On the near-horizon geometry of an evaporating black hole

- PhysicsJournal of High Energy Physics
- 2018

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

- PhysicsPhysical Review D
- 2022

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

- PhysicsClassical and Quantum Gravity
- 2021

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

- PhysicsExperimental astronomy
- 2021

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

- Physics
- 2020

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

- Physics
- 2020

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

- Physics
- 2020

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

- PhysicsPhysical Review D
- 2020

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…
