The effect of photon-axion-like particle conversions in galaxy clusters on very high energy γ-ray spectra
Manuel Meyer, Dieter Horns, Luca Maccione +3
Very high energy (VHE, energy >~ 100 GeV) γ-rays originating from extragalactic sources interact with low energy photons of background radiation fields and produce electron-positro…
Evidence for an axion-like particle from blazar spectra?
Marco Roncadelli, Alessandro De Angelis, Giorgio Galanti +1
Observations with the Imaging Atmospheric Cherenkov Telescopes H.E.S.S., MAGIC, CANGAROO III and VERITAS have shown that the Universe is more transparent than expected to gamma ray…
Photon-axion conversion in Active Galactic Nuclei?
Nicola Bassan, Marco Roncadelli
Axion-Like Particles (ALPs) are the focus of intense current research. We analyze photon-ALP conversion in the context of relativistic jet models of Active Galactic Nuclei (AGN) fo…
