Between the Galactic Disk and Halo - Dr Jay Lockman Colloquium

There has been much recent research into the
boundry between the Milky Way's gaseous disk and its hot halo.
In this talk I'll describe study of neutral hydrogen in this region,
where new observations reveal a wealth of detail and many genuine
surprises. I'll describe observations of an enormous superbubble
of neutral and ionized gas that has been discovered in the inner Galaxy,
and review information on the population of rather small HI clouds which
seem to pervade the ISM away from the plane. For all the new data,
we still can't be sure how this material got so far from the Galactic
plane, why it seems to be cruising along in nearly-normal Galactic rotation,
and whether it is rising, falling, or standing still.
