DESCRIPTION:The zero-point fluctuations of quantum fields react to the pre
 sence of gravity through the phenomena of quantum vacuum polarization and 
 particle creation. Despite the far-reaching implications of semiclassical 
 effects in black holes and cosmology\, we still have an incomplete underst
 anding of their ultimate consequences for gravitational collapse and hydro
 static equilibrium. In this talk\, I will illustrate the ways in which the
  quantum vacuum may change the standard black hole paradigm. Firstly\, I w
 ill analyze the properties of the Boulware vacuum through the numerical ca
 lculation of renormalized stress-energy tensors in spacetimes describing t
 hin shells in equilibrium with an empty (Minkowski) interior. Secondly\, I
  will show (through an s-wave approximation) how the In vacuum behaves in 
 Vaidya-like spacetimes describing the formation and evaporation of regular
  black holes.\n\nhttps://indico.ific.uv.es/event/8504/
