The Complex North Transition Region of Centaurus A: A Galactic Wind
  We present deep GALEX images of NGC 5128, the parent galaxy of Centaurus A.
We detect a striking "weather ribbon" of Far-UV and H$\alpha$ emission, which
extends more than 35 kpc northeast of the galaxy. The ribbon is associated with
a knotty ridge of radio/X-ray emission, and is an extension of the previously
known string of optical emission-line filaments. Many phenomena in the region
are too short-lived to have survived transit out from the inner galaxy;
something must be driving them locally. We also detect Far-UV emission from the
galaxy's central dust lane. Combining this with previous radio and Far-IR
measurements, we infer an active starburst in the central galaxy, which is
currently forming stars at $\sim 2 M_{sun}$yr$^{-1}$, and has been doing so for
50-100Myr. If the wind from this starburst is enhanced by energy and mass
driven out from the AGN, the powerful augmented wind can be the driver needed
for the northern weather system. We argue that both the diverse weather system,
and the enhanced radio emission in the same region, result from the wind's
encounter with cool gas left by one of the recent merger/encounter events in
the history of NGC 5128.
