  We present new Hubble, Gemini-S, and Chandra observations of the radio galaxy
0313-192, which hosts a 350-kpc double source and jets, even though previous
data have suggested that it is a spiral galaxy. We measure the bulge scale and
luminosity, radial and vertical profiles of disk starlight, and consider the
distributions of H II regions and absorbing dust. In each case, the HST data
confirm its classification as an edge-on spiral galaxy, the only such system
known to produce such an extended radio source of this kind. The Gemini near-IR
images and Chandra spectral fit reveal a strongly obscured central AGN, seen
through the entire ISM path length of the disk and showing X-ray evidence of
additional absorption from warm or dense material close to the central object.
We consider several possible mechanisms for producing such a rare combination
of AGN and host properties, some combination of which may be at work. These
include an unusually luminous bulge (suggesting a black hole of mass 0.5-0.9
billion solar masses), orientation of the jets near the pole of the gas-rich
disk, and some evidence of a weak gravitational interaction which has warped
the disk and could have enhanced fuelling of the central engine. An X-ray
counterpart of the kiloparsec-scale radio jet emerges to the south;
jet/counterjet limits in both radio and X-ray allow them to be symmetric if
seen more than 15 degrees from the plane of the sky, still consistent with the
jet axes being within ~30 degrees of the poles of the gas-rich galaxy disk. A
linear or disklike emission-line structure is seen around thenucleus, inclined
by ~20 degrees to the stellar disk but nearly perpendicular to the jets; this
may represent the aftermath of a galaxy encounter, where gas is photoionized by
the nuclear continuum.
