H I absorption, on the other hand, traces colder, denser gas that should be more confined in discrete clouds and perhaps discrete spiral arms. In addition, H I self-absorption (HISA) requires background H I emission at the same velocity as the foreground absorbing gas, thus introducing a much-needed constraint on the large-scale sightline geometry and kinematics. ...

... The circumnuclear GASEOUS disks are often decoupled from the circumnuclear stellar disks and are even stronger inclined to the outer disk planes; in fact, we have found a considerable `population' of inner polar rings. Inner gas polar rings are found as in spiral galaxies with the massive outer gas disks co-planar to the main symmetry planes (e.g. NGC 2841, Sil'chenko et al. 1997, and NGC 7217, Sil'chenko & Afanasiev 2000) as well in many lenticular galaxies (Fig. ...
