Axion signals from neutron star populations
U. Bhura, R. A. Battye, J. I. McDonald +1
Neutron stars provide a powerful probe of axion dark matter, especially in higher frequency ranges where there remain fewer laboratory constraints. Populations of neutron stars nea…
Cosmological gravity on all scales III: non-linear matter power spectrum in phenomenological modified gravity
Sankarshana Srinivasan, Daniel B Thomas, Richard Battye
Model-independent tests of gravity with cosmology are important when testing extensions to the standard cosmological model. To maximise the impact of these tests one requires predi…
Searching for Time-Dependent Axion Dark Matter Signals in Pulsars
R. A. Battye, M. J. Keith, J. I. McDonald +3
Axion dark matter can be converted into photons in the magnetospheres of neutron stars leading to a spectral line centred on the Compton wavelength of the axion. Due to the rotatio…
Towards Robust Constraints on Axion Dark Matter using PSR J1745-2900
R. A. Battye, J. Darling, J. McDonald +1
We apply novel, recently developed plasma ray-tracing techniques to model the propagation of radio photons produced by axion dark matter in neutron star magnetospheres and combine…
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…
