On the near-horizon geometry of an evaporating black hole
A bstractThe near-horizon geometry of evaporation black holes is determined according to the semi-classical Einstein equation. We consider spherically symmetric configurations in which the collapsing
Quantum states and their back-reacted geometries in 2D dilaton gravity
Within the Russo-Susskind-Thorlacius (RST) two-dimensional model that includes a scalar (dilaton) field we address the important question of how the classical black hole geometry is modified in a

Reissner–Nordström geometry counterpart in semiclassical gravity
We compute the renormalized stress–energy tensor (RSET) of a massless minimally coupled scalar field in the regularized Polyakov approximation, as well as its backreaction, on the classical
Probing the nature of black holes: Deep in the mHz gravitational-wave sky
Precision tests of black hole spacetimes with mHz-band gravitational-wave detectors will probe general relativity and fundamental physics in previously inaccessible regimes, and allow us to address some of these fundamental issues in the current understanding of nature.
Beyond General Relativity: Modified Theories and Non-Singular Black Holes
Einstein’s general relativity is an extremely elegant and successful theory. Recent observations coming from the LIGO/VIRGO collaboration as well as from the Event Horizon Telescope give us the
Ergoregion instability and echoes for braneworld black holes: Scalar, electromagnetic, and gravitational perturbations
In the context of higher dimensional braneworld scenario, we have argued that the occurrence of horizonless exotic compact objects, as an alternative to classical black holes, are more natural. These
Analytic description of semiclassical black-hole geometry
We study analytically the spacetime geometry of the black-hole formation and evaporation. As a simplest model of the collapse, we consider a spherical thin shell, and take the backreaction from the
Schwarzschild geometry counterpart in semiclassical gravity
We investigate the effects of vacuum polarization on vacuum static spherically symmetric spacetimes. We start from the Polyakov approximation to the renormalized stress-energy tensor (RSET) of a
