The results of panoramic spectroscopy fulfilled with the scanning Fabry–Perot interferometer are presented for a small sample of compact galaxy groups. Several cases of intergalactic ionized-gas flows are found. By analyzing line-of-sight gas velocities in these flows, we discuss their origin and their possible importance for cold-gas outer accretion onto the galaxies—group members.
O. K. Silchenko (Mon,) studied this question.
