view (Figure 2). Mass and energy are flowing, with mass outflow rates typically 10
times the star-formation rate, though it is
not certain whether this material will permanently escape to the galaxy halo.
Disentangling the source of the outflow
as either star formation or the AGN is difficult. There are no obvious morphological differences between the two. Energyscaling arguments alone are insufficient,
since the underlying power — luminosity from star formation, AGN, and related
radio sources — is generally correlated.
A mix of all sources may be important.
Nonetheless, these results are broadly
consistent with theoretical models of
AGN-driven outfl
