Tolman-Bondi collapse in scalar-tensor theories as a probe of gravitational memory
In cosmological models with a varying gravitational constant, it is not clear whether primordial black holes preserve the value of G at their formation epoch. We investigate this question by using the Tolman-Bondi model to study the evolution of a background scalar field when a black hole forms from the …
