  • Black Hole Bounces on the Road to Quantum Gravity 
    Malafarina, Daniele (MDPI, 2018-08-28)
    Quantum resolutions of the space-time singularity at the end of gravitational collapse may provide hints towards the properties of a final theory of Quantum-Gravity. The mechanism by which the singularity is avoided and ...
  • MOTION OF SPINNING PARTICLES IN NON ASYMPTOTICALLY FLAT SPACETIMES 
    Toshmatov, Bobir; Rahimov, Ozodbek; Ahmedov, Bobomurat; Malafarina, Daniele (Springer Verlag, 2020-07)
    The assumption of asymptotic flatness for isolated astrophysical bodies may be considered an approximation when one considers a cosmological context where a cosmological constant or vacuum energy is present. In this framework ...
  • Note on the mass–radius relations for spherical compact objects in general relativity with semi-classical corrections 
    Nussupbekov, Ayan; Malafarina, Daniele (SpringerOpen, 2020-03-12)
    We consider the effects that modifications to general relativity (GR) at high densities may have on the structure of spherical compact objects. Such effects can be modeled via semi-classical corrections that are manifest ...
  • ON THE PROPERTIES OF A DEFORMED EXTENSION OF THE NUT SPACE-TIME 
    Narzilloev, Bakhtiyor; Malafarina, Daniele; Abdujabbarov, Ahmadjon; Bambi, Cosimo (Springer Verlag, 2020-08)
    We consider a class of space-times given by a stationary extension of the Zipoy–Voorhees metric that was found by Halilsoy. We show that the solutions do not describe rotating sources but must be interpreted, similarly to ...
  • A TOY MODEL FOR A BABY UNIVERSE INSIDE A BLACK HOLE 
    Chakrabarty, Hrishikesh; Abdujabbarov, Ahmadjon; Malafarina, Daniele; Bambi, Cosimo (Springer Verlag, 2020-05)
    We present a dynamical toy model for an expanding universe inside a black hole. The model is built by matching a spherically symmetric collapsing matter cloud to an expanding Friedmann–Robertson–Walker universe through a ...
