The Suzaku View of the Disk-Jet Connection in the Low Excitation Radio
  Galaxy NGC 6251
  We present results from an 87-ks Suzaku observation of the canonical
low-excitation radio galaxy (LERG) NGC 6251. We have previously suggested that
LERGs violate conventional AGN unification schemes: they may lack an obscuring
torus and are likely to accrete in a radiatively inefficient manner, with
almost all of the energy released by the accretion process being channeled into
powerful jets. We model the 0.5-20 keV Suzaku spectrum with a single power law
of photon index $\Gamma=1.82^{+0.04}_{-0.05}$, together with two collisionally
ionized plasma models whose parameters are consistent with the known galaxy-
and group-scale thermal emission. Our observations confirm that there are no
signatures of obscured, accretion-related X-ray emission in NGC 6251, and we
show that the luminosity of any such component must be substantially
sub-Eddington in nature.
