Supermassive black hole scalarization and effective field theory
Farid Thaalba, Pedro G. S. Fernandes, Thomas P. Sotiriou
A model in which black hole scalarization occurs for supermassive black holes, while their less massive counterparts remain unscalarized, has been recently proposed. We explore whe…

Exotic compact objects and light bosonic fields
Farid Thaalba, Giulia Ventagli, Thomas P. Sotiriou
In this note, we discuss the effect of light, non-gauge, bosonic degrees of freedom on the exterior spacetime of an exotic compact object. We show that such fields generically intr…

Spherical collapse in scalar-Gauss-Bonnet gravity: taming ill-posedness with a Ricci coupling
Farid Thaalba, Miguel Bezares, Nicola Franchini +1
We study spherical collapse of a scalar cloud in scalar-Gauss-Bonnet gravity - a theory in which black holes can develop scalar hair if they are in a certain mass range. We show th…
