Cold atoms in space: community workshop summary and proposed road-map
/ Alonso, Iván (Balearic Islands U.) ; Alpigiani, Cristiano (Washington U., Seattle) ; Altschul, Brett (South Carolina U.) ; Araújo, Henrique (Imperial Coll., London) ; Arduini, Gianluigi (CERN) ; Arlt, Jan (Aarhus U.) ; Badurina, Leonardo (King's Coll. London) ; Balaž, Antun (Belgrade, Inst. Phys.) ; Bandarupally, Satvika (Florence U. ; INFN, Florence) ; Barish, Barry C. (LIGO Lab., Caltech) et al.
We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportunities offered by their deployment in space, and the developments needed before cold atoms could be operated in space. The cold atom technologies discussed include atomic clocks, quantum gravimeters and accelerometers, and atom interferometers. [...]

High Energy Neutrino expectations from the Central Molecular Zone
/ Marinelli, Antonio (INFN, Pisa ; Pisa U.) ; Gaggero, Daniele (U. Amsterdam, GRAPPA) ; Grasso, Dario (INFN, Pisa ; Pisa U.) ; Taoso, Marco (Madrid, IFT) ; Urbano, Alfredo (CERN) ; Ventura, Sofia (INFN, Pisa ; Pisa U.)
The density of molecular gas in the central few hundreds parsecs of our Galaxy is estimated to be two orders of magnitude larger than the Galactic average. This, so called, Central Molecular Zone, represent a privileged target where to look for a signature of Galactic cosmic ray interactions. [...]

Evidences of unconventional cosmic ray propagation in gamma-ray and neutrino astronomy
/ Grasso, Dario (INFN, Pisa ; Pisa U.) ; Gaggero, Daniele (U. Amsterdam, GRAPPA) ; Marinelli, Antonio (Pisa U. ; INFN, Pisa) ; Taoso, Marco (Madrid, Autonoma U.) ; Urbano, D (CERN) ; Valli, Mauro (INFN, Rome ; Rome U.)
Several independent analyses of Fermi-LAT results found evidences of a spatial dependence of the cosmic ray (CR) proton spectral index which is not accounted for conventional models of CR transport in the Galaxy. We show that these results may have a relevant impact on the gamma-ray and neutrino diffuse emissions of the Galaxy above the TeV. [...]

The very high energy gamma-ray diffuse emission from the Galactic Center
/ Gaggero, Daniele (U. Amsterdam, GRAPPA) ; Grasso, Dario (INFN, Pisa ; Pisa U.) ; Marinelli, Antonio (Pisa U. ; INFN, Pisa) ; Taoso, Marco (Madrid, IFT) ; Urbano, Alfredo (CERN) ; Ventura, Sofia (INFN, Pisa ; Pisa U.)
We present a novel interpretation of the gamma-ray diffuse emission in the Galactic Center (GC) and the Central Molecular Zone (CMZ) regions. This is based on a scenario assuming a harder scaling of the diffusion coefficient with rigidity in the inner Galaxy which reproduces the radial dependence of the cosmic-ray (CR) spectral index recently inferred from Fermi-LAT.

Hard Cosmic Ray Sea in the Galactic Center: a consistent interpretation of H.E.S.S. and Fermi-LAT $\gamma$-ray data

We present a novel interpretation of the gamma-ray diffuse emission measured by H.E.S.S. in the Galactic Center (GC) region and the Galactic ridge. [...]

Gamma-ray and neutrino diffuse emissions of the Galaxy above the TeV
/ Gaggero, Daniele (U. Amsterdam, GRAPPA) ; Grasso, Dario (INFN, Pisa ; Pisa U.) ; Marinelli, Antonio (INFN, Pisa ; Pisa U.) ; Urbano, Alfredo (CERN) ; Valli, Mauro (INFN, Trieste ; SISSA, Trieste)
As recently shown, Fermi-LAT measurements of the diffuse gamma-ray emission from the Galaxy favor the presence of a smooth softening in the primary cosmic-ray spectrum with increasing Galactocentric distance. This result can be interpreted in terms of a spatial-dependent rigidity scaling of the diffusion coefficient. [...]

The gamma-ray and neutrino sky: a consistent picture of Fermi-LAT, H.E.S.S., Milagro, and IceCube results
/ Gaggero, Daniele (INFN, Pisa ; SISSA, Trieste ; U. Amsterdam, GRAPPA) ; Grasso, Dario (INFN, Pisa ; Pisa U.) ; Marinelli, Antonio (INFN, Pisa ; Pisa U.) ; Urbano, Alfredo (INFN, Trieste ; SISSA, Trieste ; CERN) ; Valli, Mauro (INFN, Trieste ; SISSA, Trieste)
In this Letter we propose a novel interpretation of the anomalous TeV gamma-ray diffuse emission observed by Milagro in the inner Galactic plane consistent with the signal reported by H.E.S.S. in the Galactic ridge; remarkably, our picture also accounts for a relevant portion of the neutrino flux measured by IceCube.
