Searching for Axion-like Particles with Active Galactic Nuclei
Clare Burrage, Anne-Christine Davis, Douglas J. Shaw
Strong mixing between photons and axion-like particles in the magnetic fields of clusters of galaxies induces a scatter in the observed luminosities of compact sources in the clust…
Higgs production as a probe of Chameleon Dark Energy
Philippe Brax, Clare Burrage, Anne-Christine Davis +2
In this paper we study various particle physics effects of a light, scalar dark energy field with chameleon-like couplings to matter. We show that a chameleon model with only matte…
Collider constraints on interactions of dark energy with the Standard Model
Philippe Brax, Clare Burrage, Anne-Christine Davis +2
We study models in which a light scalar dark energy particle couples to the gauge fields of the electroweak force, the photon, Z and W bosons. Our analysis applies to a large class…
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…
