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 that an additional quadratic coupling of the scalar field to the Ricci sca... Read More about Spherical collapse in scalar-Gauss-Bonnet gravity: Taming ill-posedness with a Ricci coupling.
