  Using 7-year data from the Wilkinson Microwave Anisotropy Probe I identify a
sharp "edge" in the microwave haze at high Galactic latitude (35 deg < |b| < 55
deg) that is spatially coincident with the edge of the "Fermi Haze/Bubbles".
This finding proves conclusively that the edge in the gamma-rays is real (and
not a processing artifact), demonstrates explicitly that the microwave haze and
the gamma-ray bubbles are indeed the same structure observed at multiple
wavelengths, and strongly supports the interpretation of the microwave haze as
a separate component of Galactic synchrotron (likely generated by a transient
event) as opposed to a simple variation of the spectral index of disk
synchrotron. In addition, combining these data sets allows for the first
determination of the magnetic field within a radio bubble using microwaves and
gamma-rays by taking advantage of the fact that the inverse Compton gamma-rays
are primarily generated by scattering of CMB photons at these latitudes, thus
minimizing uncertainty in the target radiation field. Assuming uniform volume
emissivity, I find that the magnetic field within our Galactic
microwave/gamma-ray bubbles is ~5 muG above 6 kpc off of the Galactic plane.
