Top: microwave haze at Planck 30 GHz (red, −12 μK < ΔT_CMB< 30 μK) and 44 GHz (yellow, 12 μK < ΔT_CMB< 40 μK). Bottom: the same, but including the Fermi 2–5 GeV haze/bubbles of Dobler et al. (2010) (blue, 1.05 < intensity (keV cm^-2 s^-1 sr^-1) < 1.25; see their Fig. 11). The spatial correspondence between the two is excellent, particularly at low southern Galactic latitude, suggesting that this is a multi-wavelength view of the same underlying physical mechanism.
