- Title
Cosmological black holes as voids progenitors: simulations.

- Abstract
Abstract  Cosmological black holes (CBH), i.e. black holes with masses of the order of $$10^{13}\div 10^{14} M_{\odot}$$ , have been proposed as possible progenitors of galaxy voids. The presence of a CBH in the central region of a void should induce significant gravitational lensing effects and in this paper we discuss such gravitational signatures using simulated data. These signatures may be summarized as follows: (1) a blind spot in the projected position of the CBH where no objects can be detected; (2) an excess of faint secondary images; (3) an excess of double images having a characteristic angular separation. All these signatures are shown to be detectable in future deep surveys.
