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…
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…
