Assessing the sensitivity to Axion-Like-Particle Dark Matter with very-high-energy gamma-ray observations of selected AGN and galaxy cluster pairs
Cervane Grimaud, Denys Malyshev, Emmanuel Moulin
Axion-Like-Particles (ALPs) are pseudo-scalar particles actively searched as light dark matter candidates. ALPs can couple to photons which give rise to the possibility of oscillat…
Sensitivity to Axion-like Particle dark matter with very-high-energy gamma-ray observations of Active Galactic Nuclei located behind Galaxy Clusters
Cervane Grimaud, Denys Malyshev, Emmanuel Moulin
Axion-Like-Particles (ALPs) are hypothetical pseudo-scalar particles actively searched as light dark matter candidates. The coupling of ALPs to photons can give rise to distinctive…
Diffuse continuum emission and large extended sources at MeV energies
Markus Ackermann, Denys Malyshev, Dmitry V. Malyshev
Future gamma-ray survey instruments, such as newASTROGAM and AMEGO-X, will significantly improve previous and current all-sky surveys at MeV energies. In this paper we discuss the…
Supermassive black holes and their surroundings: MeV signatures
Tullia Sbarrato, Marco Ajello, Sara Buson +5
The gravitational potential of supermassive black holes is so powerful that it triggers some of the most intense phenomena in the Universe. Accretion onto these objects and relativ…
