Stellar kinematics from the symmetron fifth force in the Milky Way disk (2018)
Journal Article
O’Hare, C. A., & Burrage, C. (2018). Stellar kinematics from the symmetron fifth force in the Milky Way disk. Physical Review D, 98(6), Article 064019. https://doi.org/10.1103/PhysRevD.98.064019

It has been shown that the presence of nonminimally coupled scalar fields giving rise to a fifth force can noticeably alter dynamics on galactic scales. Such a fifth force must be screened in the Solar System but if unscreened it can have similar obs... Read More about Stellar kinematics from the symmetron fifth force in the Milky Way disk.

Tests of chameleon gravity (2018)
Journal Article
Burrage, C., & Sakstein, J. (2018). Tests of chameleon gravity. Living Reviews in Relativity, 21, https://doi.org/10.1007/s41114-018-0011-x

Theories of modified gravity, where light scalars with non-trivial self-interactions and non-minimal couplings to matter—chameleon and symmetron theories—dynamically suppress deviations from general relativity in the solar system. On other scales, th... Read More about Tests of chameleon gravity.

The shape dependence of chameleon screening (2018)
Journal Article
Burrage, C., Copeland, E. J., Moss, A., & Stevenson, J. A. (2018). The shape dependence of chameleon screening. Journal of Cosmology and Astroparticle Physics, 2018(1), https://doi.org/10.1088/1475-7516/2018/01/056

Chameleon scalar fields can screen their associated fifth forces from detection by changing their mass with the local density. These models are an archetypal example of a screening mechanism, and have become an important target for both cosmological... Read More about The shape dependence of chameleon screening.
