We give detailed predictions for the spectral signatures arising from photon-particle oscillations in astrophysical objects. The calculations include quantum electrodynamic effects and effects due to active relativistic plasma. We show that, by studying the spectra of compact sources, it may be possible to directly detect (pseudo-)scalar particles, such as the axion, with much greater sensitivity, by up to three orders of magnitude, than is currently achievable by other methods. In particular… 
Cosmic Analogs of the Stern-Gerlach Experiment and the Detection of Light Bosons
We show that, by studying the arrival times of radio pulses from highly magnetized pulsars, it may be possible to detect light spin-0 bosons (such as axions and axion-like particles) with a much

Conversion of photons into axions under the presence of a strong magnetic field can dim the radiation from magnetized astrophysical objects. Here we perform a detailed calculation aimed at
Axion-like particle effects on the polarization of cosmic high-energy gamma sources
Various satellite-borne missions are being planned to measure the polarization of a large number of gamma-ray bursts (GRBs). We show that the polarization pattern resulting from the current models of
Photon and axion oscillation in a magnetized medium: A general treatment
Pseudoscalar particles, with almost zero mass and very weak coupling to the visible matter, arise in many extensions of the standard model of particle physics. Their mixing with photons in the

We show that, by studying the arrival times of radio pulses from highly-magnetized transient beamed sources, it may be possible to detect light pseudo-scalar particles, such as axions and axion-like
X-ray polarization signals from magnetars with axion-like-particles
A bstractAxion-like-particles (ALPs) produced in the core of a magnetar can convert to photons in the magnetosphere, giving rise to novel features in the X-ray spectrum. Since ALPs only mix with the
A complete 3D numerical study of the effects of pseudoscalar–photon mixing on quasar polarizations
We present the results of three-dimensional simulations of quasar polarizations in the presence of pseudoscalar–photon mixing in the intergalactic medium. The intergalactic magnetic field is assumed
Photon propagation and the very high energy γ-ray spectra of blazars: how transparent is the Universe?
Recent findings by γ -ray Cherenkov telescopes suggest a higher transparency of the Universe to very high energy (VHE) photons than expected from current models of the extragalactic background light.

We propose that axionlike particles (ALPs) with a two-photon vertex, consistent with all astrophysical and laboratory bounds, may lead to a detectable signature in the spectra of high-energy
Constraining photon–axion oscillations using quasar spectra
Using quasar spectra from the SDSS survey, we constrain the possibility of photon–axion oscillations as a source of dimming of high redshift objects. Such a process has been suggested as an

Recent experiments suggest that polarized photons may couple significantly to pseudoscalar particles such as axions. We study the possible observational signatures of axion-photon coupling for
Dimming of supernovae by photon-pseudoscalar conversion and the intergalactic plasma
It has been suggested recently that the observed dimming of distant type Ia supernovae may be a consequence of mixing of the photons with very light axions. We point out that the effect of the
Effects of axion-photon mixing on gamma-ray spectra from magnetized astrophysical sources
Astrophysical {gamma}-ray sources come in a variety of sizes and magnetizations. We deduce general conditions under which {gamma}-ray spectra from such sources would be significantly affected by
Mixing of the photon with low-mass particles.
TLDR
A formalism which is adapted to study the evolution of a photon (axion, graviton) beam in the presence of external fields is developed, and the possibility of detecting axions by a measurement of the magnetically induced birefringence of the vacuum is discussed.
