Pulsar Nulling and Vacuum Radio Emission from Axion Clouds
Andrea Caputo, Samuel J. Witte, Alexander A. Philippov +1
Non-relativistic axions can be efficiently produced in in the polar caps of pulsars, resulting in the formation of a dense cloud of gravitationally bound axions. Here, we investiga…
Adiabatic Axion-Photon Mixing Near Neutron Stars
Jonas Tjemsland, Jamie McDonald, Samuel J. Witte
One of the promising new proposals to search for axions in astrophysical environments is to look for narrow radio lines produced from the resonant conversion of axion dark matter f…
Generalized Ray Tracing for Axions in Astrophysical Plasmas
J. I. McDonald, S. J. Witte
Ray tracing plays a vital role in black hole imaging, modeling the emission mechanisms of pulsars, and deriving signatures from physics beyond the Standard Model. In this work we f…
