A characterization of the diffuse Galactic emissions in the anti-center
  of the Galaxy
  Using the Archeops and WMAP data we perform a study of the anti-center
Galactic diffuse emissions - thermal dust, synchrotron, free-free and anomalous
emission - at degree scales. The high frequency data are used to infer the
thermal dust electromagnetic spectrum and spatial distribution allowing us to
precisely subtract this component at lower frequencies. After subtraction of
the thermal dust component a mixture of standard synchrotron and free-free
emissions does not account for the residuals at these low frequencies.
Including the all-sky 408 MHz Haslam data we find evidences for anomalous
emission with a spectral index of 2.5 in TRJ units. However, we are not able to
conclude regarding the nature of this anomalous emission in this region. For
the purpose, data between 408 MHz and 20 GHz covering the same sky region are
needed.
