Axion-like particle limits from multi-messenger sources
Ariane Dekker, Gonzalo Herrera, Dimitrios Kantzas
High-energy neutrino observation from the Seyfert galaxy NGC 1068 offers new insights into the non-thermal processes of active galactic nuclei. Simultaneous gamma-rays emitted by s…
Cosmic rays, gamma rays and neutrinos from discrete black hole X-ray binary ejecta
Nicolas J. Bacon, Alex J. Cooper, Dimitrios Kantzas +2
The origin of cosmic rays from outside the Solar system are unknown, as they are deflected by the interstellar magnetic field. Supernova remnants are the main candidate for cosmic…
Cosmic-ray cooling by dark matter in astrophysical jets
Dimitrios Kantzas, Francesca Calore, Marco Chianese
Astrophysical jets from powerful active galactic nuclei (AGN) have recently been proposed as promising probes of dark matter (DM) in the sub-GeV mass range. AGN launch relativistic…
Galactic transient sources with the Cherenkov Telescope Array Observatory
Cherenkov Telescope Array Observatory Consortium
A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects, isolated neutron stars exh…
