The events recorded by ARGO-YBJ in more than five years of data collection have been analyzed to determine the diffuse gamma-ray emission in the Galactic plane at Galactic longitudes 25{\deg} < l < 100{\deg} and Galactic latitudes . The energy range covered by this analysis, from ~350 GeV to ~2 TeV, allows the connection of the region explored by Fermi with the multi-TeV measurements carried out by Milagro. Our analysis has been focused on two selected regions of the Galactic plane, i.e., 40{\deg} < l < 100{\deg} and 65{\deg} < l < 85{\deg} (the Cygnus region), where Milagro observed an excess with respect to the predictions of current models. Great care has been taken in order to mask the most intense gamma-ray sources, including the TeV counterpart of the Cygnus cocoon recently identified by ARGO-YBJ, and to remove residual contributions. The ARGO-YBJ results do not show any excess at sub-TeV energies corresponding to the excess found by Milagro, and are consistent with the predictions of the Fermi model for the diffuse Galactic emission. From the measured energy distribution we derive spectral indices and the differential flux at 1 TeV of the diffuse gamma-ray emission in the sky regions investigated.

  1. Modelling Galactic neutrino emission: contributions from massive star clusters and interstellar cosmic rays

    astro-ph.HE 2026-06 unverdicted novelty 7.0

    Computes neutrino template maps from the Galactic Plane including star cluster emission, finding the cluster contribution may be non-negligible and consistent with IceCube best-fit templates.

  2. TeV-PeV Gamma-ray and Neutrino Emission in the Galactic Plane

    astro-ph.HE 2026-06 unverdicted novelty 3.0

    Alternative ISRF models produce only modest changes to the LHAASO diffuse gamma-ray fit; the associated pp neutrinos remain consistent with IceCube all-sky data and compatible with ANTARES/KM3NeT limits.

  3. IceCube Results and Perspective for Neutrinos from LHAASO Sources

    astro-ph.HE 2024-04 unverdicted novelty 2.0

    Reviews IceCube neutrino results, models Galactic plane flux from cosmic ray interactions with the interstellar medium, and discusses prospects for identifying PeVatrons via LHAASO sources.
