Descripción
As a sub-set of activities within the THINGS (The HI Nearby Galaxy
Survey) collaboration we have used the HI maps of the complete set of
galaxies observed in the THINGS survey with the VLA to search for the
presence of high velocity clouds. Detections were made in 9% of the
cases, with a lower detection limit of just under 105 solar
masses. Given the column density limit of the survey, and assuming that
these clouds would have underlying structures comparable to those HVC's
around the Milky Way which are known not to be galactic fountain objects
(e.g. Complex C) we estimate that our detections would account for about
10% of the total HI masses that could be associated with the newly
detected cloudlets. We draw some tentative conclusions about the rate of
infall of HI onto the disks of the galaxies observed.
