Scalar wave scattering by black holes embedded in dark matter halos
Shi-Qian Hu, Federico Piazza
We study the scattering of massless scalar waves by static black holes embedded in dark matter halos. The halo is modelled by means of a Hernquist profile, for which the Einstein e…
Constraining the anomalous coupling of gravitational waves with double pulsar
Diego Santos de Jesus, Hermano Velten, Federico Piazza
We revisit the decay of the orbital period in binary systems that occurs due to the emission of gravitational waves in the context of modified gravity models where the coupling $G_…
Extreme Mass Ratio Inspirals with Scalar Hair
Adrien Kuntz, Riccardo Penco, Federico Piazza
Stellar mass objects orbiting around supermassive black holes are primary targets for future gravitational wave detectors like LISA. However, in theories beyond general relativity,…
Effective field theory for gravitational radiation in scalar-tensor gravity
Adrien Kuntz, Federico Piazza, Filippo Vernizzi
A light scalar degree of freedom, as the one possibly responsible for the accelerated expansion of the Universe, could leave observable traces in the inspiral gravitational wave si…
Limits on the anomalous speed of gravitational waves from binary pulsars
Hermano Velten, Jose Beltrán Jiménez, Federico Piazza
A large class of modified theories of gravity used as models for dark energy predict a propagation speed for gravitational waves which can differ from the speed of light. This diff…
Minimal cosmography
Federico Piazza, Thomas Schucker
The minimal requirement for cosmography - a nondynamical description of the universe - is a prescription for calculating null geodesics, and timelike geodesics as a function of the…
