Dark energy and Equivalence Principle constraints from astrophysical tests of the stability of the fine-structure constant

C. J. A. P. Martins, A. M. M. Pinho, R. F. C. Alves +3

Astrophysical tests of the stability of fundamental couplings, such as the fine-structure constant $\alpha$, are becoming an increasingly powerful probe of new physics. Here we discuss…
