Toward the CompactHedron: Bounds on Neutron Stars from Microscopic Principles
Thomas Apostolidis, Alessandro Longo, Borna Salehian +1
We investigate the implications of causality and positivity for the tidal Love numbers of gravitating objects. We work within the framework of point-particle effective field theory…
Dynamical tidal response of neutron stars: From effective field theory to gravitational waveforms
Thomas Apostolidis, Valerio De Luca, Leonardo Gualtieri +3
We investigate the fully relativistic dynamical tidal response of neutron stars up to second order in the frequency. Combining the worldline effective field theory for extended gra…
Love numbers of black holes and compact objects
María J. Rodríguez, Luca Santoni, Adam R. Solomon
The Love numbers of a gravitating body are response coefficients encoding its tidal deformability. In compact binary systems, they appear in the gravitational waveform during the i…
Nonlinear Relativistic Tidal Response of Neutron Stars
Paolo Pani, Massimiliano Maria Riva, Luca Santoni +2
We investigate the nonlinear tidal response of relativistic neutron stars by computing the fully relativistic, static, quadratic Love numbers. Using both the worldline effective fi…
Dynamical Tidal Response of Schwarzschild Black Holes
Oscar Combaluzier--Szteinsznaider, Daniel Glazer, Austin Joyce +2
Dynamical Love numbers capture the conservative response of an object to a time-dependent external tidal gravitational field. We compute the dynamical Love numbers of Schwarzschild…
Symmetries of Vanishing Nonlinear Love Numbers of Schwarzschild Black Holes
Oscar Combaluzier-Szteinsznaider, Lam Hui, Luca Santoni +2
The tidal Love numbers parametrize the conservative induced tidal response of self-gravitating objects. It is well established that asymptotically-flat black holes in four-dimensio…
Vanishing of Quadratic Love Numbers of Schwarzschild Black Holes
Simon Iteanu, Massimiliano Maria Riva, Luca Santoni +2
The induced conservative tidal response of self-gravitating objects in general relativity is parametrized in terms of a set of coefficients, which are commonly referred to as Love…
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…
Ladder Symmetries and Love Numbers of Reissner--Nordström Black Holes
Mudit Rai, Luca Santoni
It is well known that asymptotically flat black holes in general relativity have vanishing tidal Love numbers. In the case of Schwarzschild and Kerr black holes, this property has…
Vanishing of Nonlinear Tidal Love Numbers of Schwarzschild Black Holes
Massimiliano Maria Riva, Luca Santoni, Nikola Savić +1
It is well known that asymptotically flat Schwarzschild black holes in general relativity in four spacetime dimensions have vanishing induced linear tidal response. We extend this…
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,…
An analytic approach to quasinormal modes for coupled linear systems
Lam Hui, Alessandro Podo, Luca Santoni +1
Quasinormal modes describe the ringdown of compact objects deformed by small perturbations. In generic theories of gravity that extend General Relativity, the linearized dynamics o…
Black hole superradiance with (dark) matter accretion
Lam Hui, Y. T. Albert Law, Luca Santoni +3
Studies of black hole superradiance often focus on the growth of a cloud in isolation, accompanied by the spin-down of the black hole. In this paper, we consider the additional eff…
Black Hole Ringdown as a Probe for Dark Energy
Johannes Noller, Luca Santoni, Enrico Trincherini +1
Under the assumption that a dynamical scalar field is responsible for the current acceleration of the Universe, we explore the possibility of probing its physics in black hole merg…
Black Hole Hair from Scalar Dark Matter
Lam Hui, Daniel Kabat, Xinyu Li +2
We show that a black hole surrounded by scalar dark matter develops scalar hair. This is the generalization of a phenomenon pointed out by Jacobson, that a minimally coupled scalar…
