We study the imprint of light scalar fields on gravitational waves from extreme mass-ratio inspirals—binary systems with a very large mass asymmetry. We first show that, to leading order in the mass ratio, any effects of the scalar on the waveform ar... Read More about Detecting Massive Scalar Fields with Extreme Mass-Ratio Inspirals.

Black hole minimum size and scalar charge in shift-symmetric theories (2023)
Journal Article
Thaalba, F., Antoniou, G., & Sotiriou, T. P. (2023). Black hole minimum size and scalar charge in shift-symmetric theories. Classical and Quantum Gravity, 40(15), Article 155002. https://doi.org/10.1088/1361-6382/acdd42

It is known that, for shift-symmetric scalars, only a linear coupling with the Gauss-Bonnet invariant can introduce black hole hair. Such hairy black holes have a minimum mass, determined by the coupling of this interaction, and a scalar charge that...
