The Multiformity of the Evidence of Galaxy Interactions

We present the results of the spectral study of the some candidates to the polar-ring galaxies. New information about structure and kinematics of gaseous and stellar components was obtained using modern observing techniques such as integral field (3D) spectroscopy and high resolution long-slit spectroscopy. Detailed analysis of the data allowed us to conclude that investigated objects have complicated multi-component structure among which we can distinguish galaxies with classical polar rings, with circumnuclear polar disks, galaxies with warped gaseous disks and rings and even with stellar polar rings.
