Black hole accretion discs and screened scalar hair.

Davis, Anne C. and Gregory, Ruth and Jha, Rahul (2016) 'Black hole accretion discs and screened scalar hair.', Journal of cosmology and astroparticle physics., 2016 (10). 024.


We present a novel way to investigate scalar field profiles around black holes with an accretion disc for a range of models where the Compton wavelength of the scalar is large compared to other length scales. By analysing the problem in ``Weyl" coordinates, we are able to calculate the scalar profiles for accretion discs in the static Schwarzschild, as well as rotating Kerr, black holes. We comment on observational effects.
