The price of regularity: core gradient instability in nonsingular dyonic black holes
Lodovico Capuano, Alessandro Longo
Spacetime singularities displayed by classical black hole solutions are expected to be cured by high-energy effects, beyond the regime of validity of General Relativity. On the oth…
When the Ringing Stops: Purely Imaginary Modes in the Ringdown Spectrum of Dynamical Black Holes
Lodovico Capuano, Thomas Lovo, Gorka Prieto-Varela +4
We extend the frequency-domain analysis of quasinormal modes in a dynamical, spherically symmetric black hole spacetime undergoing constant-rate mass evolution. In particular, we r…
Dynamical hair growth in black hole binaries in Einstein-scalar-Gauss-Bonnet gravity
Lodovico Capuano, Llibert Aresté Saló, Daniela D. Doneva +2
Within the framework of scalar-tensor theories of gravity, certain models can evade classical black hole no-hair theorems. A well-known example is Einstein-scalar-Gauss-Bonnet grav…
Systematic bias in LISA ringdown analysis due to waveform inaccuracy
Lodovico Capuano, Massimo Vaglio, Rohit S. Chandramouli +3
Inaccurate modeling of gravitational-wave signals can introduce systematic biases in the inferred source parameters. As detector sensitivities improve and signals become louder, mi…
Probing supermassive black hole scalarization with Pulsar Timing Arrays
Clemente Smarra, Lodovico Capuano, Adrien Kuntz
Scalar-tensor theories with a scalar field coupled to the Gauss-Bonnet invariant can evade no-hair theorems and allow for non-trivial scalar profiles around black holes. This coupl…
Higher-derivative corrections to the Kerr quasinormal mode spectrum
Pablo A. Cano, Lodovico Capuano, Nicola Franchini +2
We provide the most complete analysis so far of quasinormal modes of rotating black holes in a general higher-derivative extension of Einstein's theory. By finding the corrections…
Parametrized quasi-normal mode framework for modified Teukolsky equations
Pablo A. Cano, Lodovico Capuano, Nicola Franchini +2
Modifications to general relativity lead to effects in the spectrum of quasi-normal modes of black holes. In this paper, we develop a parametrized formalism to describe deviations…
Perturbations of the Vaidya metric in the frequency domain: Quasi-normal modes and tidal response
Lodovico Capuano, Luca Santoni, Enrico Barausse
The mass of a black hole can dynamically evolve due to various physical processes, such as for instance accretion, Hawking radiation, absorption of gravitational/electromagnetic wa…
Black hole hairs in scalar-tensor gravity and the lack thereof
Lodovico Capuano, Luca Santoni, Enrico Barausse
Scalar-tensor theories are a natural alternative to general relativity, as they may provide an effective dark energy phenomenology on cosmological scales while passing local tests,…
Kinetic field theory: generic effects of alternative gravity theories on non-linear cosmic density-fluctuations
Alexander Oestreicher, Lodovico Capuano, Sabino Matarrese +2
Non-linear cosmic structures contain valuable information on the expansion history of the background space-time, the nature of dark matter, and the gravitational interaction. The r…
