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

Anatomy of a thermal black hole mimicker

We are entering a new era to test the strong gravity regime around astrophysical black holes. The possibility that they are actually horizonless ultracompact objects and then free from the

Testing the nature of dark compact objects: a status report

Very compact objects probe extreme gravitational fields and may be the key to understand outstanding puzzles in fundamental physics. These include the nature of dark matter, the fate of spacetime

Exotic compact objects with soft hair

Motivated by the lack of a general parametrization for exotic compact objects, we construct a class of perturbative solutions valid for small (but otherwise generic) multipolar deviations from a
