QUIJOTE scientific results -- X. Spatial variations of Anomalous Microwave Emission along the Galactic plane

Understand

Anomalous Microwave Emission (AME) is an important emission component between 10 and 60 GHz that is not yet fully understood.

• It seems to be ubiquituous in our Galaxy and is observed at a broad range of angular scales.
• Here we use the new QUIJOTE-MFI wide survey data at 11, 13, 17 and 19 GHz to constrain the AME in the Galactic plane ($|b|<10^\circ$) on degree scales.
• We built the spectral energy distribution between 0.408 and 3000 GHz for each of the 5309 0.9$^\circ$ pixels in the Galactic plane, and fitted a parametric model by considering five emission components: synchrotron, free-free, AME, thermal dust and CMB anisotropies.
