Optical properties of dynamical axion backgrounds
Jamie I. McDonald, Luís B. Ventura
We discuss spectral distortions, time delays and refraction of light in an axion or axion-plasma background. This involves solving the full set of geodesic equations associated to…
Dark matter axion detection in the radio/mm-waveband
Richard A. Battye, Bjoern Garbrecht, Jamie I. McDonald +2
We discuss axion dark matter detection via two mechanisms: spontaneous decays and resonant conversion in neutron star magnetospheres. For decays, we show that the brightness temper…
Axion superradiance in rotating neutron stars
Francesca V. Day, Jamie I. McDonald
It is a well-known fact that compact gravitating objects admit bound state configurations for massive bosonic fields. In this work we describe a new class of superradiant instabili…
