A Suzaku Observation of MCG-2-58-22: Constraining the Geometry of the
  Circumnuclear Material
  We have analyzed a Suzaku long-look of the active galactic nucleus
MCG-2-58-22, a type 1.5 Seyfert with very little X-ray absorption in the line
of sight and prominent features arising from reflection off circumnuclear
material: the Fe line and Compton reflection hump. We place tight constraints
on the power law photon index (Gamma=1.80+/-0.02), the Compton reflection
strength (R=0.69+/-0.05), and the Fe K emission line energy centroid and width
(E=6.40+/-0.02 keV, v_FWHM < 7100 km/s). We find no significant evidence for
emission from strongly ionized Fe, nor for a strong, relativistically broadened
Fe line, indicating that perhaps there is no radiatively efficient accretion
disk very close in to the central black hole. In addition we test a new
self-consistent physical model from Murphy & Yaqoob, the "MYTorus" model,
consisting of a donut-shaped torus of material surrounding the central
illuminating source and producing both the Compton hump and the Fe K line
emission. From the application of this model we find that the observed spectrum
is consistent with a Compton-thick torus of material (column density
NH=3.6(+1.3/-0.8) x 10^24 cm^-2) lying outside of the line of sight to the
nucleus, leaving it bare of X-ray absorption in excess of the Galactic column.
We calculate that this material is sufficient to produce all of the Fe line
flux without the need for any flux contribution from additional Compton-thin
circumnuclear material.
