| Abstract |
Asymmetry is a common characteristic of many disk galaxies, but we have
little understanding of its causes. In this contribution we look at the
H I properties of a sample of Magellanic spirals, some of the most
lopsided galaxies in the local Universe, and a sample of isolated
spirals. In neither case do we see evidence of a link between the
presence of a companion and asymmetry; indeed, asymmetry persists even
in the absence of a companion or evidence of a recent interaction. These
results suggest that once it arises, asymmetry may be a very long-lived
characteristic of disk galaxies. |
