Spin-induced dynamical scalarization, descalarization, and stealthness in scalar-Gauss-Bonnet gravity during a black hole coalescence
Particular couplings between a scalar field and the Gauss-Bonnet invariant lead to
spontaneous scalarization of black holes. Here, we continue our work on simulating this …
