Data-driven modeling of Galactic diffuse emission with multi-wavelength observations
Xi Liu, Xiaodong Li, Sujie Lin +4
We present a data-driven investigation of Galactic diffuse emission. Using multi-frequency Planck radio/microwave maps (30-857 GHz) and Fermi-LAT gamma-ray data (50 MeV-814 GeV), w…
