New constraints on light Axion-Like Particles using Chandra Transmission Grating Spectroscopy of the powerful cluster-hosted quasar H1821+643
Júlia Sisk Reynés, James H. Matthews, Christopher S. Reynolds +3
Axion-Like Particles (ALPs) are predicted by several Beyond the Standard Model theories, in particular, string theory. In the presence of an external magnetic field perpendicular t…
The Fourier formalism for relativistic axion-photon conversion, with astrophysical applications
M. C. David Marsh, James H. Matthews, Christopher Reynolds +1
We study the weak mixing of photons and relativistic axion-like particles (axions) in plasmas with background magnetic fields, . We show that, to leading order in the axio…
Axion-photon conversion in strongly magnetised plasmas
Alexander J. Millar, Sebastian Baum, Matthew Lawson +1
Axion dark matter can resonantly convert to photons in the magnetosphere of neutron stars, possibly giving rise to radio signals observable on Earth. This method for the indirect d…
