Title: A multi-wavelength study of the host environment of SMBHB 4C+37.11

4C+37.11, at z = 0.055, shows two compact radio nuclei, imaged by very long baseline interferometry at 7 mas separation, making it the closest known resolved supermassive black hole binary (SMBHB). An important question is whether this unique object is young and was caught on the way to a gravitational in-spiral and merger, or has 'stalled' at 7 pc. We describe new radio/optical/X-ray observations of the massive host and its surrounding X-ray halo. These data reveal X-ray/optical channels following the radio outflow and large scale edges in the X-ray halo. These structures are promising targets for further study which should elucidate their relationship to the unique SMBHB core.
