WebThe WMAP team has produced a foreground map that can account for most of the low-frequency Galactic microwave emission in the WMAP maps, tentatively interpreting it as synchrotron emission. Finkbeiner and collaborators have challenged these conclusions, arguing that the WMAP team “synchrotron” template is in fact not dominated by ... WebMar 8, 2010 · The foreground diffuse galactic emission is modeled by a cosmic-ray propagation model, with parameters optimized to fit various cosmic-ray and gamma-ray data sets, using maps of hydrogen in its various phases in the interstellar medium to fit gamma-ray emission from cosmic-ray interactions.

WebJun 16, 2024 · Such a feature, coupling with the foreground emission, biases the reconstruction of the signal across frequency, potentially impacting the cosmological analysis. We show that this effect is constrained to a narrow region in k ∥ space and can be reduced if the maps are carefully re-smoothed to a common lower resolution.
