Constraints on heavy decaying dark matter from 570 days of LHAASO observations
The LHAASO Collaboration, Zhen Cao, F. Aharonian +276
The Kilometer Square Array~(KM2A) of the Large High Altitude Air Shower Observatory (LHAASO) aims at surveying the northern gamma-ray sky at energies above 10 TeV with unprecedente…
Starburst Nuclei as Light Dark Matter Laboratories
Antonio Ambrosone, Marco Chianese, Damiano F. G. Fiorillo +2
Starburst galaxies are well-motivated astrophysical emitters of high-energy gamma-rays. They are well-known cosmic-ray "reservoirs", thanks to their large magnetic fields which con…
Constraining axion-like particles with the diffuse gamma-ray flux measured by the Large High Altitude Air Shower Observatory
Leonardo Mastrototaro, Pierluca Carenza, Marco Chianese +4
The detection of very high-energy neutrinos by IceCube experiment supports the existence of a comparable gamma-ray counterpart from the same cosmic accelerators. Under the likely a…
Multi-messenger High-Energy Signatures of Decaying Dark Matter and the Effect of Background Light
Barbara Skrzypek, Marco Chianese, Carlos Argüelles Delgado
The IceCube Neutrino Observatory at the South Pole has measured astrophysical neutrinos using through-going and starting events in the TeV to PeV energy range. The origin of these…
Observable Signatures of Cosmic Rays Transport in Starburst Galaxies on Gamma-ray and Neutrino Observations
A. Ambrosone, M. Chianese, D. F. G. Fiorillo +2
The gamma-ray emission from Starburst and Starforming Galaxies (SBGs and SFGs) strongly suggest a correlation between star-forming activity and gamma-ray luminosity. However, the v…
Electron scattering of light new particles from evaporating primordial black holes
Roberta Calabrese, Marco Chianese, Damiano F. G. Fiorillo +1
Primordial black holes are a possible component of dark matter, and a most promising way of investigating them is through the product of their Hawking evaporation. As a result of t…
