Abstract:Polarized Galactic synchrotron emission is an undesirable foreground for cosmic microwave background (CMB) experiments observing at frequencies < 150 GHz. We perform a combined analysis of observational data at 1.4, 2.3, 23, 30 and 33 GHz to quantify the spatial variation of the polarized synchrotron spectral index, β pol , on ∼ 3.5 • scales. We compare results from different data combinations to address limitations and inconsistencies present in these public data, and form a composite map of β pol . Data qua… Show more
