The Axion-Photon Mixing and the Extragalactic Magnetic Background: Plateau Regimes, Resonances, and Non-Gaussian Boosts
Andrea Addazi, Yi-Fu Cai, Salvatore Capozziello +2
We present an analytical treatment of Axion-Like-Particle (ALP)--photon mixing with extragalactic background light (EBL) attenuation for constant, Gaussian-stochastic, and non-Gaus…
Exotic PeVatrons as sources of ultra-high-energy gamma rays
Andrea Addazi, Salvatore Capozziello, Qingyu Gan
We explore novel classes of exotic astrophysical sources capable of producing ultra-high-energy gamma rays extending beyond the PeV scale, motivated by quantum gravity scenarios an…
Gravitational waves in minimal Maxwell gravity
Salvatore Capozziello, Qingyu Gan
We discuss the conversion mechanism from scalar field to gravitational waves in magnetic background in gravity minimal coupled to the Maxwell electrodynamics. Applying the c…
Excess Radiation from Axion-Photon Conversion
Andrea Addazi, Salvatore Capozziello, Qingyu Gan +2
Two notable anomalies in radio observations -- the excess radiation in the Rayleigh-Jeans tail of the cosmic microwave background, revealed by ARCADE2, and the twice-deeper absorpt…
Superoscillations in High Energy Physics and Gravity
Andrea Addazi, Qingyu Gan
We explore superoscillations within the context of classical and quantum field theories, presenting novel solutions to Klein-Gordon's, Dirac's, Maxwell's and Einstein's equations.…
Resonant Graviton-Photon Conversion with Stochastic Magnetic Field in the Expanding Universe
Andrea Addazi, Salvatore Capozziello, Qingyu Gan
We investigate graviton-photon oscillations sourced by cosmological magnetic fields from Gertsenshtein effect. We adopt a robust perturbative approach and we find that the conversi…
