Gravitational collapse in scale-dependent gravity

In this paper we study an Oppenheimer-Snyder-like gravitational collapse in the general framework of scale-dependent gravity. We explore the collapse in spherically symmetric solutions suggested both by asymptotically safe gravity (characterized by a positive $\stackrel{\texttildelow{}}{\ensuremath{\omega}}$ parameter) and by scale-dependent gravity (negative $\stackrel{\texttildelow{}}{\ensuremath{\omega}}$ parameter), when a singularity at a finite positive radial coordinate is developed. The inner geometry of the collapsing star is described, as usual, by a spatially flat Friedmann-Lema\^{\i}tre-Robertson-Walker metric, and matter is uniformly distributed without any assumptions about its equation of state. The outer asymptotically safe/scale-dependent black hole metric is smoothly matched to the inner geometry, and this yields the equation of motion of the star surface, energy density, pressure, and equation of state of the collapsing matter. We study in detail the proper-time evolution of the event and apparent horizons. Finally, the constraints of the energy conditions on the equation of state, and its properties, are considered and discussed.
