QUIJOTE scientific results - XIX. New constraints on the synchrotron spectral index using a semi-blind component separation method

Open Access

Fig. 9.

Synchrotron Stokes Q_{ν_s} (first panel) and U_{ν_s} (second panel) maps at 22.8 GHz recovered from the cPILC component separation method using the QUIJOTE MFI 11 and 13 GHz combined map, WMAP K and Ka bands and Planck LFI 30 GHz. The Stokes parameters corresponding to the spectral index modulated synchrotron amplitudes, Q_{ν_s}β_s, U_{ν_s}β_s obtained from component separation are shown in the third and fourth panels respectively. All maps are at FWHM = 2° at N_side = 64.
