The significance of first post-adiabatic contributions for scalar charge measurements with intermediate and extreme mass ratio inspirals
Susanna Barsanti, Ollie Burke, Andrea Maselli +3
We present the first self-force-based beyond-GR waveform model incorporating post-adiabatic orbital evolution for intermediate- and extreme-mass-ratio inspirals in theories of grav…
Beyond black hole spectroscopy: Quasinormal mode contamination by massless scalars
Miguel Yulo Asuncion, Giovanni D'Addario, Thomas P. Sotiriou
Testing General Relativity (GR) with black hole ringdowns has conventionally focused on attempting to detect shifts away from the quasinormal mode (QNM) frequencies of the Kerr met…
Minimum mass, maximum charge and hyperbolicity in scalar Gauss-Bonnet gravity
Dario Rossi, Leonardo Gualtieri, Thomas P. Sotiriou
We study the loss of hyperbolicity of perturbation equations for black hole solutions of scalar Gauss-Bonnet gravity. We consider a class of coupling functions allowing for static…
Adiabatic evolution of asymmetric binaries on generic orbits with new fundamental fields I: characterization of gravitational wave fluxes
Sara Gliorio, Matteo Della Rocca, Susanna Barsanti +3
We investigate the dynamics of asymmetric binaries in extensions of General Relativity featuring a massless scalar field non-minimally coupled to gravity, focusing on the interplay…
From mergers to collapse: scalarisation dynamics in neutron star binaries
Llibert Aresté Saló, Ricard Aguilera-Miret, Miguel Bezares +1
We present the first fully non-linear evolutions of binary neutron star mergers in a moving-punctures approach in Einstein-scalar-Gauss-Bonnet gravity. We study both linear and qua…
Probing fundamental physics with Extreme Mass Ratio Inspirals: a full Bayesian inference for scalar charge
Lorenzo Speri, Susanna Barsanti, Andrea Maselli +6
Extreme Mass Ratio Inspirals (EMRIs) are key sources for the future space-based gravitational wave detector LISA, and are considered promising probes of fundamental physics. Here,…
