Mergers of Galaxies from an HI Perspective

الأصل · EN

HI spectral line mapping studies are a unique probe of morphologically peculiar systems. Not only does HI imaging often reveal peculiarities that are totally unsuspected at optical wavelengths, but it opens a kinematic window into the outer dynamics of these systems that is unmatched at any other wavelength. In this review I attempt to summarize what we have learned from such studies, and what we may hope to learn from them in the future.
