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…
Orbital evolution of asymmetric binaries within accreting environments
Albert Radulea, Marcelo E. Rubio, Konstantinos Kritos +1
Extreme mass-ratio inspirals embedded in accretion disks provide a natural arena for studying the interplay between relativistic orbital dynamics and environmental effects. In this…
Axial tidal Love numbers of black holes in matter environments
Simone D'Onofrio, Sayak Datta, Andrea Maselli
We study the axial (magnetic) tidal Love numbers of a Schwarzschild black hole surrounded by a spherically symmetric matter distribution. While the formalism developed here is gene…
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…
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,…
Neutron stars and the cosmological constant problem
Giulia Ventagli, Pedro G. S. Fernandes, Andrea Maselli +2
Phase transitions can play an important role in the cosmological constant problem, allowing the underlying vacuum energy, and therefore the value of the cosmological constant, to c…
