We review the present observational knowledge on the spatial distribution and the physical state of the different (molecular, atomic and ionized) components of the interstellar gas in the innermost 3 kpc of our Galaxy -- a region which we refer to as the interstellar Galactic bulge, to distinguish it from its stellar counterpart. We try to interpret the observations in the framework of recent dynamical models of interstellar gas flows in the gravitational potential of a barred galaxy. Finally, relying on both the relevant observations and their theoretical interpretation, we propose a model for the space-averaged density of each component of the interstellar gas in the interstellar Galactic bulge.

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

    astro-ph.HE 2026-06 unverdicted novelty 3.0 of 10

    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.

  2. Supermassive black holes and their surroundings: MeV signatures

    astro-ph.HE 2025-07 unverdicted novelty 2.0 of 10

    A review of open questions in supermassive black hole physics that argues the MeV gamma-ray band is the critical missing observational window.
