From scalar clouds around evaporating black holes to boson star
Daniel Neves, João G. Rosa
We study, for the first time, the evolution of a scalar cloud bound to an evaporating black hole. Our simulations of the associated Schrödinger-Poisson system for non-relativistic…

Superradiant Darwinism: survival of the lightest axion
Daniel Neves, João G. Rosa
We study the dynamical evolution of superradiant instabilities of rotating black holes for multiple axion fields with comparable masses, motivated by string theory constructions, w…
