Abstract:
Radio outflows of active galactic nuclei (AGNs) are invoked in
cosmological models as a key feedback mechanism in the latest phases
of massive galaxy formation. Recently, it has been suggested that the
two major radio AGN populations-the powerful high-excitation, and the
weak low-excitation radio AGNs (HERAGN and LERAGN,
respectively)-represent two earlier and later stages of massive galaxy
buildup. To test this, here we make use of a local (0.04<z<0.1)
sample of ∼500 radio AGNs with available optical spectroscopy, drawn
from the FIRST, NVSS, SDSS, and 3CRR surveys.
