A multi-messenger view of the Milky Way galaxy, centered on the galactic center
and viewed in galactic coordinates. Each panel shows the entire Galactic plane in a band of
±15◦ in galactic latitude, with each panel having a unique color scale. The panels, from top to bottom, are: 1) view in the optical range, which is partly obscured by clouds of
gas and dust that absorb optical photons, 2) the integrated flux in gamma
rays as seen by the Fermi-LAT 12 year survey, 3) emission template
for the expected neutrino flux, taken to match the template from Fermi-LAT measurements, 4) emission template from panel 3 convolved with the IceCube detector acceptance for cascade-like neutrino events and 5) pre-trial significance of the all-sky scan for point-like
sources using the cascade neutrino event sample in the same band of the Galactic plane.
