TeV neutrinos and hard X-rays from relativistic reconnection in the corona of NGC 1068
Damiano F. G. Fiorillo, Maria Petropoulou, Luca Comisso +2
The recent discovery of astrophysical neutrinos from the Seyfert galaxy NGC 1068 suggests the presence of non-thermal protons within a compact "coronal" region close to the central…
A Hierarchical Framework for explaining the Cosmic Ray Spectrum using Diffusive Shock Acceleration
Roger Blandford, Paul Simeon, Noémie Globus +3
The hypothesis that the entire cosmic ray spectrum, from to energy, can be accounted for by diffusive shock acceleration on increasin…
Galactic Diffuse Neutrino Emission from Sources beyond the Discovery Horizon
Antonio Ambrosone, Kathrine Mørch Groth, Enrico Peretti +1
The IceCube Neutrino Observatory has recently reported strong evidence for neutrino emission from the Galactic plane. The signal is consistent with model predictions of diffuse emi…
Gamma-ray emission from the Seyfert galaxy NGC 4151: Multi-messenger implications for ultra-fast outflows
Enrico Peretti, Giada Peron, Francesco Tombesi +4
The nuclear activity typical of Seyfert galaxies can drive powerful winds where high-energy phenomena occur. In spite of their high power content, the number of such non-jetted act…
Reacceleration of Galactic Cosmic Rays Beyond the Knee at the Termination Shock of a Cosmic-Ray-Driven Galactic Wind
Payel Mukhopadhyay, Enrico Peretti, Noemie Globus +2
The origin of cosmic rays above the knee in the spectrum is an unsolved problem. We present a wind model in which interstellar gas flows along a non-rotating, expanding flux tube w…
Diffusive shock acceleration at EeV and associated multimessenger flux from ultra-fast outflows driven by Active Galactic Nuclei
Enrico Peretti, Alessandra Lamastra, Francesco Gabriele Saturni +4
Active galactic nuclei (AGN) can launch and sustain powerful winds featuring mildly relativistic velocity and wide opening angle. Such winds, known as ultra-fast outflows (UFOs), c…
