| Abstract: |
Neutral hydrogen (HI) is a key tracer of galactic structure and dynamics and responds most readily to perturbations caused by tidal disturbance and non-axisymmetric gravitational potentials, such as bars. Such perturbations have also been mooted as possible triggers of nuclear activity in galaxies, although no conclusive links have yet been established. I present here an HI imaging study of a heterogeneous sample of nine nearby Seyfert galaxies and describe plans for a new HI survey which aims to investigate the role of the host gas in triggering and fuelling of nuclear activity on a statistical basis. |
