Constraints on the spectral index of polarized synchrotron emission from WMAP and Faraday-corrected S-PASS data

U. Fuskeland, K. J. Andersen, R. Aurlien +8

We constrain the spectral index of polarized synchrotron emission, ${\beta }_s$, by correlating the recently released 2.3 GHz S-Band Polarization All Sky Survey (S-PASS) data with the 23…
