Investigating the Source of Planck-Detected AME: High-Resolution Observations at 15 GHz

Figure 8

Spectrum for G107.1+5.2 at 1° scales, from Planck, WMAP, and ancillary datasets (data points as in [3]). (a) Fitted with a two-component free-free model. The two free-free components are shown as red and blue dotted lines and the contribution from the thermal dust greybody as a purple dotted line. The combined model is shown as a solid green line. Model parameters are listed in Table 3. (b) Fitted with a free-free plus spinning dust model, the free-free component is shown as a green dotted line and the spinning dust component as a purple dotted line. The Rayleigh-Jeans tail of a CMB component is shown as a red dotted line, with the thermal dust greybody model excluded for clarity. The combined model is shown as a blue solid line.
