus was found to be surrounded by a knotty star-forming region of disk- or ring-shape. Along the axis of the disk or ring, a highly-ionized bipolar gaseous region was identified. From kinematical analyses, it has been suggested that this system is composed of two galaxies; one apparent nucleus is considered to be a giant Hiiregion belonging to one galaxy. This result is supported by the morphological properties in near-infrared. Further, it has been suggested that one galaxy is an early-type spiral, whereas the other is a late-type one, and the two galaxies show a marked difference in the distribution of the star-forming regions within each. The cause of the difference was argued in relation with the dynamical perturbation between the two galaxies.
