Modifying Gravity at Low Redshift
Philippe Brax, Carsten van de Bruck, Anne-Christine Davis +1
We consider the growth of cosmological perturbations in modified gravity models where a scalar field mediates a non-universal Yukawa force between different matter species. The gro…
The Effect of a Chameleon Scalar Field on the Cosmic Microwave Background
Anne-Christine Davis, Camilla A. O. Schelpe, Douglas J. Shaw
We show that a direct coupling between a chameleon-like scalar field and photons can give rise to a modified Sunyaev-Zel'dovich (SZ) effect in the Cosmic Microwave Background (CMB)…
Active Galactic Nuclei Shed Light on Axion-like-Particles
Clare Burrage, Anne-Christine Davis, Douglas J. Shaw
We demonstrate that the scatter in the luminosity relations of astrophysical objects can be used to search for axion-like-particles (ALPs). This analysis is applied to observations…
