Radio Line Properties of Axion Dark Matter Conversion in Neutron Stars
R. A. Battye, B. Garbrecht, J. I. McDonald +1
Axions are well-motivated candidates for dark matter. Recently, much interest has focused on the detection of photons produced by the resonant conversion of axion dark matter in ne…

Cosmological gravity on all scales II: Model independent modified gravity -body simulations
Sankarshana Srinivasan, Daniel B Thomas, Francesco Pace +1
Model-independent constraints on modified gravity models hitherto exist mainly on linear scales. A recently developed formalism presented a consistent parameterisation that is vali…

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…
