Query: Semiclassical dynamics of horizons in spherically symmetric collapse   In this work, we consider a semiclassical description of the spherically
symmetric gravitational collapse with a massless scalar field. In particular,
we employ an effective scenario provided by holonomy corrections from loop
quantum gravity, to the homogeneous interior spacetime. The singularity that
would arise at the final stage of the corresponding classical collapse, is
resolved in this context and is replaced by a bounce. Our main purpose is to
investigate the evolution of trapped surfaces during this semiclassical
collapse. Within this setting, we obtain a threshold radius for the collapsing
shells in order to have horizons formation. In addition, we study the final
state of the collapse by employing a suitable matching at the boundary shell
from which quantum gravity effects are carried to the exterior geometry.
