    • In June 1991, the EGRET gamma-ray telescope on board NASA's orbiting Compton Gamma Ray Observatory had unexpectedly recognized that such AGN was one of the brightest objects in the gamma-ray sky; shortly after this image was recorded, the quasar faded from view at gamma-ray energies.

    • Parity conservation requires X to be pseudoscalar, and we shall stick to this option for definiteness. Still, all considerations to follow remain true (up to the trivial rescaling M→2M) even for a light neutral scalar boson X coupled to the photon through the effective Lagrangian Lγ′=- FμνFμν/4M=(E2-B2)/2M. We note that such a particle would mediate a long-range interaction, and so one has to make sure that no contradiction with experiment arises. See e.g. PRVDAQ 0556-2821 10.1103/PhysRevD.55.6591

    • In a previous article, we discussed the dimming of gamma-ray sources far away in space resulting from photon conversion into a light pseudoscalar X. Here we include in the calculation photon back-conversion from the X boson. A mechanism for the latter effect similar to the one discussed here was proposed by Csaki to bypass the Greisen-Zatsepin-Kuzmin cutoff for photons with energy E>1020eV coming from cosmological distances. However, it was a priori unknown whether this mechanism works at the much lower energies considered in this paper, because of the very sensitive dependence of the transition probability on the photon energy, both directly and through the photon mean free path λγ.
